How can I solve the quality issues of screen sharing on Web clients?

Problem

When a Web client shares the screen, the screen freezes or blurs.

Find the solution that corresponds to the version of the Web SDK you are using.

Troubleshoot the problem by following the steps below:

Ask the user to use the latest official version of the Chrome browser on desktop.
Set codec as vp8 when calling createClient.
Check whether the user is sharing an application window.
- If so, ask the user to share the browser tab or the entire screen instead.
- If not, check the encoding configurations you set in setScreenProfile.
Upgrade the SDK to 3.2.0 or later versions, and set optimizationMode when creating the stream for screen-sharing. Choose the appropriate transmission optimization mode according to the shared content:
- If the shared content is mainly slides, texts, or static images, set optimizationMode as "details".
- If the shared content is mainly videos or games, set optimizationMode as "motion".

Set optimizationMode when creating the video track for screen sharing, and choose the appropriate transmission optimization mode according to the shared content:

As of v4.2.0, you can change the transmission optimization mode during a screen sharing session by calling setOptimizationMode.
