Live view aspect ratio different than original camera stream

[rici44]

I setup Frigate v14 in privileged container on Raspberry Pi CM4 module and connected Tapo C120 camera as tapo source. Frigate automatically choose MSE/WebRTC streams which are provided by go2rtc v1.9.2.

If MSE stream is chosen then live view aspect ratio is different than original camera stream. Camera has stream aspect ratio 16:9 but go2rt v1.9.2 provide MSE stream in aspect ratio 4:3.

If WebRTC stream is chosen then live aspect ratio is the same as the original camera stream 16:9.

I tested standalone go2rtc v1.9.7 with the same config of the same camera and results are the same (MSE 4:3, WebRTC 16:9).

Is it possible to setup correct aspect ratio in MSE stream ?
Is go2rtc doing something with original stream when providing MSE stream?

The camera is probably wrongly sending this information about the ratio. It's a fairly common situation.
Unfortunately I don't have any cameras with these problems to fix.
You can try to use ffmpeg source.

Why MSE and WebRTC streams are both OK in 16:9 when using Firefox browser?

What would help to solve this exact camera?

Won't it get more resources from CM4?

• Different decoder implementations
• Probably FFmpeg
