[gst-devel] Does ffmux_mov support muxing both audio and video?

[Deeptendu Bikash]

Hi Edward,

Thanks for your help.

I found out that my pipeline was actually muxing both audio and video,
despite gstreamer giving that error. Also gstreamer playbin itself was not
capable of playing the movie. VLC player could play it, though it got the
duration wrong. Quicktime could not play it. So I guess it again boils down
to the bug/s in ffmpeg regarding handling audio duration which we discussed
in another mail thread. So let me start looking into it.

Once again, I really appreciate your help.

Regards,
Deeptendu
