Snapshots and DVR of WebRTC AV1

[Diras226]

Hey guys,
i want to use AV1 WebRTC stream and i learned that rtc_to_rtmp is not possible by now. As a result it is not possible to use the dvr and snapshot features. I wonder is there any chance to get at least a snapshot of the WebRTC stream by another method. I would love to hear from you, if you have any ideas how to accomplish it.

Thanks in advance,
