Launch file logs webcam instead of Zed

Hi, the node for some reason opens up my webcam instead of the zed camera. The zed ros wrapper works fine though. Any idea as to why this is happening?

Here it's assuming the 0 camera is the zed, maybe change this to 1, see if that works

Yes, that worked. Thank you!

I also wanted to ask if you knew why it is difficult to use stereo_image_proc on the higher resolutions?

Also, why is it that the zed_ros_wrappers raw images dont create a pointcloud in stereo_image_proc?

point cloud requires depth image, Zed need GPU to calculate depth. Raw image only has RGB.
