** Description changed:
- since several weeks i loose acces to /dev/video0.
- I have one webcam and one TV tuner.
+ The File:
+ -rw------- 1 root root 4096 2009-10-04 20:30 usb-0000:00:02.0-4:PC Camera
+ is created by root with owner-only permissions and as this file has to be
accessed from a user account the camera is not accessible.
+
+ This is fixed in the new upstream version in lucid.
+
+ The attached patch prefixes the shm segment name with the effective uid.
+ It falls back to malloc if shm segment creation fails.
