What's happening?

Moto G 5G 2022 is reporting only one physical device on the back camera, but there are three present.

Reproduceable Code

import { Camera } from 'react-native-vision-camera'
let devices = Camera.getAvailableCameraDevices()
console.log(devices)

Can you reproduce this issue in the VisionCamera Example app?

I didn't try (⚠️ your issue might get ignored & closed if you don't try this)

CameraX lists the "Moto G(22)" as tested and supported.

It's just phone vendors not respecting Android spec, should not affect your app though since you'll be using whatever the phone gives you. I have seen this multiple times, on multiple brands and models.

jkaufman commented 3 weeks ago

I've also seen it, but forget if I can expect different results from CameraX snd Camera2. I vastly prefer a multicam for my use case.

zzz08900 commented 3 weeks ago

I vastly prefer a multicam for my use case.

That could very much be a multicam, just the phone vendor being a jerk and reports wrong info. I've seen this a lot of times, cough, Huawei phones, cough.

Or Huawei somehow made a single camera that is capable of depth capturing, 5x optical zooming and taking ultra wide angle pictures.

jkaufman commented 3 weeks ago

Understood, thanks, so I shouldn't expect any camera API to report these devices accurately.

From what you described, it sounds like I should just ignore the physical device count and multicam-ness and go by capabilities?

zzz08900 commented 3 weeks ago

Usually we go by capabilities and pixel count, in most cases select the most powerful device/the device with highest resolution makes the phone throw in all the cams it has. If you don't have very uncommon use cases then this should work.

Do note that the most powerful device sometimes has a very long minimum focus distance, which could break in some scenarios like barcode scanning.

But sometimes even the capabilities aren't trustworthy, cough, Samsung phones, cough. In those cases we had to make phone specific patches.

zzz08900 commented 3 weeks ago

We even had Huawei phones reporting a duo cam with two ultra-wide-angle-camera and RNVC thought something's wrong and refused to boot up the cams.

I mean, sanity wise, I think what Huawei meant to say was one ultra wide angle + one depth capture or telephoto and somehow it get screwed up in the process.

jkaufman commented 3 weeks ago

Thanks, this is all very helpful. I have a pretty funky use case that benefits from a wide lens and lower-than-maximum capture resolution, but broad compatibility is most important.

mrousavy commented 2 weeks ago

Yea, I use the default Camera API - if it is not listed there, then its the vendor's fault.

Download the Camera2 API Probe app from the PlayStore to see if that can detect it.

As expected, it reports a single rear-facing camera with Level 3 support. Interesting that there is no zoom.
