Thanks for response. Following article says that Chrome supports only up to 1080p resolution in getUserMedia.
Any idea or comments how to achieve transmission of 4K?
getUserMedia is a media device operation, which is quite different from the streaming data transmission. Regarding our MCU server, we'd like to support various video streams, not ONLY the typical webrtc stream from GUM, but also other streams, like RTSP/RTMP/etc.
Transmission of 4K is not a hard thing, but the bandwidth and playback quality (which depends on client machine configurations) might mostly become problems.
