Hi,
I have two B0261 IMX291 175° fisheye USB cameras. The H.264 output at
1920×1080 appears to crop the sensor rather than scale the full sensor
area down to 1920×1080. This reduces the effective FOV.
V4L2 shows no ROI or sensor mode controls available.
If anyone else has found success in tweaking the auto cropping feature of the UVC module before it is encoded to H264, I would be greatful for your help.
Platform: Raspberry Pi 4, Raspberry Pi OS Trixie (Debian 13)
