WebRTC transmission of high-resolution issues

Hi, I am transmitting an image with a resolution of 2800*1752 using WebRTC, and the frame rate drops to 20fps even when my screen is empty.

I noticed that the Video Stream Out node is consuming most of the performance, and when I lock opviewer1, the program returns to 60fps. Is this normal? Thanks！

Hi @tianzhuo,

the webrtc video stream currently does not support hardware encoding, so most likely you are seeing this because of the heavy cost on the CPU encoding the video.

We are working on a solution for this though.

cheers
