[Live-devel] Proxy server - stop stream from back-end if there are no viewers

[Saskia van Emst]

Hi Ross,

Thanks for the reply. I checked in verbose mode and the Hikvision camera does send 'Option not supported' (removed authorization bits):

ProxyServerMediaSubsession[rtsp://---:554/h.264/ch2/sub/,H264]::closeStreamSource()
Sending request: PAUSE rtsp://---:554/h.264/ch2/sub/ RTSP/1.0
CSeq: 6
Authorization: Digest username="---", realm="---", nonce="---", uri="---", response="---"
User-Agent: ProxyRTSPClient (LIVE555 Streaming Media v2016.05.20)
Session: 1248619613

Received 111 new bytes of response data.
Received a complete PAUSE response:

CSeq: 6

However in the OPTIONS response, PAUSE is listed:

Sending request: OPTIONS rtsp://---/h.264/ch2/sub/ RTSP/1.0
CSeq: 4
User-Agent: ProxyRTSPClient (LIVE555 Streaming Media v2016.05.20)

Received 153 new bytes of response data.
Received a complete OPTIONS response:
RTSP/1.0 200 OK

Any ideas what could cause the PAUSE command not to work while it is listed? Also I did note the time of the camera is off, could this cause a problem?

Afterwards I changed sendPauseCommand to sendTeardownCommand in ProxyServerMediaSession.cpp, and this does work. Of course then when I try to access the stream again there are problems because the proxy tries to resume a session which is unknown to the camera, etc..

The camera firmware has been updated not too long ago, I'll try to see if there is a new version.

Best regards,
Saskia
