hi,
Can you just explain in brief, watz the problem you are facing with ffmux_asf.If you explain with the pipeline i would be more clear.

There are 2 muxer plugins for asf.
1)ffmpeg's ASF muxer (ffmux_asf)
2)There is gstasfmux.c file in gst-plugins-ugly and gst-plugins

In the second approach you need to port the .c file to the current gstreamer.

Porting of these .c file to gstreamer would be appreciated,

Regards,
Irfan

hi,

asf plugin code (in gst-plugins-ugly) has a muxer that could be ported
to 0.10. Reusing ffmpeg components seems to be a bit tricky.
