Screenshare jumps #76

Closed vvedharaju closed 4 years ago

vvedharaju commented 4 years ago

Describe the bug

When a screenshare stream is being published by a host for some audience members the screen share experience is not smooth.

  1. On every slide change, the slide gets a bit blurry and then looks clear.
  2. Sometimes when the slide changes, there's a flash of the previous slide before it stabilizes on the next slide.

We are using the 720p_1 profile for screen share. We are also using optimizationMode: 'detail' for screenshare.

Sorry for that. We have identified the problem, which is caused by a detail priority related parameter of WebRTC. It will be fixed in the next version.

vvedharaju commented 4 years ago

@HAHAHA44 is there anything I can do in the meantime to get a better experience?

vvedharaju commented 4 years ago

@HAHAHA44 Also when will the next version be released? Is it possible to have a hotfix version for this since I'm sure this will affect production apps.

FarazPatankar commented 4 years ago

Curious about a temporary fix for this as well. Would removing the optimizationMode setting help in the meantime? Also, any ETA on the fix?

vvedharaju commented 4 years ago

@HAHAHA44 any workaround in the meantime?

vvedharaju commented 4 years ago

@HAHAHA44 any update on this?

vvedharaju commented 4 years ago

@HAHAHA44 is this resolved?

HAHAHA44 commented 4 years ago
  1. optimizationMode: 'detail' is useful.
  2. use vp8 codec.
  3. Do not replace a videoTrack to screenShareTrack, there are a bug of chrome that will fix the send bitrate to a low value.

@HAHAHA44 issues resolved after switching to vp8 👍 thanks
