Description

vbi device detection code in videosource.cpp scans /dev/v4l and /v4l.

It should scan /dev/v4l and /dev instead.

Patch to scan /dev instead of /v4l

Note: Attached patch also adds a check to remove symlinked devices. I get:
/dev/vbi (symlinked to default device - /dev/vbi0) /dev/vbi0

Only the vbiX devices are required.

  • Status changed from new to closed
  • Resolution set to fixed

(In [10886]) Fixes #2214. Checks for VBI devices in "/dev/v4l" and "/dev" not "/dev/v4l" and "/v4l".

I didn't apply the other change in the patch. I would rather see duplicate detection based on major and minor device numbers, like we do with video devices. Checking for symlinks is too fragile.
