OR [h264_videotoolbox @ 0x7f9709149600] Transfer function smpte2084 is not supported. This is triggered from FFmpeg here https://github.com/FFmpeg/FFmpeg/blob/98478c05edb674ec429c298fbe593bda493ba6... It would be nice to add the transfer function smpte2084 to videotoolboxenc.c, which has the constant name kCVImageBufferTransferFunction_SMPTE_ST_2084_PQ https://developer.apple.com/documentation/corevideo/cvimagebuffer/image_buff... -- Ticket URL: <https://trac.ffmpeg.org/ticket/7953> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
