* avcodec/vc1dec: fix mby_start for interlaced contentMichael Niedermayer2018-02-111-2/+2
| | | | | | Bug-Id: 1100 Bug-Id: ffmpeg/Ticket2531 Cc: libav-stable@libav.org
* lavc: Add hardware config metadata for decoders supporting hardware outputMark Thompson2017-12-191-0/+37
| | | | | | | | | This includes a pointer to the associated hwaccel for decoders using hwaccels - these will be used later to implement the hwaccel setup without needing a global list. Also added is a new file listing all hwaccels as external declarations - this will be used later to generate the hwaccel list at configure time.
* dxva: add support for new dxva2 and d3d11 hwaccel APIswm42017-06-081-0/+1
| | | | | | | | | | This also adds support to avconv (which is trivial due to the new hwaccel API being generic enough). The new decoder setup code in dxva2.c is significantly based on work by Steve Lhomme <robux4@gmail.com>, but with heavy changes/rewrites. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* intrax8: Keep a reference to the decoder blocksVittorio Giovara2016-03-291-0/+1
|
* intrax8: Pass macroblock size to ff_intrax8_common_initVittorio Giovara2016-03-291-1/+3
| | | | Helps in decoupling this code from mpegvideo.
* intrax8: Reference the current AVCodecContextVittorio Giovara2016-03-251-1/+1
| | | | It will be needed to initialize BlockDSP in the next commit.
* intrax8: Keep a reference to the context idctdspVittorio Giovara2016-03-251-1/+1
| | | | | Use it instead of the embedded mpegvideo one. Update init function signature to load it directly from the callers.

* vc1dec: Check group allocations separatedlyVittorio Giovara2016-02-251-6/+19
| | | | This avoids accessing NULL pointers in case of error.
* vc1dec: Fix leak on error for array allocationsVittorio Giovara2016-02-251-2/+5
| | | | | The deinit function in the 'error' section will correctly free everything.

* vc1dec: Drop commented out cruftVittorio Giovara2016-02-251-8/+0
|
* lavc: add profiles to AVCodecDescriptorAnton Khirnov2015-12-121-10/+3
| | | | | The profiles are a property of the codec, so it makes sense to export them through AVCodecDescriptors, not just the codec implementations.

* vc1dec: use get_bits_long and limit the read bits to 32Andreas Cadhalpun2015-06-261-1/+1

* mpegvideo: Drop flags and flags2Vittorio Giovara2015-05-221-2/+2
| | | | They are just duplicates of AVCodecContext members so use those instead.

* vc1: Do not assume seek happens after decodingLuca Barbato2014-10-041-1/+1
| | | | | | | If a seek is requested before the decoding start there is no current picture. CC: libav-stable@libav.org

* lavc: set AVCodecContext.hwaccel in ff_get_format()Anton Khirnov2014-05-111-1/+0
| | | | This way each decoder does not have to do the same thing manually.
* lavc: Add an internal wrapper around get_format()Anton Khirnov2014-05-111-1/+1
| | | | It will be useful in the following commits.
* vc1: Do not return an error when skipping b framesAlessandro Ghedini2014-04-251-1/+1
| | | | | | | | | This caused mpv (and possibly others) to fallback to software decoding after seeking a VC1 stream. Bug-Id: 667 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* mpegvideo: operate with pointers to AVFrames instead of whole structswm42014-04-091-67/+67
| | | | | | | | | | | | | The most interesting parts are initialization in ff_MPV_common_init() and uninitialization in ff_MPV_common_end(). ff_mpeg_unref_picture and ff_thread_release_buffer have additional NULL checks for Picture.f, because these functions can be called on uninitialized or partially initialized Pictures. NULL pointer checks are added to ff_thread_release_buffer() stub function. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
