Something my team has been worried about these weeks:
https://trac.ffmpeg.org/wiki/HWAccelIntro <https://trac.ffmpeg.org/wiki/HWAccelIntro>
Notice it says explicitly:
VideoToolbox ¶ <https://trac.ffmpeg.org/wiki/HWAccelIntro#VideoToolbox>
VideoToolbox <https://developer.apple.com/documentation/videotoolbox>, only supported on macOS. H.264 decoding is available in FFmpeg/libavcodec.
Is that a typo: should it read macOS and iOS OS ?
Or is it literally only on Mac version?
(1) note the top chart “Platform API Availability" suggests both.
(2) note however the second chart “FFmpeg API Implementation Status” says:
VideoToolbox:Decoder:Standalone is ”N”
However, I do not know what “Standalone” means under FFmpeg-API
(We are using all of FFmpeg, the latest, compiled in to C, for use in iOS.)
