I.MX53 reverse video playback

Hello,

 

I have a requirement to play video in reverse through the VPU on the i.MX53. The video is MJPEG format. I'm manually reordering the stream, frame by frame, then copying to the VPU bitstream buffer. This technique is working, but it skips and freezes frequently. I get the warning "Incomplete finish of decoding process" when things go wrong. I've been trying to get more detailed information about the problem, but haven't had much luck.  I wanted to see if anybody else has done this before and if there are better techniques to use, or if anybody has any suggestions for getting more details from the VPU beyond the data returned by vpu_DecGetOutputInfo.

 

Thanks in advance,

 

Paul
