Webrtc record stream

Hi there,
One question. I am using a tapo c310 cam and i added it in Homeassitant with the tapo cam control.
Also i added it in WebRTC to get sound.
Now i am using an automation to send me a pic and in rare cases also a video. This works fine for tapo recordings, but it seems that i cannot record a video from the WebRTC Stream. With WebRTC i have only available:
WebRTC Camera: Create Link and
WebRTC Camera: DashCast

Has anyone else recorded a stream from WebRTC?
