However, that's probably not the cause of your problem.<br><br>Sorry, but I don't know what's causing the delay that you're seeing. Are you *sure* that there is a ~1 second delay between each call to "FramedSource::afterGetting()" and the *next* call to "doGetNextFrame()"?<br>-- <br><br>Ross Finlayson<br>Live Networks, Inc.<br><a href="http://www.live555.com/">http://www.live555.com/</a><br>_______________________________________________<br>live-devel mailing list<br>live-devel@lists.live555.com<br>http://lists.live555.com/mailman/listinfo/live-devel<br></div></blockquote></div><br></div></body></html>
