+ * it will work but it will have an impact on performance.
+ *
+ * In practice, avpkt->data should have 4 byte alignment at minimum and
+ * samples should be 16 byte aligned unless the CPU doesn't need it
+ * (AltiVec and SSE do).
+ *
+ * @note Codecs which have the CODEC_CAP_DELAY capability set have a delay

+ * @param[in] avpkt The input AVPacket containing the input buffer.

+ * TODO:
+ * - optimize: color space conversion, ...
+ * - implement options to set the min/max number of strips?
+ * MAYBE:
+ * - "optimally" split the frame into several non-regular areas
+ *   using a separate codebook pair for each area and approximating
+ *   the area by several rectangular strips (generally not full width ones)
+ *   (use quadtree splitting? a simple fixed-granularity grid?)
+ *
+ *
+ * version 2014-01-23 Rl
+ * - added option handling for flexibility
+ *
+ * version 2014-01-21 Rl
+ * - believe it or not, now we get even smaller files, with better quality
+ *   (which means I missed an optimization earlier :)
+ *
+ * version 2014-01-20 Rl
+ * - made the encoder compatible with vintage decoders
+ *   and added some yet unused code for possible future
+ *   incremental codebook updates
+ * - fixed a small memory leak
+ *
+ * version 2013-04-28 Rl
+ * - bugfixed codebook optimization logic
+ *
+ * version 2013-02-14 Rl
+ * "Valentine's Day" version:
+ * - made strip division more robust
+ * - minimized bruteforcing the number of strips,
+ *   (costs some R/D but speeds up compession a lot), the heuristic
+ *   assumption is that score as a function of the number of strips has
+ *   one wide minimum which moves slowly, of course not fully true
+ * - simplified codebook generation,
+ *   the old code was meant for other optimizations than we actually do
+ * - optimized the codebook generation / error estimation for MODE_MC
+ *
+ * version 2013-02-12 Rl
+ * - separated codebook training sets, avoided the transfer of wasted bytes,
+ *   which yields both better quality and smaller files
+ * - now using the correct colorspace (TODO: move conversion to libswscale)
+ *
+ * version 2013-02-08 Rl
+ * - fixes/optimization in multistrip encoding and codebook size choice,
+ *   quality/bitrate is now better than that of the binary proprietary encoder

+/*
+ * - Principles of Operation -
+ *
+ * The CrystalHD decoder operates at the bitstream level - which is an even
+ * higher level than the decoding hardware you typically see in modern GPUs.
+ * This means it has a very simple interface, in principle. You feed demuxed
+ * packets in one end and get decoded picture (fields/frames) out the other.
+ *
+ * Of course, nothing is ever that simple. Due, at the very least, to b-frame
+ * dependencies in the supported formats, the hardware has a delay between
+ * when a packet goes in, and when a picture comes out. Furthermore, this delay
+ * is not just a function of time, but also one of the dependency on additional
+ * frames being fed into the decoder to satisfy the b-frame dependencies.
+ *
+ * As such, a pipeline will build up that is roughly equivalent to the required
+ * DPB for the file being played. If that was all it took, things would still
+ * be simple - so, of course, it isn't.
+ *
+ * The hardware has a way of indicating that a picture is ready to be copied out,
+ * but this is unreliable - and sometimes the attempt will still fail so, based
+ * on testing, the code will wait until 3 pictures are ready before starting
+ * to copy out - and this has the effect of extending the pipeline.
+ *
+ * Finally, while it is tempting to say that once the decoder starts outputting
+ * frames, the software should never fail to return a frame from a decode(),
+ * this is a hard assertion to make, because the stream may switch between
+ * differently encoded content (number of b-frames, interlacing, etc) which
+ * might require a longer pipeline than before. If that happened, you could
+ * deadlock trying to retrieve a frame that can't be decoded without feeding
+ * in additional packets.
+ *
+ * As such, the code will return in the event that a picture cannot be copied
+ * out, leading to an increase in the length of the pipeline. This in turn,
+ * means we have to be sensitive to the time it takes to decode a picture;
+ * We do not want to give up just because the hardware needed a little more
+ * time to prepare the picture! For this reason, there are delays included
+ * in the decode() path that ensure that, under normal conditions, the hardware
+ * will only fail to return a frame if it really needs additional packets to
+ * complete the decoding.
+ *
+ * Finally, to be explicit, we do not want the pipeline to grow without bound
+ * for two reasons: 1) The hardware can only buffer a finite number of packets,
+ * and 2) The client application may not be able to cope with arbitrarily long
+ * delays in the video path relative to the audio path. For example. MPlayer
+ * can only handle a 20 picture delay (although this is arbitrary, and needs
+ * to be extended to fully support the CrystalHD where the delay could be up
+ * to 32 pictures - consider PAFF H.264 content with 16 b-frames).

-/*
- * Features and limitations:
- * - currently no compression is performed,
- *   in fact the size of the data is 9/8 the size of the image in 8bpp
- * - uses only a global standard palette
- * - tested with IE 5.0, Opera for BeOS, NetPositive (BeOS), and Mozilla (BeOS).
- *
- * Reference documents:
- * http://www.goice.co.jp/member/mo/formats/gif.html
- * http://astronomy.swin.edu.au/pbourke/dataformats/gif/
- * http://www.dcs.ed.ac.uk/home/mxr/gfx/2d/GIF89a.txt
- *
- * this url claims to have an LZW algorithm not covered by Unisys patent:
- * http://www.msg.net/utility/whirlgif/gifencod.html
- * could help reduce the size of the files _a lot_...
- * some sites mentions an RLE type compression also.
