Also on desktop with same version of Gstreamer I am able to play with sync. In this particular case the video is being played very fast and audio is not able to catch up with the DMAI based plugins. I filed the same as bug on OMAP-Zoom, but thought if I could get some quick pointers to this issue, it would be helpful. I have one more query with respect to the video encoder in Dmai based plugins. Two experiments are done with TiVidenc and there results are also provided below. Both are failing with same error.This was from latest revision r121.
