CrystalHD decoder support v7
The Broadcom CrystalHD decoder chips provide hardware video decoding for a number of video formats. It does so using a memory:memory interface where a compressed bitstream is fed in and decompressed pictures are copied out. As such, it works independent of any graphics hardware in the system. Features supported in this initial version: * Support for Linux (using current drivers/library from git.wilsonet.com) * Support for 70015 hardware * Formats: MPEG2, MPEG4 Part 2, H.264, VC1 and DivX 3.11 (untested) * Progressive content * Non-H.264 Interlaced content * H.264 MBAFF content Features missing in this initial version: * Support for OSX (might work - untested) * Support for Windows * Support for 70012 hardware * H.264 PAFF content Signed-off-by: Philip Langdale <philipl@overt.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

|

|
||||
/*
|
||||
* - 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 outputing
|
||||
* 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).
