RTMP : QtAV to OpenCV

[pebdev]

Hi, I use latest version of QtAV.

My goal :

• receive RTMP stream with QtAV (done)
• display it in a Qt application (done)
• process it in parallel with openCV (not done)
• display opencv result (need to procress image before)

Current way that I use to get and display image with QtAV :

...
this->m_avPlayer = new QtAV::AVPlayer(this);
this->m_videoView = new QtAV::VideoOutput(this);

if (!this->m_videoView->widget())
{
    std::cout << "QtAV error : can not create video renderer" << std::endl;
    return;
}
this->m_avPlayer->setRenderer(this->m_videoView);
this->m_avPlayer->play(this->m_path)
...

I tried lot of things (VideoFrameExtractor,VideoFrameConverter on positionChanged) but I can't find solution to extract images from the AVPlayer or VideoOut. Is it possible ?

Thanks.
