Camera support for React Native

🚧 🚧 🚧

react-native-camera is deprecated.

Due to the lack of maintainers and increased code complexity, react-native-camera is now deprecated in favor of react-native-vision-camera.

VisionCamera offers new APIs, better performance, improved stability and more features. It is actively maintained by @mrousavy and used in many production apps.

You can support the development of VisionCamera by sponsoring @mrousavy on GitHub.

You can find the old code of react-native-camera here.

See this issue for more details.

react-native-camera-v4's Issues

CameraX

CameraX is the recommended by Google and is the best documented Camera API.

It has the same API level support as the Camera2 API so Camera1 should still be around. Some features may be lacking and we would have to cover them with the Camera2 API, some research is needed in this regard.

Right now Camera 1 is the default and Camera2 is opt-in. We will move to CameraX as the default, Camera2 as the fallback for some features (might not even be necessary, research needed) and Camera1 as the legacy version.

barCodeTypes not working on iOs

In v3 the barCodeTypes are not correctly typed, it is not supporting the detected types on iOs.

For example, if I would like to restrict the valid codes to only QR, the TS typings say to pass:

barCodeTypes: ['qr']

but it does not work on iOs, I need to pass:

barCodeTypes: ['org.iso.QRCode']

I do not know if makes sense to fix this on v3 or just see this looking forward.

Add use cases to example apps

All use cases should be covered by the example apps to aid in testing.

Research end-to-end testing and CD

The example apps can be used for end to end testing and with the help of a provider we can automate the process. Detox comes up as the go-to framework for e2e testing.

Some possible providers are: CircleCI, GitHub Actions, AWS Device Farm, Bitrise

E2E testing the camera will be a serious challenge.

Migrate to ML Kit

Related to react-native-camera/react-native-camera#2018 and react-native-camera/react-native-camera#2931

Starting from version 4 we should deprecate all google cloud vision features and replace them with ML kit on both Android and iOS

In regards to react-native-camera/react-native-camera#2931 (comment) , @mikehardy do you have any ETA or roadmap for a standalone ML kit react native module we can depend on?

PRs created/merged after branching from v3

The core was ported from v3 at 1/17/2021.
I'm creating this issue to keep track of PRs to maybe incorporate them.

• Android - method to check if a video is corrupted
• writeExif dependency update
• writeExif data flood in some devices
• iOS - Orientation sensor
• iOS - Prevent RCT_CUSTOM_VIEW_PROPERTY usage
• Android- Set video resolutions

Accessing live preview pixels (without preview)

I have posted on the main react-native-camera repo but this seems newer:

Is there any way to get the image data (i.e. pixel array) from the current live preview? I don't need to show the preview, just get the pixels.

If there was a community chat (the one on expo seems not open anymore), I wouldn't mind to help develop this feature (on the native side) so that people can access the raw frames for their own use (e.g. AR projects).

add readme

it would be cool to have a readme to tell what this project is all about

it also good to have a list of issues that needs to be tackled

Swift Rewrite

Rewrite the native code for core and barcode in Swift.
Exclude any unused code (face detection, etc.), clean up the surface API for ease of usage and review portability with the Android API.

Swiftify can help a lot
