For ios, the functionality in this pr is already working?

thomas-coldwell commented 2 years ago

Yes you can use it already for iOS with the useSyncFrameProcessor hook, but please be aware this might change. Revisiting the PR shortly as I got busy with work, but will be working on Android support next week. Cheers!

I convert the frame to Bitmap/UIImage and then convert it to base64: https://github.com/tony-xlh/vision-camera-dynamsoft-label-recognizer/blob/328624d0d1daf3583886d2958a938ac90963bfdc/ios/VisionCameraDLRPlugin.swift#L88. Don't know if there are better options.

Going to also mark this as a duplicate of https://github.com/mrousavy/react-native-vision-camera/issues/724. We are actively working on adding support for write-back frame processors in Vision Camera V3 (the in-progress PR for this functionality can be found at https://github.com/mrousavy/react-native-vision-camera/pull/1198).
