How to stream higher resolution than 1080p?

OpenVidu v2 Issues developing apps
1

Has anyone been able to stream higher than full hd video and with what kind of setup and settings? I have tried to stream 4K (publisher resolution: set to ‘3840×2160’) from firefox windows to firefox mac and when I check the resolution on receiver side is 1920x1080. With 4096x2048 publisher resolution I didn’t manage to broadcast at all. With 2560x1440 resolution the result is 1440x810 according to about:webrtc.

The documentation mentions high quality resolution as 1280 x 720, however 1920 x 1080 resolution works fire. https://docs.openvidu.io/en/2.14.0/api/openvidu-browser/interfaces/publisherproperties.html#resolution

Could this problem resolve if I used mediasoup instead of kurento?

Mediasoup is a more lighweight SFU than Kurento, so it is possible 4K can be managed using mediasoup.

We have not tested ourselves, but it seems it is possible without issues:

If you test it, please share the results with the community.
