[Config Support]: Camera live view being cut off

[mabnz]

Describe the problem you are having

On 17.0-rc3, when I view a particular camera's record stream (higher quality - 3840x2160) the right side gets cut off, it's like the view is cropped.

The odd thing is that this only happens in Edge on Windows, not Edge on Mac. This doesn't happen on the low-res stream, nor does it happen when playing back recorded footage (at the full record stream resolution).

What could be going on here?

Based on the available sources, there's a known issue where live view displays can show cropping or incorrect dimensions in certain browsers(1). This appears to be related to how different browsers handle video stream rendering(1).

For your specific case with Edge on Windows showing a cropped right side on a 3840x2160 stream while Edge on Mac displays correctly, this suggests a browser-specific rendering issue rather than a Frigate configuration problem(1).

The documentation indicates that Frigate uses three different streaming technologies (jsmpeg, MSE, and WebRTC) and intelligently switches between them based on browser capabilities and network conditions(2). MSE requires certain audio codecs (PCMA/PCMU or AAC) and has varying support across browsers, with specific notes that iPhone requires iOS 17.1+ and Firefox is H.264 only(2).

To troubleshoot this issue, you could try:

1. Enabling "Compatibility mode" in the Live View settings for this camera, though the documentation notes this should only be used if you see color artifacts and a diagonal line(2)

2. Adjusting your camera's detect width and height to a standard aspect ratio (the documentation suggests converting non-standard ratios like 640x352 to 640x360)(2)

3. Forcing WebRTC mode by using the camera's two-way talk feature, which automatically switches to WebRTC(2)

Since this is browser-specific behavior on Windows Edge with a high-resolution stream, it may be related to how that particular browser handles MSE playback of 4K content.
