🐛 Android: Camera preview aliased/distorted when using Format + Frame Processor simultaneously

[antek-p]

What's happening?

When combining a custom format (via useCameraFormat) with a Frame Processor, the camera preview becomes aliased/distorted and loses quality on android. I could reproduce it on two devices.

• If I remove the useCameraFormat and let the frame processor -> preview looks sharp and correct.
• If I remove the frame processor & let the useCameraFormat -> preview looks sharp and correct
• If I use both -> aliasing/distorted

I first noticed this issue in my own app (Expo SDK53, latest version of Vision Camera). To confirm it wasn't specific to my setup, I also built and ran the official example app — and was able to reproduce the exact same aliasing issue there too with the same devices.

See images below (both have a frame processor & format).

I think I've just encountered this too, and have worked around it thanks to a comment on another open issue: #3430 (comment)

All I added was a custom module with a dependency on v1.5.1 or higher for camerax to the dependencies section of its build.gradle

I've not done extensive testing on this - just that it looks like it fixes what I was seeing on my camera

    def camerax_version = "1.5.3"
    implementation "androidx.camera:camera-core:${camerax_version}"
    implementation "androidx.camera:camera-camera2:${camerax_version}"
    implementation "androidx.camera:camera-lifecycle:${camerax_version}"
    implementation "androidx.camera:camera-video:${camerax_version}"
    implementation "androidx.camera:camera-view:${camerax_version}"
    implementation "androidx.camera:camera-extensions:${camerax_version}"
