Hi,

Because -o use H264 frame, desktop capture is not compressed. You need to find a way to compressed it.

Is webrtc streamer currently using the H264 codec or VP8？？？

mpromonet commented 1 year ago

Hi,

Using -o, only h264 is added to supported codec. Without it supports codec supported by webrtc, h264, vp8, ans others... You Can sée this in the /call answer.

Best Regards Michel

I want to share video conference screens with you, but now the CPU takes up a large proportion. I want to use less than 3% of the CPU. Is it the only way to add gpu hard coding? - o supports rtsp, but does not support screen sharing？ Can desktop capture be forwarded directly using -0?

thank you
