1 year ago This does not appear to be an upstream bug in ffmpeg. The h264 decoder is listed as having videotoolbox hwaccel support on this hardware.
Eh, I'm not convinced. The hardware does claim to have VideoToolbox support, but so we try to use it and it fail to decode our test frame. I believe someone has reported this issue before on similarly ancient AMD hardware.
