Nope, input file. > PARSER -- (optional? or would this be a parser that I would write?) If required it just splits input into packets that are feed to demuxer. > BITSTREAM_FILTER -- This would filter an MPEG stream, yes?

That bitstream filter can not change frame flags like interlaced/top first etc... But you can change it after decoder with setfield filter. _______________________________________________ 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".
