AV_PKT_DATA_PRFT side data might be the right tool for you. > I hope this mailing list is appropriate for my question, otherwise please > forgive me. It is only appropriate for this mailing list if you want to improve FFmpeg itself (i.e. by making the hls muxer use AV_PKT_DATA_PRFT; the dash muxer already seems to use it). If not, the user mailing list is the right place. - Andreas _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
