How to make square crop in new video capture

[Hossein Kheirollahpour]

Hello Group

How we can make an video output center square in the new video lib(androidx.camera:camera-video:1.1.0-alpha12)?

In the previous VideoCapture(androidx.camera:camera-core:1.1.0-alpha08), we can set target resolution but in the new one cant be able to do this.

Since the new version gets quality, can we do the same config?

Using VideoCapture in new library(alpha12):

val qualitySelector = QualitySelector.from(Quality.SD)
val recorder = Recorder.Builder()
.setQualitySelector(qualitySelector)
.build()
val videoCapture = VideoCapture.withOutput(recorder)

Using VideoCapture in old library(alpha8):

val videoCapture = VideoCapture.Builder()
      setTargetResolution(Size(deviceWidth, deviceWidth))
      .setTargetName("VideoCapture")
      .build()

Hello,

This is Trevor from the CameraX team. Unfortunately the new video APIs don't yet support this. However, we are working on this feature. The legacy restricted VideoCapture class could not guarantee a square aspect ratio on all devices, though many devices may have supported it. We want to make sure this feature will work on all devices, so it will take a bit more time as we work through performance and compatibility issues. Please stay tuned.

Thanks a lot.

We are waiting for this attractive feature.

Best Regards.

Any update on this feature?

Hi,

CameraX Video support WYSIWYG feature since 1.3.0-alpha01 via ViewPort API.

Arbitrary aspect ratio can be set in the ViewPort.Builder()

ex:

ViewPort viewPort = new ViewPort.Builder(new Rational(1, 1), mViewFinder.getDisplay().getRotation())
        .setScaleType(ViewPort.FILL_CENTER)

        .build();
UseCaseGroup useCaseGroup = new UseCaseGroup.Builder()

        .setViewPort(viewPort)
        .addUseCase(preview)

        .addUseCase(videoCapture)

        .build();
mCamera = mCameraProvider.bindToLifecycle(this, mCameraSelector, useCaseGroup);
