The playback is not smooth in the beginning. Every time, when the video resumes after pause, the playback must be not smooth. I use a traffic sniffer tool (e.g. WireShark) to analyze the incoming packets and found that the sending speed from server in the beginning is much higher than the stream bitrate. Therefore, the more pause and play are sent, the more packets are queued.</span></font></div></div></div></span></blockquote><div><br></div></div>This is unlikely to be a problem with our software. (The best way to verify this is to use "openRTSP", rather than VLC, because openRTSP is 100% our software.) Our software - as used in VLC - only receives incoming RTP packets; it does not decode or render them.<div><br></div><div><div>If the server is sending data more rapidly than it should, then that's a problem with the server, not the client.</div></div><br><br><div>
