<div>Hi All,</div>
<div> I have written an RTSP server (runs either on windows or linux) to serve real time video and was testing with MPlayer and VLC rtsp clients. While Mplayer plays the video fine, vlc doesnt persistently play the same stream, just shows a few frames in the beginning, then freezes.
</div>
<div>The log spits out messages like: </div>
<div> </div>
<div>"ffmpeg decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?)"</div>
<div> </div>
<div>What could be the issue? My first guess was the RTP timestamp but I verified that I am sending the milliseconds elapsed since system startup at the time when a frame is seen</div>
<div>correctly, so for a 30 fps stream, the timestamp increments by about 33 (using windows high performance counter)</div>
<div> </div>
<div>The problem happens on linux as well which uses gettimeofday. </div>
<div> </div>
<div>Anybody have gotten any clue as to whats going on?</div>
