这是因为 Media Projection 和 Image Reader 无法跨进程使用，而 Netflix/Youtube 通常在自己的进程中运行。为了在 Netflix/Youtube 上使用 Media Projection 和 Image Reader，您需要使用 Android TV 上的屏幕录制功能来捕获屏幕上的视频帧。以下是示例代码：

private MediaProjectionManager mProjectionManager;
private MediaProjection mMediaProjection;
private VirtualDisplay mVirtualDisplay;
private ImageReader mImageReader;

private void startProjection() {
    if (mProjectionManager == null) {
        mProjectionManager = (MediaProjectionManager) getSystemService(Context.MEDIA_PROJECTION_SERVICE);
    }
    Intent intent = mProjectionManager.createScreenCaptureIntent();
    startActivityForResult(intent, REQUEST_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
        mMediaProjection = mProjectionManager.getMediaProjection(resultCode, data);

        // Set up the ImageReader
        int width = getWindowManager().getDefaultDisplay().getWidth();
        int height = getWindowManager().getDefaultDisplay().getHeight();
        int dpi = getResources().getDisplayMetrics().densityDpi;
        mImageReader = ImageReader.newInstance(width, height, PixelFormat.RGBA_8888, 2);
        mVirtualDisplay = mMediaProjection.createVirtualDisplay("ScreenCapture",
                width, height, dpi,
                DisplayManager.VIRTUAL_DISPLAY_FLAG_AUTO_MIRROR,
                mImageReader.getSurface(), null, null);
        mImageReader.setOnImageAvailableListener(new ImageAvailableListener(), null);
    }
}

private class ImageAvailableListener implements ImageReader.OnImageAvailableListener {
    @Override
    public void onImageAvailable(ImageReader reader) {
        Image image = reader.acquireLatestImage();
        if (image != null) {
            // Do something with the image
            // ...
            image.close();
        }
    }
}

这里的 startProjection 方法将启动屏幕捕获意图，当用户允许捕获后，onActivityResult 方法将获得 MediaProjection 对象。接下来，我们使用 `
