Webrtc frame skipping #789
Comments
|
Just a quick update there is nothing in the chrome debug stats outside of: total freezeduration 21.141 I have ruled out any network or transport related issues. MSE/Websocket is buttery smooth. No dropped frames are detected |

You should try to use go2rtc addon. I can see that WebRTC works for you via TCP. This is strange because for LAN connection it should be UDP. Maybe problem related to port forwarding for Frigate docker container. |

Its weird using firefox it uses UDP

And also has problems? What's the bitrate of the stream? |

When using version v1.8.4 I have UDP mapped yet it uses TCP? Why ?
On the default version it uses UDP no problem with the same docker settings

Bitrate is 8192 Kb/Sec @ 3840*2160

This is hi bitrate and can be a problem real time streaming for WebRTC |

bug

I'm seeing similar behavior but on both MSE and WebRTC. I tried to disable audio transcoding as well but no change. My streams are transcoded to H264 (from H265 of camera) by go2rtc. To avoid any other posssibilities, I'm testing using go2rtc web interface on port 1984 using "stream" link to test. All my 4K streams are stuttering like this, skipping frames on both MSE & RTC. On the exact same device, ie a Chromebook or a PC, if I launch VLC and point it to the RTSP stream of go2rtc, like rtsp://go2rtc_ip:8554/Cameraname then it plays flawlessly. |
Im seeing some weird behaviour using webrtc where I get frame skipping / stuttering every 2 seconds.
The issue isnt present when using mse whatsoever. Ive tried the default Frigate version of go2rtc and also updated to 1.8.4 with no change.
