Hi, how do you count the number of decoded frames? Feng normally fixed this issue and this was propagated to git master branch.

we add "printf("  %s, %s, %d\n", __FILE__, __FUNCTION__, __LINE__)" in the
function "vaPutSurface", i.e., play a 50-frames MP4 file with gst-launch, and
there are less than 50 vaPutSurface print in log.

but still can be reproduced in qa branch.
