gstreamer stops playing the media content

akshat
Hello,
I am using gstreamerSDK(v0.10.6) on windowsXP. I am trying to play an .avi file but it stops playing the content within few seconds and does not play the file completely.
I appreciate   your help.

Thanks
Akshat

Re: gstreamer stops playing the media content

Martin.cheng
first of all, you should used gst-launch in CMD to try if the pipeline woks or not
if so, I guess there 's something problem with decoder
As I counter this kind of situation like freezing, There must have been wrong with decoder, check it
