When creating a CameraEffect using PREVIEW or VIDEO_CAPTURE, the filter effects implemented in OpenGL are rotated.

[Hong Wang (LazyIonEs)]

When creating a CameraEffect using PREVIEW or VIDEO_CAPTURE, the filter effects implemented in OpenGL are rotated.When I change the targets to PREVIEW, it displays correctly again; currently, I am using surfaceOutput.updateTransformMatrix to correct the rotation, which works correctly in PREVIEW, but is rotated again when combined with VIDEO_CAPTURE. What should I do?

Hi,

If you are looking to apply post-processing effects to your output, you can find a sample implementation of tone mapping in the official CameraX test app repository. The sample demonstrate how to use the CameraEffect and SurfaceProcessor APIs for different use cases.

Here are the link to the sample implementations:

• ToneMappingSurfaceEffect.kt

To help us better understand the specific issue you are facing, could you please provide a code snippet of how you are currently implementing the effect or configuring your pipeline?

Thanks!
