Hi Kris,
I have already tried to replace caps as you advise to me, but rtsp-server return the same error.
I tried all combinations:
- caps=\"application/x-rtp,media=(string)video,encoding-name=(string)H264\"
- caps=application/x-rtp,media=(string)video,encoding-name=(string)H264
- caps='application/x-rtp,media=(string)video,encoding-name=(string)H264'
but nothing change.
Hi,
