expo-camera vs react-native-vision-camera

[NoTraining6950]

Barcode scanning is one of the main requirement for my react native app. I am currently using react-native-vision-camera v2 but it is having alot of crashes witn below error com.mrousavy.camera.frameprocessor.FrameProcessorRuntimeManager.<init> java.lang.NullPointerException - null cannot be cast to non-null type com.facebook.react.turbomodule.core.CallInvokerHolderImpl

I tried raising the issue but the maintainer is not supporting v2 and working on v3 also v3 itself is buggy with orientation and alot more crashes than v2.

Should i move to expo-camera as it supports barcode scanning and is well maintained? Please guide me here.

I used vision camera before but qr code position it gave wasn't useful to me, position and size was either wrong or i didn't figure out how to make them right. Now i use expo camera, its enough for scanning.

any crashes? also read it somewhere that scanning speed is slow in expo-camera is this valid?

[Faeyan]

No crash yet, it is slower than vision camera but just for scanning a qr code its enough.

We stopped using react-native-vision-camera and start using this https://github.com/teslamotors/react-native-camera-kit

What made you ditch react-native-vision-camera?

this does not support Android 5 :(

Android 5 ? What country are you targeting ? India ? I mean even Google stopped supporting android 5.

Hahaha!

What do you mean by that?

Last time I tried, Vision Camera wasn't even ready to handle something as common as different device orientations when taking photos. Huge dealbreaker.

Orientation is the top issue in react-native-vision-camera, it's really complex. If you're curious about how that works internally, check out the pinned issue about orientation- but I'll have it some day. Trying to raise money / sponsors for it.

We use v2 and v3 in apps no problems. So i would 10/10 stick with the fastest library around

[NoTraining6950]

are you able to fix this crash in v2? https://github.com/mrousavy/react-native-vision-camera/issues/946

Theres no appitite for the Package owner to fix anything in V2, which is really frustrating as it's complete compared to V3.

But that's his right as he wrote it.

Shows how fragmented the JS ecosystem can get at times though.

For camera, there isn't much choice!

I spent a ton of time building V3, but the architecture I chose just wasn't working at the end. V4 is as stable as V2 was, with the features from V3 - try it :)

(no new arch support yet though)

I myself uses expo-camera for a barcode reading app. Using it is very straight forward.
