Author	SHA1	Message	Date
Marvin Scholz	b4f9fcc63c	avutil/hwcontext_videotoolbox: Update documentation ... The documentation was not clear at all what specifically the function does, so it was left unspecified if it will unset or not touch attachments it could not map from the AVFrame. The documentation of the return value was wrong as well. Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>	6 months ago
Zhao Zhili	5d255ba95a	avutil/hwcontext_videotoolbox: add frame hwctx to specify color range ... VideoToolbox use different identifiers for the same pixel format with different color range, like kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange kCVPixelFormatType_420YpCbCr8BiPlanarFullRange. Before the patch, vt_pool_alloc() always use limited range, and it will fail for pixel format AV_PIX_FMT_BGRA since there is no limited range kCVPixelFormatType_32BGRA.

rcombs	69bd95dcd8	lavu/videotoolbox: expose conversion routines for color parameters ... Also fixes symbol lookup errors on older macOS when built with a newer SDK, introduced in 6cab5206b0	3 years ago
Aman Karmani	504c60660d	avutil/hwcontext_videotoolbox: implement hwupload to convert AVFrame to CVPixelBuffer ... Teach AV_HWDEVICE_TYPE_VIDEOTOOLBOX to be able to create AVFrames of type AV_PIX_FMT_VIDEOTOOLBOX. This can be used to hwupload a regular AVFrame into its CVPixelBuffer equivalent. ffmpeg -init_hw_device videotoolbox -f lavfi -i color=black:640x480 -vf hwupload -c:v h264_videotoolbox -f null -y /dev/null Signed-off-by: Aman Karmani <aman@tmm1.net>	3 years ago

wm4	f0435bbe17	hwcontext_videotoolbox: fix fate-source ... Thanks to James Darnley for figuring out what the hell it wanted.	8 years ago
wm4	532b23f079	videotoolbox: add hwcontext support ... This adds tons of code for no other benefit than making VideoToolbox support conform with the new hwaccel API (using hw_device_ctx and hw_frames_ctx). Since VideoToolbox decoding does not actually require the user to allocate frames, the new code does mostly nothing. One benefit is that ffmpeg_videotoolbox.c can be dropped once generic hwaccel support for ffmpeg.c is merged from Libav. Does not consider VDA or VideoToolbox encoding. Fun fact: the frame transfer functions are copied from vaapi, as the mapping makes copying generic boilerplate. Mapping itself is not exported by the VT code, because I don't know how to test.	8 years ago
