Question

我正在尝试将相机的预览从本机Java插件转移到一个整体中。我在Unity中创建Texture2D，将openGl的名称划分为Java插件。在Java代码中，我创建SearTexture并使用此纹理启动相机。我希望在Unity侧面可以看到相机预览。

我只能看到黑色的污迹。

在logcat中也有几个错误：

在logcat中也有一条奇怪的消息

Java本机插件：

...
public int startCamera(int pointer){
    PermissionFragment.RequestPermissions();
    int texturePointer = createExternalTexture(pointer);
    mSurfaceTexture = new SurfaceTexture(texturePointer);
    mSurfaceTexture.setOnFrameAvailableListener(this);
    mSurfaceTexture.detachFromGLContext();

    startPreview();

    return texturePointer;
}
...
private void startPreview() {
    mCamera = Camera.open();
    if (mCamera == null) {
        throw new RuntimeException("Default camera not available");
    }

    try {
        mCamera.setPreviewTexture(mSurfaceTexture);
        mCamera.setDisplayOrientation(90);
        mCamera.startPreview();
    } catch (IOException ioe) {
        // Something bad happened
    }
}
...
private int createExternalTexture(int pointer) {
    int[] textureIdContainer = new int[1];

    int error;
    if (pointer == 0) {
        GLES20.glGenTextures(1, textureIdContainer, 0);
        error = GLES20.glGetError();
    } else {
        textureIdContainer[0] = pointer;
    }

    GLES20.glActiveTexture(GLES10.GL_TEXTURE0 + textureIdContainer[0]);//GLES11Ext.GL_TEXTURE_EXTERNAL_OES);
    error = GLES20.glGetError();
    GLES20.glBindTexture(GLES11Ext.GL_TEXTURE_EXTERNAL_OES, GLES10.GL_TEXTURE0 + textureIdContainer[0]);
    error = GLES20.glGetError();

    GLES20.glTexParameterf(GLES11Ext.GL_TEXTURE_EXTERNAL_OES,
            GLES20.GL_TEXTURE_MIN_FILTER, GLES20.GL_NEAREST);
    error = GLES20.glGetError();
    GLES20.glTexParameterf(GLES11Ext.GL_TEXTURE_EXTERNAL_OES,
            GLES20.GL_TEXTURE_MAG_FILTER, GLES20.GL_LINEAR);
    error = GLES20.glGetError();
    GLES20.glTexParameteri(GLES11Ext.GL_TEXTURE_EXTERNAL_OES,
            GLES20.GL_TEXTURE_WRAP_S, GLES20.GL_CLAMP_TO_EDGE);
    error = GLES20.glGetError();
    GLES20.glTexParameteri(GLES11Ext.GL_TEXTURE_EXTERNAL_OES,
            GLES20.GL_TEXTURE_WRAP_T, GLES20.GL_CLAMP_TO_EDGE);
    error = GLES20.glGetError();

    return textureIdContainer[0];
}

Unity脚本：

void Start ()
{
    nativeCamera = new NativeCamera();

    texture = new Texture2D(1024, 720, TextureFormat.ARGB32 ,false, false);

    p = nativeCamera.StartCamera((int) texture.GetNativeTexturePtr());
    rawImage.texture = texture;
}

如果您能指出我的错误，我将不胜感激。

对不起，我的英语。
