I am trying to send audio to the camera speaker trough RTP like the camera is sending audio packets to me. I use www.onvif.org/ver20/backchannel in the RTSP requests and the camera aswers me with 200 OK so I assume she does support backchannel, but I get only 1 control for audio when DESCRIBE is sent.
Is these some way to send audio to the camera speaker at all? And how - HTTP/RTSP? And please give some specification
PS
I have managed to send audio data to the camera trough HTTP, but still the question remains:
Can audio be sent to the camera with ONVIF specification?
