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

Mark Thompson	d06aa24ba5	hwcontext: Hardware frame mapping Adds the new av_hwframe_map() function, which allows mapping between hardware frames and normal memory, along with internal support for implementing it. Also adds av_hwframe_ctx_create_derived(), for creating a hardware frames context associated with one device using frames mapped from another by some hardware-specific means.	8 years ago
