Kieran Kunhya	f9d3841ae6	mpeg4video: Add support for MPEG-4 Simple Studio Profile. This is a profile supporting > 8-bit video and has a higher quality DCT	7 years ago
Mark Thompson	2fcb009011	lavc: Add hardware config metadata for decoders supporting hardware output 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.	7 years ago

Philip Langdale	6b77a10e43	avcodec: Implement mpeg4 nvdec hwaccel This was predictably nightmarish, given how ridiculous mpeg4 is. I had to stare at the cuvid parser output for a long time to work out what each field was supposed to be, and even then, I still don't fully understand some of them. Particularly: vop_coded: If I'm reading the decoder correctly, this flag will always be 1 as the decoder will not pass the hwaccel any frame where it is not 1. divx_flags: There's obviously no documentation on what the possible flags are. I simply observed that this is '0' for a normal bitstream and '5' for packed b-frames. gmc_enabled: I had a number of guesses as to what this mapped to. I picked the condition I did based on when the cuvid parser was setting flag. Also note that as with the vdpau hwaccel, the decoder needs to consume the entire frame and not the slice.	7 years ago

Derek Buitenhuis	21f9468402	avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPAT Libav, for some reason, merged this as a public API function. This will aid in future merges. A define is left for backwards compat, just in case some person used it, since it is in a public header. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	9 years ago
Rémi Denis-Courmont	d35d0c723e	vdpau: remove dysfunctional H.263 support The VDPAU API never explicitly supported H.263 in the first place. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Vittorio Giovara	4628443ca3	h263: Drop uninitialized variable use from log message	9 years ago
Gwenole Beauchesne	9f8e57efe4	vaapi: define a unique pixel format for VA-API (AV_PIX_FMT_VAAPI). Deprecate older VA pixel formats (MOCO, IDCT) as it is now very unlikely to ever be useful in the future. Only keep plain AV_PIX_FMT_VAAPI format that is aliased to the older VLD variant. This is an API change. Signed-off-by: Gwenole Beauchesne <gwenole.beauchesne@intel.com>	9 years ago

Philip Langdale	9ae766d1c6	avcodec/vdpau: Re-factor pre-hwaccel helper functions into separate header h264.h and hevc.h are mutually exclusive due to defining some of the same names. As such, we need to avoid forcing h264.h to be included if we want hevc decode acceleration to be possible. However, some of the pre-hwaccel helper functions need h264.h. To avoid messy collisions, let's move the declaration of all those helpers to a separate header which we will exclude for the hevc support (which will be hwaccel-only).
