There may be a timestamping problem, or this computer is too slow.

the video output is discontinuous。

I find different framerate frame,as 15、20、24、

but the imx53 received stream framerate is always 30.

I copy the mp4 file to sd card, imx53 could get correct framerate.

Actually only 30 fps is accelerated by the hardware.

So it is the only possible framerate.

Have a great day,
