[BUG] kvsWebrtcClientMasterGstSample ' s video delay is very high compared to audio

Open kabosy620 opened this issue 3 years ago • 0 comments

When I executed below sample app and launch "KVS WebRTC Test Page"'s Viewer, ./kvsWebrtcClientMasterGstSample test_channnel audio-video testsrc

"chrome://webrtc-internals" shows a video latency of about 4 sec. On the other hand, audio latencyis less than 100ms. （Please refer to the attached image.）

When I set video-only argument , video latency is very law.

when connecting USB camera and remove the testsrc argument, the symptoms were the same.

A similar issue has been posted on stack overflow. https://stackoverflow.com/questions/72044633/fix-audio-video-sync-on-aws-kinesis-stream-gstreamer-on-rapsberry-pi

Master Device is RPi4 (Raspbian GNU/Linux 10 (buster)

SDK Ver is v1.73

Enabling or disabling TURN had no effect on latency.

Please Confirm.
