#1571: Make "concat" muxer/demuxer which will act like "image2" -------------------------------------+------------------------------------- Reporter: burek | Type: Status: new | enhancement Component: | Priority: wish undetermined | Version: Keywords: | unspecified Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- Since a lot of people are trying to use ffmpeg to concat their media files lately, it would make sense to maybe create a muxer/demuxer that will act like image2 mux/demux, which would read several input files, one after another (like a playlist) and would produce a useful output for filters/encoders further in the processing chain. Showcase: {{{ ffmpeg -f concat -i "input1:input2:input3" -acodec .. -vcodec .. output }}} -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/1571> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker
