Hi chip experts,


Sometimes i.MX53 VPU_API returned following values then decoding process lost.

indexFrameDecoded = -1 #EOS not detected or skipped

indexFrameDisplay = -3 #decoder couldn't provide output


     where VPU_API = int indexFrameDisplay; or int indexFrameDecoded;

     See Page36 DecOutputInfo of i.MX5x_Linux_VPU_API.pdf

Is there any idea how to debug this issue?      e.g. set breakpoint somewhere in VPU_API


Can anyone help me ?
