<p class="owapara"><span style="font-family:"Calibri",sans-serif;color:black">We use live555 to receive video and audio RTSP streams from cameras (and we show the video in our application). Our solution worked well for older Axis cameras, but it doesn't work
for newer Axis cameras, which firmware is 5.6 or later.<o:p></o:p></span></p>
<p class="owapara"><span style="font-family:"Calibri",sans-serif;color:black"> <o:p></o:p></span></p>
<p class="owapara"><span style="font-family:"Calibri",sans-serif;color:black">The problem is that the stream stops after 1 minute. This is the typical timeout, so camera most probably doesn't get/accept the keep alive message. Note that I use the onvif RTSP
stream (rtsp://[ip]/onvif-media/media.amp).<o:p></o:p></span></p>
<p class="owapara"><span style="font-family:"Calibri",sans-serif;color:black"> <o:p></o:p></span></p>
<p class="owapara"><span style="font-family:"Calibri",sans-serif;color:black">Some days ago I downloaded 2015.05.31 version of live555 library and I built testRTSPClient and did tests with this. It ran for 30 minutes for our old camera (then I stopped it),
but it stopped after 1 minute with the new Axis camera (firmware 5.6).<o:p></o:p></span></p>

<p class="owapara"><span style="font-family:"Calibri",sans-serif;color:black">I also tried VLC with the same stream, it worked well after 1 minute. I also tried to modify my code, and send OPTIONS command in every 10 seconds, and that also worked. Maybe VLS
do similarly.<o:p></o:p></span></p>

<p class="owapara"><span style="font-family:"Calibri",sans-serif;color:black">Do you have any idea what can be the problem? Is it an Axis firmware problem?<o:p></o:p></span></p>
