> I change OutPacketBuffer::maxSize to be 300000. The display of local RTSP client is correct. Unfortunately, the remote client’s display is still incorrect. Do you have any idea about this situation?

No, but because you're seeing problems only with a remote (networked) VLC RTSP client, I suspect you're seeing some network packet loss.  As I said before: "[You should not be sending] such ridiculously large NAL units.  You should reconfigure your encoder to encode each IDR picture (i.e., 'I-frame') into multiple 'slice' NAL units.  This is a good idea, because if packets forming a 'slice' NAL unit get lost, then that will cause only that slice to be non-renderable.  On the other hand, if the IDR picture is a complete NAL unit, then the loss of *any* packet will cause the whole picture to be non-renderable."
