Comment 1 Dongxiao Xu 2010-12-29 23:25:47 UTC 
the r416 version of libowl-av caused this issue, which uses playbin2 instead of
playbin.

I doubt whether there are usage difference between the two playbins? Orignally
libowl-av should be designed with playbin operations.

One choice is that we can change back to the previous r398 commit.

Also BUG 615 should be the same problem with this one.

CC Edwin who owns libowl-av.
Comment 2 Edwin Zhai 2011-01-12 21:46:15 UTC 
Seems playbin2 has some bug, don't know if it got fixed now.

So, dongxiao can you have a check with current upstream? If it still be there, I can revert the libowl-av upgrade and lower the priority of this bug.

Is it okay.
