I get the Surface through the method createInputSurface() of MediaCodec, and then associate it with CameraX in the following way:

Preview encodePreview = new Preview.Builder()
.setTargetResolution(new Size(1280, 720))
.build();
encodePreview.setSurfaceProvider(new Preview.SurfaceProvider() {
@Override
public void onSurfaceRequested(@NonNull SurfaceRequest request) {
request.provideSurface(mInputSurface, ContextCompat.getMainExecutor(TestActivity.this), new Consumer<SurfaceRequest.Result>() {
@Override
public void accept(SurfaceRequest.Result result) {
// result.getSurface().release();
}
});
}
});

But an exception is thrown when running

Fatal Exception: java.lang.IllegalStateException: glDrawArrays: GL error 0x505

Thanks for reporting the issue. Which version of CameraX are you using? Does the error happen on a specific device? 

It's the OpenGL post-processing in preview caused the 0x505 error. Is there a reason that you want to record the preview stream instead of using the VideoCapture UseCase? 

Also it would be great if you could provide a minimal reproducible code sample.

Thanks
