Mirroring causes a change in resolution. sdk version 1.3.4

[疾風劍豪]

Original output video resolution:1280 * 720

When I set setMirrorMode (MIRROR.MODEON_FRONT-ONLY),

output video resolution changed to: 720 * 1280

I need two videos, one from the front camera(DEFAULT_FRONT_CAMERA) and one from the back camera (DEFAULT_BACK_CAMERA).

I hope the resolution of the two videos is consistent.

when i use setTargetResolution, log:

 java.lang.UnsupportedOperationException: setTargetResolution is not supported.

at androidx.camera.video.VideoCapture$Builder.setTargetResolution(VideoCapture.java:1603)

Please!

Hi

This is an intended behavior when mirror mode is enabled. The result video is still up-right.

Here are two possible workaround

1. Enable surface processing with VideoCapture.Builder.setSurfaceProcessingForceEnabled(). This will rotate the video from the back camera as well, but it's an internal CameraX API that is not guaranteed to maintain.
   

2. Use the Media3 Transformer API to rotate the saved video. Check out the demo application for guidance: https://developer.android.com/media/media3/transformer/demo-application

Thank you very much!

setSurfaceProcessingForceEnabled()  meets my requirements.
