Thank you for posting in the Developer Forum. Your post does not provide enough details. Could you share steps to reproduce, SDK versions, and screenshots of the error you are seeing? This will help diagnose what may be happening.
At this time, the user can go to the function interface, fill in the pairing code, and cast the screen.
The question I want to ask is: Does the screencast function user have to log in, i.e. step 3 above(Screencasting code screencasting, non-conference screencasting),
I also tried to remove step 3 and then perform screencasting, but the screencasting failed,
When the screencast code casts the screen, an error is returned SDKERR_UNINITIALIZE: 7
The zoom client user can also cast the screen without logging in
Another question is, does the pairing code cast screen not support selecting the window to cast the screen on? There is no such setting item in the sdk, but in the zoom client
