H264 transmission, too high CPU usage #209

Closed neucoreAn closed 5 years ago

Running on ARM, the CPU takes up 70% of the total. It converts H264 into webrtc. Now can we directly transmit H264 data?

Hi neucoreAn, This question was often asked, actually the WebRTC SDK seems to need I420 frames, but maybe you could try to feed the rtc::VideoBroadcaster with an H264 frame ? or modify the WebRTC SDK to process H264 frames. An project that forward RTP packet without uncompression/compresion is janus-gateway Best Regards, Michel.
