FFmpeg 4.1 (as per the changelog) https://github.com/FFmpeg/FFmpeg/blob/master/Changelog does support decoding S12M timecode in h264. Circling back to the original question(s) with your additions above: 1. Can h264_nvenc be likewise configured to emit the equivalent "s12m timecode(s)" with a similar option as the av1 & hevc_nvenc encoder wrappers? 2. Is pic timing SEI signalling implemented in h264_nvenc? _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
