mencoder, new output containers via libavformat

[hellfred]

Just a update on mp4-output via mplayer.
An inititial muxer was added to libmpdemuxer (http://www1.mplayerhq.hu/cgi-bin/cvsweb.cgi/main/libmpdemux/muxer_lavf.c?cvsroot=MPlayer&sortby=date)
I do not know what the comitter aims for (just demuxing or muxing, too), if libavocoed is able to build correct mp4 files, if it will enable to mux to mp4 directly form mencoder and how fast the develpopmend of the muxer will progress. But the comitter can tell.

@hellfred: are you able to download anything from the mplayer CSV via the web interface? I always get an Error: Unexpected output from cvs co: cvs [checkout aborted]: Absolute module reference invalid error regardless of which file I'm trying to look at.

It is the same here, but with a cvs checkout i was able to obtain the file:

@edit: removed it again, the subsequent link works.

Seems to work ok if you edit the URL and remove "~checkout~/".

guys, i have to warn you that about the following with ffmpeg/libav .mp4 muxing:
1) it doesnt support avc in .mp4 muxing at all
2) it doesnt handle mpeg-4 asp b-frames muxing correctly
3) it doesnt remove packed bitstreams (dunno if mencoder writes those with xvid)
4) it doesnt remove the vol from every i-frame as often done for asp-in-avi (dunno how mencoder handles this)
5) i didnt test it extensively, so i dunno what other hidden bugs there might be

so practically this new output option will not really be useful if you aim at .mp4 :)

splitted this now to an own thread

once this is stable, it can become more very powerful :)
