Hi Sivagamy,
Thanks for your reply! The VCODEC_BITSBUF_S struct has encodeTimestamp and timestamp members. I know the encode link set the encodeTimestamp after the encode has done. In my usecase, when I filled the input video frame to the emptyBufList get from deocde link, I set the lowerTimeStamp and upperTimeStamp base on the frame count and frame interval. I don't know if the decode input buffer and encode output buffer are actually the same so that we can get the time delay of the data process through pEmptyBuf->encodeTimestamp - pEmptyBuf->lowerTimeStamp?
