/*
 * - 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.
 *
46
 * Finally, while it is tempting to say that once the decoder starts outputting
47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86
 * 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).
