Frame processor not working with v2.0.0?

[jpribble]

What are you trying to achieve or the steps to reproduce?

I'm trying to use the frameProcessor() feature to analyze preview frames from the camera.

How did you initialize FA?

Fotoapparat
        .with(this)
        .into(cameraView!!)
        .previewScaleType(ScaleType.CenterCrop)
        .photoResolution([custom_selector])
        .previewResolution([custom_selector])
        .lensPosition(single(LensPosition.Back))
        .focusMode(firstAvailable(
            continuousFocusPicture(),
            autoFocus(),
            fixed()))
        .flash(off())
        .frameProcessor {
          processFrame(it)
        }
        .previewFpsRange(highestFps())
        .cameraErrorCallback { e ->
          [error_handling_code]
        }
        .logger(logcat())
        .build()

What was the result you received?

The frame processor's invoke(frame) callback is never called. Is this feature still a work in progress for version 2.0.0 or should this be working? I noticed that the sample app's Kotlin activity doesn't use a frame processor but the Java activity does. I tried modifying the sample app to use the Java activity but its SampleFrameProcessor didn't receive any callbacks either.

What did you expect?

I expected the frame processor to receive callbacks with preview frames from the camera.

Context:

• FA version: 2.0.0
• Devices/APIs affected: Tested on Samsung Galaxy S8 running Android 7.0.

It should be working. I will take a look. Thanks for reporting!

FotoapparatBuilder had not linked a field. Fixed in 2.0.1 (already out)
