[gst-devel] Why audio extract on flv won't preroll?

[Shawn McMurdo]

Nobody knows?
Can anyone at least comment on whether my pipeline is correct?
Thanks!
Shawn

Hi,
I am trying to do an audio extract on various types of videos.

Using decodebin as shown below on this video:
http://www.shawnim.com/ax/balboa.flv
causes gstreamer to hang in the preroll.

The same pipeline works on other flvs and wmvs.
Can anyone explain why this is happening?

I am running gstreamer 0.10.24 on Fedora 11 (2.6.29.6-217.2.16.fc11.x86_64).
The pipeline I am using is:
gst-launch-0.10 -m -t -v filesrc location=$1 ! decodebin ! audioconvert ! audio/x-raw-int,channels=1,width=16,depth=16 ! audioresample ! audio/x-raw-int,rate=16000 ! wavenc ! filesink location=$1.wav

The output from running this pipeline is:
http://www.shawnim.com/ax/balboa.out

BTW, decodebin2 works on this file but seems to have trouble with other files.
Any explanations or pointer appreciated.
Thanks.
Shawn
