I used i.Mx53 QSB.
When I typed command: gst-launch playbin2 uri=file:///opt/eric/2.avi, the video played good.
However, when I typed command: gplay /opt/eric/2.avi, it printed 'playbin is employed!' and played for only 8 seconds then stopped. It is the same as using command 'gst-launch playbin uri=file:///opt/eric/2.avi'.
My question is how to make gplay use palybin2 and print 'playbin2 is employed!'.
