setPreviewTexture() API 的等效 Camera2 API 是什么? [英] What is the equivalent Camera2 API for setPreviewTexture() API?

问题描述

我一直在尝试获取GL Texture并从中生成SurfaceTexture，并将其提供给Camera目标端，以便我可以在着色器程序中使用Texture进行渲染.

I have been trying to get the GL Texture and generate a SurfaceTexture from it, and provide to the Camera destination end, so that i can use Texture in the shader program to render.

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)

Before Camera2 API, i could see the API below. 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?或者任何替代方案，例如使用 TextureView 的 setSurfaceTexture(SurfaceTexture openGLMappedSurfaceTexture) ?

I have been hunting the equivalent API for Camera2 API. Could someone provide the hint? Or any alternative say something like, using setSurfaceTexture(SurfaceTexture openGLMappedSurfaceTexture) of TextureView?

推荐答案

试试这个:

            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);
