How to convert a CVImageBufferRef to an OpenGL texture
outputImageProviderFromTextureWithPixelFormat:pixelsWide:pixelsHigh:name:flipped:releaseCallback:releaseContext:colorSpace:shouldColorMatch
       
CVImageBufferRef imageBuffer = CVBufferRetain(mCurrentImageBuffer);
 
    GLuint                  texture = CVOpenGLTextureGetName(imageBuffer);
