Screen Flashing/Blanking/Restart?

[mcmcomput]

Describe the bug
The PI boots up fine, starts loading cameras approx 5 sec apart then after about a minute the screen goes black like it lost connection, sometimes flickers once or twice over a period of a minute or two before the camera service restarts i think and re-opens the cameras one by one. I may just have something configured wrong, but it seemed pretty easy to figure out between the two configs. Both are attached for reference.

• displaycameras Version: 0.8.3.3

**Display Configuration

• Display/Monitor resolution: 1920x1080
• Window matrix: 2x2 (3 cameras)
• Feed resolution: 640x360

Camera information (please complete the following information):

• Number of cameras: 3
• Camera models: Hikvision
• Unmanaged

Features enabled (please complete the following information):

• Rotation: no
• Display Blanking: yes (tried both)
• Display Detection: no

Your logs are interesting. I've never tried camera names that are numeric only, and omxplayer is objecting to a DBUS address specified in the omxplayer command switches. For each camera, the DBUS address is the default address (which should be totally fine) appended with ".camera_name". I suspect that numeric camera names must violate some basic namespace restrictions for the DBUS address. I suspect all is well until the first watchdog run where players won't return a play status via DBUS. Try camera names that aren't numeric, eliminate the extra feeds in the layout file, and retry. Please, report back: If numeric names are a problem, I'll need to include that warning in the documentation. Thanks, A

I changed them to "One Two Three" instead. :) Feeds are holding solid now for 30+ minutes.

Fixed with documentation of DBUS namespace restrictions in README.md with commit c61e4c1
