This has been tested using version 2013-01-03 of the LIVE555 libraries with zero modifications. Here are steps to reproduce:<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span style='mso-list:Ignore'>1.<span style='font:7.0pt "Times New Roman"'> </span></span><![endif]>Set QuickTime to use HTTP as the transport.<o:p></o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span style='mso-list:Ignore'>2.<span style='font:7.0pt "Times New Roman"'> </span></span><![endif]>Launch testOnDemandRTSPServer.exe<o:p></o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span style='mso-list:Ignore'>3.<span style='font:7.0pt "Times New Roman"'> </span></span><![endif]>Use QuickTime to connect to one of the streams served by the testOnDemandRTSPServer.<o:p></o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span style='mso-list:Ignore'>4.<span style='font:7.0pt "Times New Roman"'> </span></span><![endif]>Pause the stream in QuickTime.<o:p></o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span style='mso-list:Ignore'>5.<span style='font:7.0pt "Times New Roman"'> </span></span><![endif]>Kill and restart the testOnDemandRTSPServer.<o:p></o:p></p><p class=MsoListParagraph style='text-indent:-.25in;mso-list:l0 level1 lfo1'><![if !supportLists]><span style='mso-list:Ignore'>6.<span style='font:7.0pt "Times New Roman"'> </span></span><![endif]>Play the stream again in QuickTime.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>It seems that after following this sequence, QuickTime will send a POST as the first command to the RTSP server. If this happens, the server crashes due to fOurServer.fClientConnectionsForHTTPTunneling being NULL in handleHTTPCmd_TunnelingPOST. The attached patch simply creates the fOurServer.fClientConnectionsForHTTPTunneling the same way handleHTTPCmd_TunnelingGET does. With the patch applied, the server returns a 405 error to QuickTime and the whole conversation can be retried.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If this is not the correct way to fix this issue please let me know, as this is easy for me to reproduce and I can test a different fix if necessary.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Chris Richardson<o:p></o:p></p><p class=MsoNormal>WTI<o:p></o:p></p></div></body></html>
