Playlist support

[burek]

Would it be too difficult to add the playlist support in FFmpeg in such way that it would help replace using "for", "while" and other loops, in batch scripts? Here is an example of possible implementation:

ffmpeg -f playlist -i list.m3u -acodec copy -vcodec copy -f mp4 %1.new.mp4

This would have an effect of looping through the entire list.m3u file, reading each file from the playlist and remuxing it into mp4 format, saving it to a new file name, using a file name pattern (just like -f image2 does with "img%03d.png"), where %1 might represent the original file name.

I'm willing to make a patch for this enhancement, I just need a little push in the right direction. Which files should I look at, to edit them? I'll try to write it and submit the patch here.

This enhancement could also be used with ffplay, to play a playlist instead of one file.

I presume this was never implemented (yet)? I.e. ffmpeg *shouldn't* yet work for
$ ffplay -i  http://audio-ogg.ibiblio.org:8000/wcpe.ogg.m3u
?

(for followers, in the meantime you can just parse m3u files manually:  http://ffmpeg.gusari.org/viewtopic.php?f=12&t=614)

Doesn't this work with the concat demuxer?

Playlist syntax (not just for m3u but for pls and others is different) and concat
demuxer added probing for different signature from m3u8, but code from concat could be used/base for playlist "demuxers"
