* avcodec: set correct return value in ff_mpeg_ref_picturePan Bian2017-11-281-1/+3
| | | | | | | | | | In function ff_mpeg_ref_picture(), it returns 0 on the error path that the return value of av_buffer_ref() is NULL. 0 indicates success, which seems to deviate from the fact. Set ret to AVERROR(ENOMEM) to propagate the error status to the callers. Signed-off-by: Pan Bian <[email protected]> Signed-off-by: Michael Niedermayer <[email protected]>

* avcodec/nvdec: More effort to make vp8 compile with gcc < 4.6Philip Langdale2017-11-261-11/+10
| | | | | | | | | | | I'm told my prefix work-around wasn't enough to make it compile, although I'm not sure why; I did some basic testing and that approach appeared to work, but I'm not in a position to do a full compile on CentOS 6 so I can't be sure of anything. I have had it confirmed that the additional change to not use named initialisers is enough to make it compile, so let's throw that into the mix too.
* avcodec/nvdec: Make vp8 initialisation more 'compatible'Philip Langdale2017-11-261-5/+14
| | | | | | | | | | | | | | | | | Ancient versions of gcc (pre 4.6) can't directly initialise members of anonymous inner unions/structs by name. https://gcc.gnu.org/bugzilla/show_bug.cgi?id=10676 Unfortunately, RHEL 6 shipped with one of these ancient versions and so we're stuck with it until approximately the heat death of the universe. Putting explicit braces into the initialisation is possibly a work-around but the behaviour there was never fully understood before direct initialisation was made to work. So, this may or may not work.

* vaapi_decode: Ignore the profile when not usefulMark Thompson2017-11-261-1/+2
| | | | | Enables VP8 decoding - the decoder places the the bitstream version in the profile field, which we want to ignore.
* vaapi: Add VP8 decode hwaccelMark Thompson2017-11-264-0/+245
|
* vp8: Add hwaccel hooksMark Thompson2017-11-263-68/+172
| | | | | | | | | | Also adds some extra fields to the main context structure that may be needed by a hwaccel decoder. The current behaviour of the WebP decoder is maintained by adding an additional field to the VP8 decoder private context to indicate that it is actually being used as WebP (no hwaccel is supported for that case).
* vaapi: Make the decode profile matching more explicitMark Thompson2017-11-261-11/+9
| | | | | Also fixes a bug where it could attempt to decode with an unsupported codec if allow-profile-mismatch was set.

| | | | They are now unused.
* lavc: Remove register mechanism for hwaccelsMark Thompson2017-11-261-82/+0
| | | | | | | There is no longer any need for a list of them at runtime, because decoders now carry the pointers to their associated hwaccels internally. The file containing external declarations is now used to make the list of hwaccels for configure.

|
* lavc: Use hardware config information in ff_get_format()Mark Thompson2017-11-264-94/+211
| | | | | | | | | | | | | | | This removes the dependency that hardware pixel formats previously had on AVHWAccel instances, meaning only those which actually do something need exist after this patch. Also updates avcodec_default_get_format() to be able to choose hardware formats if either a matching device has been supplied or no additional external configuration is required, and avcodec_get_hw_frames_parameters() to use the hardware config rather than searching the old hwaccel list. The FF_CODEC_CAP_HWACCEL_REQUIRE_CLASS mechanism is deleted because it no longer does anything (the codec already contains the pointers to the matching hwaccels).
* lavc: Add hardware config metadata for decoders supporting hardware outputMark Thompson2017-11-2616-1/+372
| | | | | | | | | 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.

* avcodec/fft: fix INTERL macro on 3dnowMikulas Patocka2017-11-251-1/+1
| | | | | | | | | | | | | The commit b7c16a3f2c4921f613319938b8ee0e3d6fa83e8d ("x86: fft: Port to cpuflags") breaks the opus decoder in ffmpeg when compiling for 3dnow. The output is audible, but there's a lot of noise. The reason for the breakage is that the commit unintentionally changed the INTERL macro so that it is empty when compiling for 3dnow.

* | avcodec/nvdec: Round up odd width/height valuesPhilip Langdale2017-11-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nvdec will not produce odd width/height output, and while this is basically never an issue with most codecs, due to internal alignment requirements, you can get odd sized jpegs. If an odd-sized jpeg is encountered, nvdec will actually round down internally and produce output that is slightly smaller. This isn't the end of the world, as long as you know the output size doesn't match the original image resolution. However, with an hwaccel, we don't know. The decoder controls the reported output size and the hwaccel cannot change it. I was able to trigger an error in mpv where it tries to copy the output surface as part of rendering and triggers a cuda error because cuda knows the output frame is smaller than expected. To fix this, we can round up the configured width/height passed to nvdec so that the frames are always at least as large as the decoder's reported size, and data can be copied out safely. In this particular jpeg case, you end up with a blank (green) line at the bottom due to nvdec refusing to decode the last line, but the behaviour matches cuviddec, so it's as good as you're going to get.
