Virtual cameras are not supported for video messages #3375

Hi,

I believe I found an issue with how Unigram handles cameras.

I use iVCam as a virtual camera on Windows. When I make a video call, Unigram correctly detects and uses the iVCam virtual camera without any problems.

However, when I try to record a video message, Unigram seems to ignore the virtual camera and attempts to use the laptop's built-in webcam instead.

I also tested this by completely disabling the laptop's built-in webcam in Windows. After doing so, video calls still work normally using iVCam, but when I try to record a video message, nothing happens — the video message recording simply doesn't start.

Interestingly, the official Telegram Desktop client does not have this issue. It correctly uses iVCam for recording video messages as well.

This makes me think that this could be a bug or a limitation specifically in the way Unigram handles cameras for video messages.

If needed, I'd be happy to provide logs, additional details, or perform further tests to help reproduce and diagnose the issue.

Thanks for your work on Unigram!
