[gst-devel] gst-launch and AVI file with only good plugins

[Vinay]

Hello Vinay,

>From the stream properties, it looks like the audio data is in
uncompressed format. But the pipeline that I mentioned uses "mad"
which is an mp3 decoder. Can you modify the audio pipeline path and
try out?

Also, you can try with ffdemux_avi if avidemux does not work.

Regards,
Vinay K.
