Choose Rear Camera Device In OAP Manually - andykng - 03-30-2020

My Pi 4 setup combines OAP with a dash cam,  the dashcam is configured into the OAP build and uses the PICAM for front dashcam and a USB 

camera for rear dashcam.

I would also like to use a 3rd USB camera as a reverse camera with the aid of the rear camera feature in OAP.

The trouble is OAP fails to boot up, system freezes during or after the splash screen when 1 o 2 USB cameras are plugged in.

OAP and the DASHCAM (front & rear) work in independent builds, but the issue starts when I install the dashcam to the OAP build.

Theres seems to be a conflict between which device has access to a particular camera.

So my question is would it be possible to introduce the option to manually select the camera OAP selects either from a list or entering the device 

location manally, OAP automatically searching for a camera unfortunately is preventing my setup working as I would like it.

Many Thanks
Andy

I experienced similar issues when I had usb soundcard, usb mic and usb video capture card all plugged in together. It freezed twice, but mostly the problem was that raspbian randomly changed default usb sound card to another usb peripheral (sometimes uwb mic gets defaulted, and sometimes usb audio/video capture card for backup camera). And that messed up the system somehow. Most of the time I only have to exit OAP and change back default sound source.

Thanks

Your experience made me start looking further, now even when a usb gps was plug it failed to boot up.
so I rebuilt OAP 6.1 from scratch now the issue has gone away thanks for sharing your experience.
But still have problems with one of the camera's not being available to either OAP or the dashcam.

Tried all OAP rear cam settings with no joy.

Being able select or enter the camera would really help
