🐛 frame-processor/unavailable: Frame Processors are not enabled

[jack828]

What were you trying to do?

Using this + the QR scanner library for QR detection.

Reproduceable Code

import { observer } from 'mobx-react-lite'

import * as React from 'react'
import 'react-native-reanimated'
import { StyleSheet, View } from 'react-native'
import { useCameraDevices, Camera } from 'react-native-vision-camera'
import { useScanBarcodes, BarcodeFormat } from 'vision-camera-qrcode-scanner'
import { Center, Flex, Heading, Text } from 'native-base'
import { useIsFocused } from '@react-navigation/core'
import Layout from '../../components/layouts/Layout'

export const ScanScreen: React.FC = observer(({ navigation }) => {
  const [hasPermission, setHasPermission] = React.useState(false)
  const devices = useCameraDevices()
  const device = devices.back
  const isFocused = useIsFocused()
  const [frameProcessor, qrCodes] = useScanBarcodes([BarcodeFormat.ALL_FORMATS])
  const [isActive, setIsActive] = React.useState(isFocused)

  React.useEffect(() => {
    ; (async () => {
      const status = await Camera.requestCameraPermission()
      setHasPermission(status === 'authorized')
    })()
  }, [])

  React.useEffect(() => {
    if (qrCodes.length) {
      console.log(qrCodes[0])
      navigation.navigate('details', { id: qrCodes[0].displayValue })
    }
  }, [qrCodes.length])

  return (
    <Layout noScroll noPadding>
      <View style={styles.overlayContent}>
        <Center pb={16}>
          {qrCodes.map((qrCode, idx) => (
            <Text key={idx} style={styles.qrCodeTextURL}>
              {qrCode.displayValue}
            </Text>
          ))}
        </Center>
      </View>
      {device != null && hasPermission && (
        <Camera
          style={StyleSheet.absoluteFill}
          device={device}
          isActive={isFocused}
          frameProcessor={isFocused ? frameProcessor : undefined}
          frameProcessorFps={1}
        />
      )}
    </Layout>
  )
})

What happened instead?

frame-processor/unavailable: Frame Processors are not enabled.

The app works perfectly after a completely clean start - and after code changes (or bundle refresh) I can't use the frameProcessors function at all.

I'm just guessing here - I disabled the assertFrameProcessorsEnabled call in node_modules/react-native-vision-camera/src/Camera.tsx and I get the error:

Invariant Violation: Tried to register two views with the same name CameraView, js engine: hermes

So, I can only guess (a proper guess) that this library perhaps is not tearing down views correctly, so next run they are not initialised correctly?

I've managed to find a temporary fix (it stopped working after a while) by making the following change:

-     {device != null && hasPermission && (
+     {device != null && hasPermission && isFocused && (

Relevant log output

Interesting, does this work on iOS?

[jack828]

My colleagues on iOS tell me they haven't experienced the issue, but ill update this thread if they do today.

[Mohamed-kassim]

@mrousavy this also happens with me after navigating to the screen app crashes with this error, after restarting the app it works fine

this is the error `com.facebook.react.common.c: frame-processor/unavailable: Frame Processors are not enabled.

Are you sure that you're not using some remote debugger such as Chrome? It makes me wonder that the JSI functions are missing. Or maybe you are using fast-refresh and that breaks?

Can you reproduce the error if you simply open the app on your phone, without any debugger attached, and navigate through screens without fast-refresh or hot-reload?

[jack828]

Not using Chrome debugger - doesn't work with [insert package that I forget now] so I've been using flipper when required, but this occurs if flipper is connected or not.

Disabling fast refresh did not fix the issue if it already occurs. Tried this too:

• From a fresh app (react-native run-android) on device
• Disabling fast refresh (no option for hot-reload)
• Clean bundle yarn install && yarn start --reset-cache
• Navigate to page with camera, allow permission
• Works fine
• Navigate away from page
• Error Exception in HostFunction: com.mrousavy.camera.ViewNotFoundError: [system/view-not-found] The given view (ID 2559) was not found in the view manager.
• Reload app via metro bundler
• Navigate back to camera screen -> frame processors are not enabled

Hope this helps somewhat!

[mrousavy]

Ah, this is a race condition in the C++ view finder part. (findViewById, called on JS Thread through JNI, so C++ -> JS -> C++)

I have tried several times to fix this issue, but all of those times turned into long nights of debugging and after the morning light started to shine through my window I didn't want to spend more time on it. If you are interested in posting a bug bounty on the issue, let me know and me and my guys in my agency can look at this issue in greater detail to fix it once and for all.

[jack828]

No worries. If you don't mind linking any relevant code, I will see if I can't obtain time myself to see what I can do.

Appreciate it all the same!

[Kprashanth20]

Facing the same issue, by when this PR will be merged?

[mrousavy]

Please see if #691 fixes the issue for you guys 🙏

[jack828]

@mrousavy almost!

I no longer experience the original issue on reload, however navigating away from the screen that uses frame processors gives me

com.mrousavy.camera.ViewNotfoundError: [system/view-not-found] The given view (ID 12429) was not found in the view manager

I tried nuking node_modules & gradlew clean and no change.

[mrousavy]

Hm, okay that's a separate concurrency issue. will take a look soon

[vikasacharya16]

@mrousavy im using ubuntu, just installing the package and did changes in android manifest and other files given in docs.

VisionCamera: Frame Processors are disabled because REA v2 does not exist. C++ part will not be built.

for Android It won't work at all. To reproduce the issue just create one app and install the package. that's all, one will get this error.

[mrousavy]

that's all, one will get this error.

@vikasacharya16 the output you shared is not an error.

Please read up on what errors are and how to identify them, this is a simple log output. The actual error is further up.

[mrousavy]

@jack828 Hey! Does v2.13.1 fix the issue for you?

[jack828]

hey @mrousavy sorry for the delay. I've just upgraded the package in our project and it looks like the issue is completely resolved. I can interact with the camera as required with no issues.

Thanks so much!!

[jeffBoom]

I re-built and re-ran the app while also restarting metro with --reset-cache and that seemed to fix my issue. I also ran npm update but it didn't appear to update much in package.json, just some deps of deps.

After upgrade to "react-native": "0.70.6", the problem is still happening...

I can't get away from this "frame-processor/unavailable: Frame Processors are not enabled" error.

While building, it seems to log that "frame processors are enabled!"

So I'm not sure why it is throwing this error. I cannot use the "frameProcessor" prop on Camera.

[emaxedon]

Finally, I resolved this by upgrading my emulator SDK version to 31.

Hey, @Ankushpandey-ti - you need to ensure that your device is running Google Android API 31 or greater (Android 12 or greater).

[Ankushpandey-ti]

Hey , @emaxedon , i tried the development build of my app on android 13, still getting same error. It starts camera for a second and then crashes with same error as before And it works on my android emulator which uses a dummy camera. Error :- rame-processor/unavailable: Frame Processors are not enabled. See https://mrousavy.github.io/react-native-vision-camera/docs/guides/troubleshooting

Anyidea why is it so?

[emaxedon]

@Ankushpandey-ti In this case, it is unlikely that it is tied to the android SDK version. I see in your error logs that "Frame processors are not enabled". This will definitely cause issues.

I also notice you are not directly importing the entire "react-native-reanimated" module...

import {useFrameCallback} from 'react-native-reanimated';

should be

import 'react-native-reanimated';
import {useFrameCallback} from 'react-native-reanimated';

[Ankushpandey-ti]

Hey ,@emaxedon
I did a rebuild for android with no changes now the error is gone but the development app keeps crashing on starting the camera without any log or error. It some times gives a pop up -> "APP keeps stopping." One more thing that i noticed is if i keep the isActive = {false} , then the app doesn't closes. It closes after i turn the isActive ={true}

Also its working fine on emulator as it was earlier.

[DeepikaSharma5]

Any solution for this? @mrousavy

[Ankushpandey-ti]

Any solution for this? @mrousavy

@DeepikaSharma5 The solution that worked for me was.

1. I updated my android device to Andorid 13 as suggested by @emaxedon in above comments.
2. Insted of directly using true false for the isActive tag . I used isFocused.

Here is the sample code for better understanding

Not working code :- <Container> {isFocused && <Camera ref={cameraRef} photo={true} isActive={true} device={device} style={StyleSheet.absoluteFill} video={true} audio={true} enableZoomGesture={true} />} </Container>

Working Code part :- ` const isFocused = useIsFocused();

{isFocused && }

  `

[allangsilva]

In my case what solved this was add the Processor plugin class package to the MainApplication.java file in getPackages method.

Like:

@Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
         ...
         new VisionCameraFaceDetectorPluginPackage() // -> Frame processor 
      );
    }

[Bamorem]

I got the same issue but on IOS. And i follow all the steps on https://mrousavy.com/react-native-vision-camera/docs/guides/troubleshooting/

do someone has some some idea ?

in my Podfile i have platform :ios, '13' and ... if pod.name.eql?('vision-camera-code-scanner') || pod.name.eql?('VisionCamera') def pod.build_type; Pod::BuildType.static_library end end

[hassanharoon321]

Just close debugger mode on android

[mguerrero-exe]

¿Estás seguro de que no estás usando algún depurador remoto como Chrome? Me pregunto si faltan las funciones JSI. ¿O tal vez estás usando una actualización rápida y eso se rompe?

¿Puede reproducir el error si simplemente abre la aplicación en su teléfono, sin ningún depurador adjunto, y navega por las pantallas sin una actualización rápida o una recarga en caliente?

I stopped debugging by chrome and instantly the error went away so it worked for me

I have finally solve this issue. For today the latest version of react-native-reanimated is "3.0.2", this is not compatible with latest version of react-native-camera. Using version "react-native-reanimated": "^2.10.0" solved the issue for me after deleting yarn.lock file and then yarn install again.

Using version "react-native-reanimated": "^2.10.0" solved the issue for me after deleting yarn.lock file and then yarn install again.

Solved the issue for me too! I installed the 2.14.4 version. The site says: "If you want to use Frame Processors, you need to install react-native-reanimated 2.2.0 or higher." 3.0.2 is higher than 2.2.0 but not works, maybe you can fix this info on the site?

[nguyenduy2392]

Tôi cuối cùng đã giải quyết vấn đề này. Hiện tại, phiên bản mới nhất của react-native-reanimated là "3.0.2", phiên bản này không tương thích với phiên bản mới nhất của react-native-camera. Việc sử dụng phiên bản "react-native-reanimated": "^2.10.0"đã giải quyết vấn đề cho tôi sau khi xóa tệp yarn.lock rồi yarn installxóa lại.

my version is ^2.9.0. when update to 2.10.0 it work fine

thank you, its work for me

[opeyemijj]

If anyone is still facing this issue after changing "react-native-reanimated" version to 2.10.0, it is most likely because you are using a package like Firebase that requires use_frameworks! :linkage => :static. You need specify the build types for RNReanimated and Vision camera. Add the block below to your pod file and it should work.

pre_install do |installer| installer.pod_targets.each do |pod| if pod.name.eql?('RNReanimated') || pod.name.eql?('VisionCamera') def pod.build_type Pod::BuildType.static_library end end end end

[ghost]

It worked for me, and I didn't need to update reanimated, just add this line in the Podfile

Hi. I had this issue when running my app on Android device:

 LOG  Running "viewfinder" with {"rootTag":11}
 ERROR  system/frame-processors-unavailable: Frame Processors are not enabled!, js engine: hermes

I've installed react-native-worklets-core as it is suggested in the docs (https://www.react-native-vision-camera.com/docs/guides/frame-processors), and I was no longer getting the error mentioned above.

However, my app started to crash / close when launching the camera.

There was no error output, just this:

 LOG  Running "viewfinder" with {"rootTag":11}
 LOG  Loading react-native-worklets-core...
 LOG  Worklets loaded successfully

Module versions:

    "react-native": "0.72.4",
    "react-native-vision-camera": "^3.0.0",
    "react-native-worklets-core": "^0.2.0"

I've deleted node_modules and package-lock.json and did a clean re-install of the modules.

After that the app could no longer be launched or built, I was getting the following output:

FAILURE: Build failed with an exception.

I uninstalled react-native-worklets-core, removed react-native-worklets-core from babel.config.js, removed worklet notation from useFrameProcessor() handler and tried to launch the app, but I am back from where I started - I get system/frame-processors-unavailable: Frame Processors are not enabled!, js engine: hermes error.

I am not using Reanimated.

App and camera works fine if I am not using frameProcessor property on <Camera />.

I am testing this on a device with Android 10, I'll try to test on other Android versions.

[w4t3r-45]

any solutions so far , am still facing this issue in both IOS and Android

[nkloi]

The same with w4t3r-45

"react-native": "0.72.5",
"react-native-vision-camera": "3.0.0",
"react-native-reanimated": "3.0.0",

[w4t3r-45]

guys the solution was , installing reanimated package and also :

• remove node_modules
• remove yarn.lock
• remove podlock file
• install packages
• open android studio and click on the sync button to synchronize the files
• now should work

[peterdee]

@w4t3r-45 Hi. Could you please provide your package.json file and Android version that you use for testing?

[w4t3r-45]

@w4t3r-45 Hi. Could you please provide your package.json file and Android version that you use for testing? this are the versions of packages am using , besides that i tested on Android 10 physical device and on IOS 16.6 also physical device.

"react-native": "0.71.13", "react-native-reanimated": "^3.5.4", "react-native-vision-camera": "^2.16.1",

[peterdee]

@w4t3r-45 Thank you, I will try your solution.

[w4t3r-45]
