❓ Is reanimated v3 supported yet?

[jzxchiang1]

Question

I tried using reanimated v3 with react-native-vision-camera v2.11.2.

It generally works but frame processors in particular do not work on Android. (It works on iOS.)

Specifically, I am trying to use vision-camera-code-scanner v0.2.0, which relies on frame processors.

The device logs I'm seeing in Flipper are:

Setting new Frame Processor...
Found CameraView!
Adapting Shareable value from function (conversion to worklet)...
Successfully created worklet!
Called Frame Processor callback, but `frameProcessor` is null!
Called Frame Processor callback, but `frameProcessor` is null!
Called Frame Processor callback, but `frameProcessor` is null!
...
Removing Frame Processor...
Frame Processor removed!

Nothing crashes, but the frameProcessor is null warnings get logged very often (equal to my frameProcessorFps value of 5). Did reanimated v3 at HEAD break the frame processor code in this library? Thanks!

What I tried

No response

VisionCamera Version

2.11.2

Hey! That's interesting, I didn't try REA 3 yet. Let me know if you find anything that might be the cause of this issue!

Are there any logs or specifically areas of the codebase I should be looking at? I'm not too familiar with how to debug why frameProcessor is null. Thanks!

Vision camera fails to be build on rn 69. few issues. react-native directory used to have only react-native aar, but now it has hermes aar too. This leads finding rnAAR to fail.

If that is fixed the next error comes due to REA no longer containing pre-built aar, this leads extractJNI to fail

Can you share the folder structure on RN <0.68 and RN 0.69 for comparison?

[heroic]

This is 69

This is 68

similarly, REA doesn't have AAR anymore with 3.0.0

[mrousavy]

And what's inside of hermes-engine and react-native?

I'll have to update VisionCamera to Fabric/TurboModule to be compatible with the new system - not sure when I have some free time to do that

I was able to get the react native and android AAR paths to work. Couldn't get REA to work. Couldn't find the jni headers you were requiring earlier anymore in REA 3.

Hey - yep REA 3 is supported now! Both in V3 and V2 of VisionCamera
