Capability queries define what each interface supports. The +described API is only defined for video capture cards. The relevant subset +applies to radio cards. Teletext interfaces talk the existing VTX API. +<P> +<H3>Capability Query Ioctl</H3> +The <B>VIDIOCGCAP</B> ioctl call is used to obtain the capability +information for a video device. The <b>struct video_capability</b> object +passed to the ioctl is completed and returned. It contains the following +information +<P> +<TABLE> +<TR><TD><b>name[32]</b><TD>Canonical name for this interface</TD> +<TR><TD><b>type</b><TD>Type of interface</TD> +<TR><TD><b>channels</b><TD>Number of radio/tv channels if appropriate</TD> +<TR><TD><b>audios</b><TD>Number of audio devices if appropriate</TD> +<TR><TD><b>maxwidth</b><TD>Maximum capture width in pixels</TD> +<TR><TD><b>maxheight</b><TD>Maximum capture height in pixels</TD> +<TR><TD><b>minwidth</b><TD>Minimum capture width in pixels</TD> +<TR><TD><b>minheight</b><TD>Minimum capture height in pixels</TD> +</TABLE> +<P> +The type field lists the capability flags for the device. These are +as follows +<P> +<TABLE> +<TR><TH>Name</TH><TH>Description</TH> +<TR><TD><b>VID_TYPE_CAPTURE</b><TD>Can capture to memory</TD> +<TR><TD><b>VID_TYPE_TUNER</b><TD>Has a tuner of some form</TD> +<TR><TD><b>VID_TYPE_TELETEXT</b><TD>Has teletext capability</TD> +<TR><TD><b>VID_TYPE_OVERLAY</b><TD>Can overlay its image onto the frame buffer</TD> +<TR><TD><b>VID_TYPE_CHROMAKEY</b><TD>Overlay is Chromakeyed</TD> +<TR><TD><b>VID_TYPE_CLIPPING</b><TD>Overlay clipping is supported</TD> +<TR><TD><b>VID_TYPE_FRAMERAM</b><TD>Overlay overwrites frame buffer memory</TD> +<TR><TD><b>VID_TYPE_SCALES</b><TD>The hardware supports image scaling</TD> +<TR><TD><b>VID_TYPE_MONOCHROME</b><TD>Image capture is grey scale only</TD> +<TR><TD><b>VID_TYPE_SUBCAPTURE</b><TD>Capture can be of only part of the image</TD> +</TABLE> +<P> +The minimum and maximum sizes listed for a capture device do not imply all +that all height/width ratios or sizes within the range are possible. A +request to set a size will be honoured by the largest available capture +size whose capture is no large than the requested rectangle in either +direction. For example the quickcam has 3 fixed settings. +<P> +<H3>Frame Buffer</H3> +Capture cards that drop data directly onto the frame buffer must be told the +base address of the frame buffer, its size and organisation. This is a +privileged ioctl and one that eventually X itself should set. +<P> +The <b>VIDIOCSFBUF</b> ioctl sets the frame buffer parameters for a capture +card. If the card does not do direct writes to the frame buffer then this +ioctl will be unsupported. The <b>VIDIOCGFBUF</b> ioctl returns the +currently used parameters. The structure used in both cases is a +<b>struct video_buffer</b>. +<P> +<TABLE> +<TR><TD><b>void *base</b></TD><TD>Base physical address of the buffer</TD> +<TR><TD><b>int height</b></TD><TD>Height of the frame buffer</TD> +<TR><TD><b>int width</b></TD><TD>Width of the frame buffer</TD> +<TR><TD><b>int depth</b></TD><TD>Depth of the frame buffer</TD> +<TR><TD><b>int bytesperline</b></TD><TD>Number of bytes of memory between the start of two adjacent lines</TD> +</TABLE> +<P> +Note that these values reflect the physical layout of the frame buffer. +The visible area may be smaller. In fact under XFree86 this is commonly the +case. XFree86 DGA can provide the parameters required to set up this ioctl. +Setting the base address to NULL indicates there is no physical frame buffer +access. +<P> +<H3>Capture Windows</H3> +The capture area is described by a <b>struct video_window</b>. This defines +a capture area and the clipping information if relevant. The +<b>VIDIOCGWIN</b> ioctl recovers the current settings and the +<b>VIDIOCSWIN</b> sets new values. A successful call to <b>VIDIOCSWIN</b> +indicates that a suitable set of parameters have been chosen. They do not +indicate that exactly what was requested was granted. The program should +call <b>VIDIOCGWIN</b> to check if the nearest match was suitable. The +<b>struct video_window</b> contains the following fields. +<P> +<TABLE> +<TR><TD><b>x</b><TD>The X co-ordinate specified in X windows format.</TD> +<TR><TD><b>y</b><TD>The Y co-ordinate specified in X windows format.</TD> +<TR><TD><b>width</b><TD>The width of the image capture.</TD> +<TR><TD><b>height</b><TD>The height of the image capture.</TD> +<TR><TD><b>chromakey</b><TD>A host order RGB32 value for the chroma key.</TD> +<TR><TD><b>flags</b><TD>Additional capture flags.</TD> +<TR><TD><b>clips</b><TD>A list of clipping rectangles. <em>(Set only)</em></TD> +<TR><TD><b>clipcount</b><TD>The number of clipping rectangles. <em>(Set only)</em></TD> +</TABLE> +<P> +Clipping rectangles are passed as an array.

Overlay capturing +(i.e. PCI-PCI transfer to the frame buffer of the video card) +is activated by passing the <b>VIDIOCCAPTURE</b> ioctl a value of 1, and +disabled by passing it a value of 0. +<P> +Some capture devices can capture a subfield of the image they actually see. +This is indicated when VIDEO_TYPE_SUBCAPTURE is defined. +The video_capture describes the time and special subfields to capture. +The video_capture structure contains the following fields. +<P> +<TABLE> +<TR><TD><b>x</b></TD><TD>X co-ordinate of source rectangle to grab</TD> +<TR><TD><b>y</b></TD><TD>Y co-ordinate of source rectangle to grab</TD> +<TR><TD><b>width</b></TD><TD>Width of source rectangle to grab</TD> +<TR><TD><b>height</b></TD><TD>Height of source rectangle to grab</TD> +<TR><TD><b>decimation</b></TD><TD>Decimation to apply</TD> +<TR><TD><b>flags</b></TD><TD>Flag settings for grabbing</TD> +</TABLE> +The available flags are +<P> +<TABLE> +<TR><TH>Name</TH><TH>Description</TH> +<TR><TD><b>VIDEO_CAPTURE_ODD</b><TD>Capture only odd frames</TD> +<TR><TD><b>VIDEO_CAPTURE_EVEN</b><TD>Capture only even frames</TD> +</TABLE> +<P> +<H3>Video Sources</H3> +Each video4linux video or audio device captures from one or more +source <b>channels</b>.

It is not defined whether parameters such as colour +settings or tuning are maintained across a channel switch. The caller should +maintain settings as desired for each channel.

It is up to the caller to set format and size (using +the VIDIOCSPICT and VIDIOCSWIN ioctls) and then to pass a suitable +size buffer and length to the function. Not all devices will support +read operations. +<P> +A second way to handle image capture is via the mmap interface if supported. +To use the mmap interface a user first sets the desired image size and depth +properties. Next the VIDIOCGMBUF ioctl is issued. This reports the size +of buffer to mmap and the offset within the buffer for each frame. The +number of frames supported is device dependent and may only be one. +<P> +The video_mbuf structure contains the following fields +<P> +<TABLE> +<TR><TD><b>size</b><TD>The number of bytes to map</TD> +<TR><TD><b>frames</b><TD>The number of frames</TD> +<TR><TD><b>offsets</b><TD>The offset of each frame</TD> +</TABLE> +<P> +Once the mmap has been made the VIDIOCMCAPTURE ioctl starts the +capture to a frame using the format and image size specified in the +video_mmap (which should match or be below the initial query size). +When the VIDIOCMCAPTURE ioctl returns the frame is <em>not</em> +captured yet, the driver just instructed the hardware to start the +capture. The application has to use the VIDIOCSYNC ioctl to wait +until the capture of a frame is finished. VIDIOCSYNC takes the frame +number you want to wait for as argument. +<p> +It is allowed to call VIDIOCMCAPTURE multiple times (with different +frame numbers in video_mmap->frame of course) and thus have multiple +outstanding capture requests. A simple way do to double-buffering +using this feature looks like this: +<pre> +/* setup everything */ +VIDIOCMCAPTURE(0) +while (whatever) { + VIDIOCMCAPTURE(1) + VIDIOCSYNC(0) + /* process frame 0 while the hardware captures frame 1 */ + VIDIOCMCAPTURE(0) + VIDIOCSYNC(1) + /* process frame 1 while the hardware captures frame 0 */ +} +</pre> +Note that you are <em>not</em> limited to only two frames. The API +allows up to 32 frames, the VIDIOCGMBUF ioctl returns the number of +frames the driver granted. Thus it is possible to build deeper queues +to avoid loosing frames on load peaks. +<p> +While capturing to memory the driver will make a "best effort" attempt +to capture to screen as well if requested. This normally means all +frames that "miss" memory mapped capture will go to the display. +<P> +A final ioctl exists to allow a device to obtain related devices if a +driver has multiple components (for example video0 may not be associated +with vbi0 which would cause an intercast display program to make a bad +mistake). The VIDIOCGUNIT ioctl reports the unit numbers of the associated +devices if any exist. The video_unit structure has the following fields. +<P> +<TABLE> +<TR><TD><b>video</b><TD>Video capture device</TD> +<TR><TD><b>vbi</b><TD>VBI capture device</TD> +<TR><TD><b>radio</b><TD>Radio device</TD> +<TR><TD><b>audio</b><TD>Audio mixer</TD> +<TR><TD><b>teletext</b><TD>Teletext device</TD> +</TABLE> +<P> +<H3>RDS Datastreams</H3> +For radio devices that support it, it is possible to receive Radio Data +System (RDS) data by means of a read() on the device. The data is packed in +groups of three, as follows: +<TABLE> +<TR><TD>First Octet</TD><TD>Least Significant Byte of RDS Block</TD></TR> +<TR><TD>Second Octet</TD><TD>Most Significant Byte of RDS Block +<TR><TD>Third Octet</TD><TD>Bit 7:</TD><TD>Error bit.

Logitech +does not currently provide information for developers, but many people +have engineered several solutions for non-Microsoft use of the Color +Quickcam. + +1.1 Motivation + + I spent a number of hours trying to get my camera to work, and I +hope this document saves you some time. My camera will not work with +the 2.2.13 kernel as distributed, but with a few patches to the +module, I was able to grab some frames. See 4.0, Future Work. + + + +2.0 Compilation, Installation, and Configuration + + The c-qcam depends on parallel port support, video4linux, and the +Color Quickcam. It is also nice to have the parallel port readback +support enabled. I enabled these as modules during the kernel +configuration. The appropriate flags are: + + CONFIG_PRINTER M for lp.o, parport.o parport_pc.o modules + CONFIG_PNP_PARPORT M for autoprobe.o IEEE1284 readback module + CONFIG_PRINTER_READBACK M for parport_probe.o IEEE1284 readback module + CONFIG_VIDEO_DEV M for videodev.o video4linux module + CONFIG_VIDEO_CQCAM M for c-qcam.o Color Quickcam module + + With these flags, the kernel should compile and install the modules. +To record and monitor the compilation, I use: + + (make zlilo ; \ + make modules; \ + make modules_install ; + depmod -a ) &>log & + less log # then a capital 'F' to watch the progress + +But that is my personal preference. + +2.2 Configuration + + The configuration requires module configuration and device +configuration. I like kmod or kerneld process with the +/etc/modprobe.conf file so the modules can automatically load/unload as +they are used. The video devices could already exist, be generated +using MAKEDEV, or need to be created. The following sections detail +these procedures. + + +2.1 Module Configuration + + Using modules requires a bit of work to install and pass the +parameters. Understand that entries in /etc/modprobe.conf of: + + alias parport_lowlevel parport_pc + options parport_pc io=0x378 irq=none + alias char-major-81 videodev + alias char-major-81-0 c-qcam + +will cause the kmod/modprobe to do certain things. If you are +using kmod, then a request for a 'char-major-81-0' will cause +the 'c-qcam' module to load. If you have other video sources with +modules, you might want to assign the different minor numbers to +different modules. + +2.2 Device Configuration + + At this point, we need to ensure that the device files exist. +Video4linux used the /dev/video* files, and we want to attach the +Quickcam to one of these. + + ls -lad /dev/video* # should produce a list of the video devices + +If the video devices do not exist, you can create them with: + + su + cd /dev + for ii in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 ; do + mknod video$ii c 81 $ii # char-major-81-[0-16] + chown root.root video$ii # owned by root + chmod 600 video$ii # read/writable by root only + done + + Lots of people connect video0 to video and bttv, but you might want +your c-qcam to mean something more: + + ln -s video0 c-qcam # make /dev/c-qcam a working file + ln -s c-qcam video # make /dev/c-qcam your default video source + + But these are conveniences. The important part is to make the proper +special character files with the right major and minor numbers. All +of the special device files are listed in ../devices.txt. If you +would like the c-qcam readable by non-root users, you will need to +change the permissions. + +3.0 Troubleshooting + + If the sample program below, v4lgrab, gives you output then +everything is working. + + v4lgrab | wc # should give you a count of characters + + Otherwise, you have some problem. + + The c-qcam is IEEE1284 compatible, so if you are using the proc file +system (CONFIG_PROC_FS), the parallel printer support +(CONFIG_PRINTER), the IEEE 1284 system,(CONFIG_PRINTER_READBACK), you +should be able to read some identification from your quickcam with + + modprobe -v parport + modprobe -v parport_probe + cat /proc/parport/PORTNUMBER/autoprobe +Returns: + CLASS:MEDIA; + MODEL:Color QuickCam 2.0; + MANUFACTURER:Connectix; + + A good response to this indicates that your color quickcam is alive +and well. A common problem is that the current driver does not +reliably detect a c-qcam, even though one is attached. In this case, + + modprobe -v c-qcam +or + insmod -v c-qcam + + Returns a message saying "Device or resource busy" Development is +currently underway, but a workaround is to patch the module to skip +the detection code and attach to a defined port. Check the +video4linux mailing list and archive for more current information. + +3.1 Checklist: + + Can you get an image? + v4lgrab >qcam.ppm ; wc qcam.ppm ; xv qcam.ppm + + Is a working c-qcam connected to the port? + grep ^ /proc/parport/?/autoprobe + + Do the /dev/video* files exist? + ls -lad /dev/video + + Is the c-qcam module loaded? + modprobe -v c-qcam ; lsmod + + Does the camera work with alternate programs? cqcam, etc? + + + + +4.0 Future Work / current workarounds + + It is hoped that this section will soon become obsolete, but if it +isn't, you might try patching the c-qcam module to add a parport=xxx +option as in the bw-qcam module so you can specify the parallel port: + + insmod -v c-qcam parport=0 + +And bypass the detection code, see ../../drivers/char/c-qcam.c and +look for the 'qc_detect' code and call. + + Note that there is work in progress to change the video4linux API, +this work is documented at the video4linux2 site listed below. + + +9.0 --- A sample program using v4lgrabber, + +This program is a simple image grabber that will copy a frame from the +first video device, /dev/video0 to standard output in portable pixmap +format (.ppm) Using this like: 'v4lgrab | convert - c-qcam.jpg' +produced this picture of me at + http://mug.sys.virginia.edu/~drf5n/extras/c-qcam.jpg + +-------------------- 8< ---------------- 8< ----------------------------- + +/* Simple Video4Linux image grabber. */ +/* + * Video4Linux Driver Test/Example Framegrabbing Program + * + * Compile with: + * gcc -s -Wall -Wstrict-prototypes v4lgrab.c -o v4lgrab + * Use as: + * v4lgrab >image.ppm + * + * Copyright (C) 1998-05-03, Phil Blundell <philb@gnu.org> + * Copied from http://www.tazenda.demon.co.uk/phil/vgrabber.c + * with minor modifications (Dave Forrest, drf5n@virginia.edu). + * + */ + +#include <unistd.h> +#include <sys/types.h> +#include <sys/stat.h> +#include <fcntl.h> +#include <stdio.h> +#include <sys/ioctl.h> +#include <stdlib.h> + +#include <linux/types.h> +#include <linux/videodev.h> + +#define FILE "/dev/video0" + +/* Stole this from tvset.c */ + +#define READ_VIDEO_PIXEL(buf, format, depth, r, g, b) \ +{ \ + switch (format) \ + { \ + case VIDEO_PALETTE_GREY: \ + switch (depth) \ + { \ + case 4: \ + case 6: \ + case 8: \ + (r) = (g) = (b) = (*buf++ << 8);\ + break;

There are several formats of the TV standards. +And not every TV decoder is able to handle every format. Also the every +combination is supported by the driver. There are currently 11 different +tv broadcast formats all aver the world. + +The CCIR defines parameters needed for broadcasting the signal. +The CCIR has defined different standards: A,B,D,E,F,G,D,H,I,K,K1,L,M,N,... +The CCIR says not much about about the colorsystem used !!! +And talking about a colorsystem says not to much about how it is broadcast. + +The CCIR standards A,E,F are not used any more. + +When you speak about NTSC, you usually mean the standard: CCIR - M using +the NTSC colorsystem which is used in the USA, Japan, Mexico, Canada +and a few others. + +When you talk about PAL, you usually mean: CCIR - B/G using the PAL +colorsystem which is used in many Countries. + +When you talk about SECAM, you mean: CCIR - L using the SECAM Colorsystem +which is used in France, and a few others. + +There the other version of SECAM, CCIR - D/K is used in Bulgaria, China, +Slovakai, Hungary, Korea (Rep.), Poland, Rumania and a others. + +The CCIR - H uses the PAL colorsystem (sometimes SECAM) and is used in +Egypt, Libya, Sri Lanka, Syrain Arab. Rep. + +The CCIR - I uses the PAL colorsystem, and is used in Great Britain, Hong Kong, +Ireland, Nigeria, South Africa. + +The CCIR - N uses the PAL colorsystem and PAL frame size but the NTSC framerate, +and is used in Argentinia, Uruguay, an a few others + +We do not talk about how the audio is broadcast ! + +A rather good sites about the TV standards are: +http://www.sony.jp/ServiceArea/Voltage_map/ +http://info.electronicwerkstatt.de/bereiche/fernsehtechnik/frequenzen_und_normen/Fernsehnormen/ +and http://www.cabl.com/restaurant/channel.html + +Other weird things around: NTSC 4.43 is a modificated NTSC, which is mainly +used in PAL VCR's that are able to play back NTSC.

But you find nothing PAL N +specific in the the registers. Seem that you have to reuse a other standard +to generate PAL N, maybe it would work if you use the PAL M settings. + +========================== + +2. How do I get this damn thing to work + +Load zr36067.o. If it can't autodetect your card, use the card=X insmod +option with X being the card number as given in the previous section. +To have more than one card, use card=X1[,X2[,X3,[X4[..]]]] + +To automate this, add the following to your /etc/modprobe.conf: + +options zr36067 card=X1[,X2[,X3[,X4[..]]]] +alias char-major-81-0 zr36067 + +One thing to keep in mind is that this doesn't load zr36067.o itself yet. It +just automates loading. If you start using xawtv, the device won't load on +some systems, since you're trying to load modules as a user, which is not +allowed ("permission denied"). A quick workaround is to add 'Load "v4l"' to +XF86Config-4 when you use X by default, or to run 'v4l-conf -c <device>' in +one of your startup scripts (normally rc.local) if you don't use X. Both +make sure that the modules are loaded on startup, under the root account. + +=========================== + +3. What mainboard should I use (or why doesn't my card work) + +<insert lousy disclaimer here>. In short: good=SiS/Intel, bad=VIA. + +Experience tells us that people with a Buz, on average, have more problems +than users with a DC10+/LML33. Also, it tells us that people owning a VIA- +based mainboard (ktXXX, MVP3) have more problems than users with a mainboard +based on a different chipset. Here's some notes from Andrew Stevens: +-- +Here's my experience of using LML33 and Buz on various motherboards: + +VIA MVP3 + Forget it. Pointless. Doesn't work. +Intel 430FX (Pentium 200) + LML33 perfect, Buz tolerable (3 or 4 frames dropped per movie) +Intel 440BX (early stepping) + LML33 tolerable. Buz starting to get annoying (6-10 frames/hour) +Intel 440BX (late stepping) + Buz tolerable, LML3 almost perfect (occasional single frame drops) +SiS735 + LML33 perfect, Buz tolerable. +VIA KT133(*) + LML33 starting to get annoying, Buz poor enough that I have up. + +Both 440BX boards were dual CPU versions. +-- +Bernhard Praschinger later added: +-- +AMD 751 + Buz perfect-tolerable +AMD 760 + Buz perfect-tolerable +-- +In general, people on the user mailinglist won't give you much of a chance +if you have a VIA-based motherboard. They may be cheap, but sometimes, you'd +rather want to spend some more money on better boards. In general, VIA +mainboard's IDE/PCI performance will also suck badly compared to others. +You'll noticed the DC10+/DC30+ aren't mentioned anywhere in the overview. +Basically, you can assume that if the Buz works, the LML33 will work too. If +the LML33 works, the DC10+/DC30+ will work too. They're most tolerant to +different mainboard chipsets from all of the supported cards. + +If you experience timeouts during capture, buy a better mainboard or lower +the quality/buffersize during capture (see 'Concerning buffer sizes, quality, +output size etc.'). If it hangs, there's little we can do as of now. Check +your IRQs and make sure the card has its own interrupts. + +=========================== + +4. Programming interface + +This driver conforms to video4linux and video4linux2, both can be used to +use the driver. Since video4linux didn't provide adequate calls to fully +use the cards' features, we've introduced several programming extensions, +which are currently officially accepted in the 2.4.x branch of the kernel. +These extensions are known as the v4l/mjpeg extensions. See zoran.h for +details (structs/ioctls). + +Information - video4linux: +http://roadrunner.swansea.linux.org.uk/v4lapi.shtml +Documentation/video4linux/API.html +/usr/include/linux/videodev.h + +Information - video4linux/mjpeg extensions: +./zoran.h +(also see below) + +Information - video4linux2: +http://www.thedirks.org/v4l2/ +/usr/include/linux/videodev2.h +http://www.bytesex.org/v4l/ + +More information on the video4linux/mjpeg extensions, by Serguei +Miridonovi and Rainer Johanni: +-- +The ioctls for that interface are as follows: + +BUZIOC_G_PARAMS +BUZIOC_S_PARAMS + +Get and set the parameters of the buz. The user should always do a +BUZIOC_G_PARAMS (with a struct buz_params) to obtain the default +settings, change what he likes and then make a BUZIOC_S_PARAMS call. + +BUZIOC_REQBUFS + +Before being able to capture/playback, the user has to request +the buffers he is wanting to use. Fill the structure +zoran_requestbuffers with the size (recommended: 256*1024) and +the number (recommended 32 up to 256). There are no such restrictions +as for the Video for Linux buffers, you should LEAVE SUFFICIENT +MEMORY for your system however, else strange things will happen .... +On return, the zoran_requestbuffers structure contains number and +size of the actually allocated buffers. +You should use these numbers for doing a mmap of the buffers +into the user space. +The BUZIOC_REQBUFS ioctl also makes it happen, that the next mmap +maps the MJPEG buffer instead of the V4L buffers. + +BUZIOC_QBUF_CAPT +BUZIOC_QBUF_PLAY + +Queue a buffer for capture or playback. The first call also starts +streaming capture. When streaming capture is going on, you may +only queue further buffers or issue syncs until streaming +capture is switched off again with a argument of -1 to +a BUZIOC_QBUF_CAPT/BUZIOC_QBUF_PLAY ioctl. + +BUZIOC_SYNC + +Issue this ioctl when all buffers are queued. This ioctl will +block until the first buffer becomes free for saving its +data to disk (after BUZIOC_QBUF_CAPT) or for reuse (after BUZIOC_QBUF_PLAY). + +BUZIOC_G_STATUS + +Get the status of the input lines (video source connected/norm). + +For programming example, please, look at lavrec.c and lavplay.c code in +lavtools-1.2p2 package (URL: http://www.cicese.mx/~mirsev/DC10plus/) +and the 'examples' directory in the original Buz driver distribution. + +Additional notes for software developers: + + The driver returns maxwidth and maxheight parameters according to + the current TV standard (norm). Therefore, the software which + communicates with the driver and "asks" for these parameters should + first set the correct norm. Well, it seems logically correct: TV + standard is "more constant" for current country than geometry + settings of a variety of TV capture cards which may work in ITU or + square pixel format. Remember that users now can lock the norm to + avoid any ambiguity. +-- +Please note that lavplay/lavrec are also included in the MJPEG-tools +(http://mjpeg.sf.net/). + +=========================== + +5. Applications + +Applications known to work with this driver: + +TV viewing: +* xawtv +* kwintv +* probably any TV application that supports video4linux or video4linux2. + +MJPEG capture/playback: +* mjpegtools/lavtools (or Linux Video Studio) +* gstreamer +* mplayer + +General raw capture: +* xawtv +* gstreamer +* probably any application that supports video4linux or video4linux2 + +Video editing: +* Cinelerra +* MainActor +* mjpegtools (or Linux Video Studio) + +=========================== + +6. Concerning buffer sizes, quality, output size etc. + +The zr36060 can do 1:2 JPEG compression. This is really the theoretical +maximum that the chipset can reach. The driver can, however, limit compression +to a maximum (size) of 1:4. The reason for this is that some cards (e.g. Buz) +can't handle 1:2 compression without stopping capture after only a few minutes. +With 1:4, it'll mostly work. If you have a Buz, use 'low_bitrate=1' to go into +1:4 max. compression mode. + +100% JPEG quality is thus 1:2 compression in practice. So for a full PAL frame +(size 720x576). The JPEG fields are stored in YUY2 format, so the size of the +fields are 720x288x16/2 bits/field (2 fields/frame) = 207360 bytes/field x 2 = +414720 bytes/frame (add some more bytes for headers and DHT (huffman)/DQT +(quantization) tables, and you'll get to something like 512kB per frame for +1:2 compression. For 1:4 compression, you'd have frames of half this size. + +Some additional explanation by Martin Samuelsson, which also explains the +importance of buffer sizes: +-- +> Hmm, I do not think it is really that way. With the current (downloaded +> at 18:00 Monday) driver I get that output sizes for 10 sec: +> -q 50 -b 128 : 24.283.332 Bytes +> -q 50 -b 256 : 48.442.368 +> -q 25 -b 128 : 24.655.992 +> -q 25 -b 256 : 25.859.820 + +I woke up, and can't go to sleep again. I'll kill some time explaining why +this doesn't look strange to me. + +Let's do some math using a width of 704 pixels. I'm not sure whether the Buz +actually use that number or not, but that's not too important right now. + +704x288 pixels, one field, is 202752 pixels. Divided by 64 pixels per block; +3168 blocks per field. Each pixel consist of two bytes; 128 bytes per block; +1024 bits per block. 100% in the new driver mean 1:2 compression; the maximum +output becomes 512 bits per block. Actually 510, but 512 is simpler to use +for calculations. + +Let's say that we specify d1q50. We thus want 256 bits per block; times 3168 +becomes 811008 bits; 101376 bytes per field. We're talking raw bits and bytes +here, so we don't need to do any fancy corrections for bits-per-pixel or such +things. 101376 bytes per field. + +d1 video contains two fields per frame. Those sum up to 202752 bytes per +frame, and one of those frames goes into each buffer. + +But wait a second! -b128 gives 128kB buffers! It's not possible to cram +202752 bytes of JPEG data into 128kB! + +This is what the driver notice and automatically compensate for in your +examples. Let's do some math using this information: + +128kB is 131072 bytes. In this buffer, we want to store two fields, which +leaves 65536 bytes for each field. Using 3168 blocks per field, we get +20.68686868... available bytes per block; 165 bits. We can't allow the +request for 256 bits per block when there's only 165 bits available! The -q50 +option is silently overridden, and the -b128 option takes precedence, leaving +us with the equivalence of -q32. + +This gives us a data rate of 165 bits per block, which, times 3168, sums up +to 65340 bytes per field, out of the allowed 65536. The current driver has +another level of rate limiting; it won't accept -q values that fill more than +6/8 of the specified buffers. (I'm not sure why. "Playing it safe" seem to be +a safe bet. Personally, I think I would have lowered requested-bits-per-block +by one, or something like that.) We can't use 165 bits per block, but have to +lower it again, to 6/8 of the available buffer space: We end up with 124 bits +per block, the equivalence of -q24. With 128kB buffers, you can't use greater +than -q24 at -d1. (And PAL, and 704 pixels width...) + +The third example is limited to -q24 through the same process. The second +example, using very similar calculations, is limited to -q48. The only +example that actually grab at the specified -q value is the last one, which +is clearly visible, looking at the file size. +-- + +Conclusion: the quality of the resulting movie depends on buffer size, quality, +whether or not you use 'low_bitrate=1' as insmod option for the zr36060.c +module to do 1:4 instead of 1:2 compression, etc. + +If you experience timeouts, lowering the quality/buffersize or using +'low_bitrate=1 as insmod option for zr36060.o might actually help, as is +proven by the Buz. + +=========================== + +7. It hangs/crashes/fails/whatevers! Help! + +Make sure that the card has its own interrupts (see /proc/interrupts), check +the output of dmesg at high verbosity (load zr36067.o with debug=2, +load all other modules with debug=1). Check that your mainboard is favorable +(see question 2) and if not, test the card in another computer. Also see the +notes given in question 3 and try lowering quality/buffersize/capturesize +if recording fails after a period of time. + +If all this doesn't help, give a clear description of the problem including +detailed hardware information (memory+brand, mainboard+chipset+brand, which +MJPEG card, processor, other PCI cards that might be of interest), give the +system PnP information (/proc/interrupts, /proc/dma, /proc/devices), and give +the kernel version, driver version, glibc version, gcc version and any other +information that might possibly be of interest. Also provide the dmesg output +at high verbosity. See 'Contacting' on how to contact the developers. + +=========================== + +8.

Thus the arbiter defaults to +the video function at power-up and parks there during no requests for +bus access. This is desirable since the video will request the bus more +often. However, the audio will have highest bus access priority. Thus +the audio will have first access to the bus even when issuing a request +after the video request but before the PCI external arbiter has granted +access to the Bt879. Neither function can preempt the other once on the +bus. The duration to empty the entire video PCI FIFO onto the PCI bus is +very short compared to the bus access latency the audio PCI FIFO can +tolerate. + + +430FX Compatibility Mode +------------------------ + +When using the 430FX PCI, the following rules will ensure +compatibility: + + (1) Deassert REQ at the same time as asserting FRAME. + (2) Do not reassert REQ to request another bus transaction until after + finish-ing the previous transaction. + +Since the individual bus masters do not have direct control of REQ, a +simple logical-or of video and audio requests would violate the rules. +Thus, both the arbiter and the initiator contain 430FX compatibility +mode logic. To enable 430FX mode, set the EN_TBFX bit as indicated in +Device Control Register on page 104. + +When EN_TBFX is enabled, the arbiter ensures that the two compatibility +rules are satisfied. Before GNT is asserted by the PCI arbiter, this +internal arbiter may still logical-or the two requests. However, once +the GNT is issued, this arbiter must lock in its decision and now route +only the granted request to the REQ pin. The arbiter decision lock +happens regardless of the state of FRAME because it does not know when +FRAME will be asserted (typically - each initiator will assert FRAME on +the cycle following GNT). When FRAME is asserted, it is the initiator s +responsibility to remove its request at the same time. It is the +arbiters responsibility to allow this request to flow through to REQ and +not allow the other request to hold REQ asserted. The decision lock may +be removed at the end of the transaction: for example, when the bus is +idle (FRAME and IRDY). The arbiter decision may then continue +asynchronously until GNT is again asserted. + + +Interfacing with Non-PCI 2.1 Compliant Core Logic +------------------------------------------------- + +A small percentage of core logic devices may start a bus transaction +during the same cycle that GNT is de-asserted. This is non PCI 2.1 +compliant. To ensure compatibility when using PCs with these PCI +controllers, the EN_VSFX bit must be enabled (refer to Device Control +Register on page 104). When in this mode, the arbiter does not pass GNT +to the internal functions unless REQ is asserted. This prevents a bus +transaction from starting the same cycle as GNT is de-asserted. This +also has the side effect of not being able to take advantage of bus +parking, thus lowering arbitration performance. The Bt879 drivers must +query for these non-compliant devices, and set the EN_VSFX bit only if +required. + diff --git a/Documentation/video4linux/bttv/Sound-FAQ b/Documentation/video4linux/bttv/Sound-FAQ new file mode 100644 index 0000000..b8c9c26 --- /dev/null +++ b/Documentation/video4linux/bttv/Sound-FAQ @@ -0,0 +1,148 @@ + +bttv and sound mini howto +========================= + +There are alot of different bt848/849/878/879 based boards available. +Making video work often is not a big deal, because this is handled +completely by the bt8xx chip, which is common on all boards.

Looks like some driver hacking is required. +Below is a do-it-yourself description for you. + +The bt8xx chips have 32 general purpose pins, and registers to control +these pins. One register is the output enable register +(BT848_GPIO_OUT_EN), it says which pins are actively driven by the +bt848 chip. Another one is the data register (BT848_GPIO_DATA), where +you can get/set the status if these pins. They can be used for input +and output. + +Most grabber board vendors use these pins to control an external chip +which does the sound routing. But every board is a little different. +These pins are also used by some companies to drive remote control +receiver chips. Some boards use the i2c bus instead of the gpio pins +to connect the mux chip. + +As mentioned above, there is a array which holds the required +informations for each known board. You basically have to create a new +line for your board. The important fields are these two: + +struct tvcard +{ + [ ... ] + u32 gpiomask; + u32 audiomux[6]; /* Tuner, Radio, external, internal, mute, stereo */ +}; + +gpiomask specifies which pins are used to control the audio mux chip. +The corresponding bits in the output enable register +(BT848_GPIO_OUT_EN) will be set as these pins must be driven by the +bt848 chip. + +The audiomux[] array holds the data values for the different inputs +(i.e. which pins must be high/low for tuner/mute/...). This will be +written to the data register (BT848_GPIO_DATA) to switch the audio +mux. + + +What you have to do is figure out the correct values for gpiomask and +the audiomux array.

Benoit (benoits@servicepro.com) Dec 14, 1996 +---------------------------------------------------------------------------- + +Document version 1.0 + +ACKNOWLEDGMENTS +---------------- +This document was made based on 'C' code for Linux from Gideon le Grange +(legrang@active.co.za or legrang@cs.sun.ac.za) in 1994, and elaborations from +Frans Brinkman (brinkman@esd.nl) in 1996. The results reported here are from +experiments that the author performed on his own setup, so your mileage may +vary... I make no guarantees, claims or warranties to the suitability or +validity of this information. No other documentation on the AIMS +Lab (http://www.aimslab.com/) RadioTrack card was made available to the +author. This document is offered in the hopes that it might help users who +want to use the RadioTrack card in an environment other than MS Windows. + +WHY THIS DOCUMENT? +------------------ +I have a RadioTrack card from back when I ran an MS-Windows platform. After +converting to Linux, I found Gideon le Grange's command-line software for +running the card, and found that it was good! Frans Brinkman made a +comfortable X-windows interface, and added a scanning feature. For hack +value, I wanted to see if the tuner could be tuned beyond the usual FM radio +broadcast band, so I could pick up the audio carriers from North American +broadcast TV channels, situated just below and above the 87.0-109.0 MHz range. +I did not get much success, but I learned about programming ioports under +Linux and gained some insights about the hardware design used for the card. + +So, without further delay, here are the details. + + +PHYSICAL DESCRIPTION +-------------------- +The RadioTrack card is an ISA 8-bit FM radio card. The radio frequency (RF) +input is simply an antenna lead, and the output is a power audio signal +available through a miniature phone plug. Its RF frequencies of operation are +more or less limited from 87.0 to 109.0 MHz (the commercial FM broadcast +band). Although the registers can be programmed to request frequencies beyond +these limits, experiments did not give promising results. The variable +frequency oscillator (VFO) that demodulates the intermediate frequency (IF) +signal probably has a small range of useful frequencies, and wraps around or +gets clipped beyond the limits mentioned above. + + +CONTROLLING THE CARD WITH IOPORT +-------------------------------- +The RadioTrack (base) ioport is configurable for 0x30c or 0x20c. Only one +ioport seems to be involved. The ioport decoding circuitry must be pretty +simple, as individual ioport bits are directly matched to specific functions +(or blocks) of the radio card. This way, many functions can be changed in +parallel with one write to the ioport. The only feedback available through +the ioports appears to be the "Stereo Detect" bit. + +The bits of the ioport are arranged as follows: + + MSb LSb ++------+------+------+--------+--------+-------+---------+--------+ +| VolA | VolB | ???? | Stereo | Radio | TuneA | TuneB | Tune | +| (+) | (-) | | Detect | Audio | (bit) | (latch) | Update | +| | | | Enable | Enable | | | Enable | ++------+------+------+--------+--------+-------+---------+--------+ + + +VolA .

After detecting a set bit, the chip neatly waits +till the start of a frame, captures it and it goes back to off. +Smart ppl will notice the problem here.

There are a couple +of minor differences due to the fact that the amount of data returned +with each frame varies, and no doubt there are discrepancies due to my +misunderstanding of the API. I intend to convert this driver to the +new V4L2 API when it has stabilized more. + +------ Current state -------------------------------------- + +The driver is capable of overlaying a video image in screen, and +even capable of grabbing frames. It uses the BIGPHYSAREA patch +to allocate lots of large memory blocks when tis patch is +found in the kernel, but it doesn't need it. +The consequence is that, when loading the driver as a module, +the module may tell you it's out of memory, but 'free' says +otherwise. The reason is simple; the modules wants its memory +contiguous, not fragmented, and after a long uptime there +probably isn't a fragment of memory large enough... + +The driver uses a double buffering scheme, which should really +be an n-way buffer, depending on the size of allocated framebuffer +and the requested grab-size/format. +This current version also fixes a dead-lock situation during irq +time, which really, really froze my system... :) + +Good luck. + Pauline |
