All of those look like bitstream features. None of them you could change without re-encoding or a specialized tool that can parse and alter the bitstream. Metadata (as ffmpeg calls it) is tags, like artist and track details on a music file. Plus some other things, like chapters. To edit those software need only understand the container or file format. You probably cannot get the things you mentioned elevated into metadata in ffmpeg because they are only known by separate parts, namely libavcodec and libavformat. _______________________________________________ ffmpeg-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
