[Mesa-dev] [st/omx/dec/h264] Handing negative POC

[Namburu, Chandu-babu]

Hi ,

I have been working on an issue where the for a particular stream playback is stuttering and there are lot of frame drops.

That particular stream has negative POC value and as POC value is treated/read as unsigned, the frame is getting flushed out of DBP at the end of GOP instead of at starting.

Fixed this issue by considering POC as signed value instead of unsigned. Attached the patch, please review.
Regards,
Chandu
