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	4c7b023d56	avcodec: Refactor common nvdec hwaccel logic The 'simple' hwaccels (not h.264 and hevc) all use the same bitstream management and reference lookup logic so let's refactor all that into common functions. I verified that casting a signed int -1 to unsigned char produces 255 according to the C language specification.	7 years ago
Philip Langdale	5a0f6b099f	avcodec: Fix reference data type for nvdec vc1 hwaccel I took the reference lookup code from the vp9 hwaccel where the type is unsigned char, but for vc1, the type is signed int. This is particularly important because the value used when there's no reference is different (255 vs -1). It didn't seem to break anything, but for mpeg1/2/4, this mistake caused decode errors.	7 years ago
Philip Langdale	912ceba61b	avcodec: Implement vc1 nvdec hwaccel This hwaccel is interesting because it also works for wmv3/9 content, which is not supported by the nvidia parser used by cuviddec.	7 years ago
