However, that’s only a partial fix since although the source is now delivering samples with no errors, the graph is not rendering them (and I have no idea why not).<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I am quite experienced in DirectShow, but this is my first time with Live555.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I’ve got two requests, really. Firstly, has anyone got this to work properly or can they recommend an alternative (open source) which works reliably.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Secondly, the documentation for Live555 is a touch on the light side, however I have found some references to tutorials (<a href="http://www.mail-archive.com/live-devel@lists.live555.com/msg00238.html">http://www.mail-archive.com/live-devel@lists.live555.com/msg00238.html</a>), however the referenced link does not appear to exist anymore. Does anyone have a copy of this.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Allied to that, I can more or less see how the RTSP control stream works, but I can’t figure out what it is that starts the communication to receive any RTP or other payload.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Any assistance would be VERY gratefully received.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Iain<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='mso-fareast-language:EN-GB'><img border=0 width=307 height=95 id="Picture_x0020_1" src="cid:image001.gif@01CB6641.7A521C20" alt="Description: iain-downs-logo"><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;mso-fareast-language:EN-GB'><o:p> </o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-GB'>01423 872988 - <a href="http://www.idcl.co.uk/">http://www.idcl.co.uk</a><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;mso-fareast-language:EN-GB'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;mso-fareast-language:EN-GB'>Iain Downs Consulting Limited is registered in the UK with number 329446<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:8.0pt;mso-fareast-language:EN-GB'>at The Old Coachhouse, Rear Eastville Terrace, Harrogate HG1 4HJ<o:p></o:p></span></p><p class=MsoNormal><span style='mso-fareast-language:EN-GB'><o:p> </o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
