Andreas Rheinhardt	e35dfe864d	avcodec/avcodec: Add FFHWAccel, hide internals of AVHWAccel This commit is the AVHWAccel analogue of commit 20f972701806be20a77f808db332d9489343bb78: It moves the private fields of AVHWAccel to a new struct FFHWAccel extending AVHWAccel in an internal header (namely hwaccel_internal.h).

Hendrik Leppkes	b3e938ef80	avcodec/nvdec_mpeg4: fix order of quant matrix coefficients The matrix coefficients are stored permutated for the IDCT, rather then in plain raster order, and need to be un-permutated for the hardware.	2 years ago
Andreas Rheinhardt	500bbd584d	avcodec/mpeg4video: Factor non-codec stuff out into a header of its own This avoids including mpegvideo.h in mpeg4_unpack_bframes_bsf.c. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
Andreas Rheinhardt	746e7102be	avcodec/mpegvideo: Move encoder-only stuff to a new header Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago

Philip Langdale	83c7ac2e47	avcodec/nvdec: Explicitly mark codecs that support 444 output formats With the introduction of HEVC 444 support, we technically have two codecs that can handle 444 - HEVC and MJPEG. In the case of MJPEG, it can decode, but can only output one of the semi-planar formats. That means we need additional logic to decide whether to use a 444 output format or not.	6 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
