Upgrade Web Video SDK v1.2.0

We have faced issues after upgrading to Web Video SDK version 1.2.0.
As soon as we start a session, the video gets frozen immediately.
Audio cracks hardly or is not working at all.

Hey @muellseb

Thanks for your feedback.

Could you test with our sample-app, will the same problem occur?


Hi @vic.yang

no i did not.
I already updated to SDK version 1.2.3 after I have seen your changelog.
The issues are fixed with that version.

  1. Audio and video not reconnecting properly on failover
  2. Known issue with the video stops playing and goes black when resolution changes to or from 720p

Now I am facing another issue.

User 1 joins a session and switches on the camera.
User 2 joins the session.
Everything is rendered correctly.

User 2 leaves the session and re-joins.
The dimensions are calculated correctly. But the video of User 1 takes the whole size of the canvas with the video. The avatar dimensions are correct.

When I resize the window, the video is adjusted to the correct dimensions.

any idea?

@vic.yang @tommy

I made the very same experience in the sample app.
Seams like a bug.

User 1 joins and switch on camera

User 2 joins and everything is fine so far.

user 2 refreshs the browser.

user 2 joins again.


Hey @muellseb

There are some issues with the sample-app, we left out the logic to reset the mediaState when leaving the session, so next time when joining the session, the isVideoDecodeReady is falsely treated as true, but actually, it is false. We have updated the sample app, you can check the change.
