[gst-devel] Possible bug on ffmux_mp4

Hi all,

I am trying to generate a mp4 file using:
$ gst-launch-0.10 -v ffmux_mp4 name="mpg" ! filesink
location="/tmp/output.mp4" gnomevfssrc location="/tmp/sample.nuv" !
decodebin name="d" { d. ! queue ! videorate ! videoscale !
"video/x-raw-yuv, width=(int)320, height=(int)240" ! ffmpegcolorspace
! ffenc_mpeg4 ! "video/mpeg,mpegversion=4" ! queue ! mpg. } { d. !
queue ! audioconvert ! audioresample ! faac ! queue ! mpg. }

The generated file plays fine with mplayer (sound and video) but when
trying to play it with gstreamer (totem, gst-launch playbin ...) there
is no sound.

If I generate using:
$ ffmpeg -i /tmp/sample.nuv -s 320x240 -vcodec mpeg4 -acodec aac /tmp/output.mp4
it works both on gstreamer and mplayer.

I heard that ffmux_mp4 was buggy, does anybody knows what is the
problem with it, so I can try to fix it?

Any help is appreciate
