Encoding from wrong start position

What is the encoder you are using ? Is it H264 or MJPEG.

For H264 encoder a bug fix is required in encLink to consider runtime startX,startY change.Patch is below.

For MJPEG it requires migration to newer MJPEG encoder version as the codec has a bug and startX,startY is not considered when encoding.
