tmsd2001 commented 5 years ago

I have a PureThermal 2 with Lepton 3.5. Windows 10 VLC play the video stream, on Ubuntu 18.04 VLC can't play, the log show "v4l2 stream error: cannot open device '/dev/video0': Operation not permitted" and "audit: type=1400 audit(1553403072.607:47): apparmor="DENIED" operation="ptrace" profile="snap.v lc.vlc" pid=2176 comm="vlc" requested_mask="trace" denied_mask="trace" peer="unconfined"". Permision of /dev/video0 und /dev/bus/usb... is set to my username.

General v4l2 support is not in the scope of the GetThermal project, which doesn't even use v4l2.

OK, you say v4l2 is not in the scope, but this is the Video device PureThermal 2 install in Ubuntu. Or how can I stream the PureThermal 2 board in Ubuntu?

You can find some examples for capturing data somewhere else: https://github.com/groupgets/purethermal1-uvc-capture

Or you can consult the Flir Lepton google group: https://groups.google.com/forum/#!forum/flir-lepton
