I imagine this could also be something in the kernel rather than in zbar-tools
but I haven't looked into that yet.


you can try:

mpv av://v4l2:/dev/video0

to test.


mpv manages to show video from the even-numbered devices but the fps is *very* low

Given that, did you find any other program that worked with the videodevices? Maybe it is a bug in the kernel driver after all.


Cheers Jochen
