Mapping with 2 webcams as a stereo webcam isn't working #1634
Description
I'm trying to use two webcams as a stereo cam. I built rtabmap in Arch linux. I made a virtual video device with a side-by-side stream of the two webcams. If I try to start Mapping, I get this error:
"[ERROR] (2026-01-01 21:01:28.501) CameraStereoVideo.cpp:232::init() Calibration resolution (640x480) cannot be set to camera driver, actual resolution is 640x480. You would have to re-calibrate with one supported format by your camera. Do "v4l2-ctl --list-formats-ext" to list all supported formats by your camera. For side-by-side format, you should set listed width/2."
But mapping starts anyways, I think one camera isn't working. The odometry is looking something like this( the half-way transparent picture doesn't move). Calibrating the camera works and the odometry does work in the "Test" modus. If i cover one camera, the points disapear.
