CAM500 and /dev/video0
Posted: Sun Nov 13, 2016 7:12 pm
Doing development for ml/vision tasks on neo air. But, struggling with access to CAM500 as dev/video0 from opencv/aruco utilities.
Using Ubuntu (sorry, I know this is Debian forum, but there is no Ubuntu forum).
Successfully built opencv and most of aruco.
mjpeg-streamer works, and ffmpeg creates mp4 file that I can view properly on host machine.
Have no problems with x forwarding on ssh (ssh -X root@xxx.xxx.xxx.xxx) - properly runs, opens windows, etc. BUT displayed video looks like this:
Image window is responsive to change in presented images - just looks like X or opencv does not have the right format. AND aruco tools cannot find AR markers in it - and they can on other platforms.
Seems likely I am missing something in opencv access to this device or cam config - but I have not figured it out, and am running out of things to try.
Any help appreciated.
