forcing ffmpeg's file level concatenation demuxer

Hey all,

I'm currently trying to write/test a plugin for comedy central and I've got the writing part down, however, in order to comfortably view the episodes, which are cut into several mp4(h264/aac) segments, i'd need to have "-f concat" appended to ffmpeg's command line (outside of the url parameter).

See this post for more information/syntax: http://stackoverflow.com/a/11175851.
  • the concat protocol won't work because mp4 can't be concatenated at file level,
  • the video filter would require adding a lot of other parameters, and
  • the concat demuxer is probably the cleanest solution with the lowest overhead/error-proneness.

Any way of making this happen? Segmented video is pretty common on the internet for advertising/storage reasons.


On a sidenote: My solution would have been to have the plugin create temporary files using File.createTempFile() containing the "file '<url>'" syntax. If someone happens to have a better, portable solution, I'd be quite happy to hear it.

It's currently not possible. I'm going to be working on some concat tickets for local files for 1.5, maybe it could be reused there.
