+/*
+ * - 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).
