Question

我一直试图获取GL纹理并从中生成SurfaceTexture，并提供给Camera目标端，以便我可以在着色器程序中使用Texture进行渲染。

在Camera2 API之前，我可以看到下面的API。 https://developer.android.com/reference/android/hardware/Camera.html#setPreviewTexture(android.graphics.SurfaceTexture)

我一直在寻找Camera2 API的等效API。有人可以提供提示吗？或者任何替代方法，比如使用TextureView的setSurfaceTexture（SurfaceTexture openGLMappedSurfaceTexture）？

尝试这样的事情：

            SurfaceTexture texture = mTextureView.getSurfaceTexture();
            assert texture != null;

            // We configure the size of default buffer to be the size of camera preview we want.
            texture.setDefaultBufferSize(mPreviewSize.getWidth(), mPreviewSize.getHeight());

            // This is the output Surface we need to start preview.
            Surface surface = new Surface(texture);

            // We set up a CaptureRequest.Builder with the output Surface.
            mPreviewRequestBuilder
                    = mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW);
            mPreviewRequestBuilder.addTarget(surface);

setPreviewTexture（）API的等效Camera2 API是什么？
