The parser seems to cause latency issues when this happens (stuck for couple of seconds).
FYI - It was actually 2 pixels from top and 2 pixels from bottom. I found later on that the bitstreams from the camera itself was sparse, nothing to do with header parsing. I saw the feature request posted to FFMpeg about this from you.
