#1170 Multicam Option No Longer Available

[Lukas Robert Hron]

Hi Open Camera Team,

I’m experiencing an issue with the multicam option in the Open Camera app on my Nothing phone 2. It used to work flawlessly, but it has disappeared from the app’s settings and functionality. The last time I can confirm it working was on April 15th.

I’ve tried using other camera applications to access the wide-angle lens on my device. However, the only app that has successfully detected and used this lens is GCam.

Is there a known issue or recent update that might have affected the multicam functionality in Open Camera? Any advice on how I might restore this feature would be greatly appreciated.

I’ve included the debug info below, and I’m attaching an image showing GCam detecting the wide-angle camera for your reference.

it only identifies two cameras. they are for cameras on my phone three on the back and one on the front

"I’ve tried using other camera applications to access the wide-angle lens on my device. However, the only app that has successfully detected and used this lens is GCam."

This means the device isn't making the cameras available to third party applications. There are backdoor methods one can use - GCam tends to be ported specifically for each device, so it's easier for them to use such methods. Please see https://opencamera.org.uk/help.html#faq "Why doesn't Open Camera support dual / multiple cameras?" etc.

I don't know why it changed, but that suggests likely a change in some phone update. I don't know if they have any forums to request this back.

I know that

This is a hack - on other devices, this will lead to buggy behaviour where cameras are exposed that hang or otherwise don't work. The problem here is that the device does not support exposing the cameras to third party camera applications via the Android camera API.

But I think users should have the right to control their own devices, it shouldn't be limit by these device productor.
if users can input additional cameraids and open the camera, we could have the freedom to choose any camera. Even if an error occurs, it is entirely the user's own choice.
I am trying to complete the code.

[Anonymous]

I agree

Especially since it seems like phone manifacturers are purpously hiding their cameras from the api to discurage people from using external apps like opencamera.
I suspect this is what happened in this case since it stopped working after april 15th with no changes to opencamera

[tumuyan]

I have open a merge request, the link is the apk build by myself (for test)

This absolutley solves the problem with the wide angle but it does tend to cause crashes whenever i'm navigating the menus. Been trying to load up a ghost image for a while and it always crashes when i try to do so
Do you think it'd be possible to look into it?
I'd be forever thankful !!
