I can confirm that GStreamer used in the Axis 5.60 cameras does *not* honour RR packets to show a live connection. I have raised this with them as it's a change of behaviour and is contrary to their documentation but they couldn't reproduce it. They do have packet captures showing the behaviour though and will investigate further.
Our solution was to send a null GET_PARAMETER request at 5s short of the timeout specified in SETUP response (accessible through rtspClient->sessionTimeoutParameter()). Note that this behaviour is mimicked by VLC. -- Deanna Earley | Lead developer | icatchercctv w: www.icode.co.uk/icatcher<http://www.icode.co.uk/icatcher> | t: 01329 835335 | f: 01329 835338 Registered Office : 71 The Hundred, Romsey, SO51 8BZ. Company Number : 03428325 From: live-devel [mailto:live-devel-boun...@ns.live555.com] On Behalf Of Adrian Kovacs Sent: 03 June 2015 15:48 To: live-devel@lists.live555.com Subject: [Live-devel] Axis firmware 5.6 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. 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). 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). 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. Do you have any idea what can be the problem? Is it an Axis firmware problem? Adrian Kovacs
