* configure: Use a separate config_components.h header for $ALL_COMPONENTSMartin Storsjö2022-03-16
| | | | | | | | This avoids unnecessary rebuilds of most source files if only the list of enabled components has changed, but not the other properties of the build, set in config.h. Signed-off-by: Martin Storsjö <martin@martin.st>

* avcodec/nvdec: Explicitly mark codecs that support 444 output formatsPhilip Langdale2019-02-16
| | | | | | | | | 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.

* avcodec: Implement mpeg1 nvdec hwaccelPhilip Langdale2017-11-20
| | | | | Once I remembered that there's a separate decoder type for mpeg1, even though params struct is shared with mpeg2, everything worked.
* avcodec: Refactor common nvdec hwaccel logicPhilip Langdale2017-11-20
| | | | | | | | | 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.
* avcodec: Implement mpeg2 nvdec hwaccelPhilip Langdale2017-11-18
This is mostly straight-forward. The weird part is that it should just work for mpeg1, but I see corruption in my test cases, so I'm going to try and fix that separately.
