detecting ip camera video lost

[Kocsis Tibor]

Hi,

my problem is the following: I watch a live view from an ip camera
through rtp, the source element is rtspsrc. Then I pull out the
camera's utp cable and I don't see any error messages on the bus or
something else from that I can detect the pull-out. Is there any way
to detect the video lost after all? What should I do?

Thanks,
Tibor

I guess for "UTP" cable you mean the ethernet connection (being usually the connection toward the physical camera coaxial).

In order to understand whether no data is neing transmitted anymore, you can use the "on-timeout" signal in rtpbin:

http://www.gstreamer.net/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-gstrtpbin.html#GstRtpBin-on-timeout

Unfortunately, this timeout value appears not to be directly tunable, being computed as the minimum between 5s and 5 times the (RTCP?) reporting time. The latter is not directly tunable and should require some negotiation at signaling level (I guess you're using RTSP or SIP) to get prompt reaction for the receiving sw.

Regards

Thanks,
