[gst-devel] Audio/Video timing problem

[Steve Brown]

I inserted/altered some info messages in oss and xvideo.

They show that the sound seems to be play about 650 to 750 ms early. The 
video looks pretty close.

Attached are the diffs to the info output of the current cvs. I used 
gst-play with gst-info-mask=0x000e0000 and AlienSong.mpg

Anybody have an idea what is wrong.?

Steve
