Video isn't showing on surface created in thread. [Quick 2.3,QtGstreamer-1.2.0]

[Spruyt, Randy]

The surface needs to be created in the main thread. I had a similar issue previously.

Hi,

I’m having problem on render video on surface created by thread.
I’m using Quick 2.3, QtGstreamer-1.2.0.

Please see code below:
-----------------------------------------------------	
	void Player::stop(){
	    wCond.wakeAll();
	    while( !isFinished() )
	        msleep(100);
	}
	
	void Player::play()
	{
	    qDebug("playing");    
	
	    if( isRunning() ){
	        this->stop();
	        delete _surface;
	    }
	
	#ifndef THREAD_SCOPE
	    _surface = new QGst::Quick::VideoSurface();
	    ctx->setContextProperty(QLatin1String("videoSurface1"), _surface);
	    videoSink = _surface->videoSink();
	#endif    
	
	    this->start();
	}
	
	void Player::run()
	{
	    qDebug() << "Running" << this->currentThreadId();
	
	    /* Create video pipeline */
	    QGst::PipelinePtr _pipeline;
	    _pipeline =
QGst::ElementFactory::make("playbin").dynamicCast<QGst::Pipeline>();
	
	#ifdef THREAD_SCOPE
	    QGst::Quick::VideoSurface* _surface = new QGst::Quick::VideoSurface();
	    ctx->setContextProperty(QLatin1String("videoSurface1"), _surface);
	    QGst::ElementPtr videoSink = _surface->videoSink();
	#endif
	
	    if (_pipeline) {
	        QString uri =
"rtsp://184.72.239.149/vod/mp4:BigBuckBunny_115k.mov";
	        videoSink->setProperty("async",false);
	        videoSink->setProperty("sync",false);
	        _pipeline->setProperty("uri", uri);
	        _pipeline->setProperty("video-sink",videoSink);
	        _pipeline->setProperty("force-aspect-ratio",false);
	        _pipeline->setState(QGst::StatePlaying);
	    } else {
	        qCritical() << "Failed to create the pipeline";
	    }
	
	    qDebug() << "Waiting..." << this->currentThreadId();
	
	    /* Create wait condition */
	    wCond.wait(&mutex);
	
	    _pipeline->setState(QGst::StateNull);    
	
	    qDebug() << "Finished: " << this->currentThreadId();
	}
-----------------------------------------------------

When I don't define the THREAD_SCOPE the player show video normally, because
surface is created without the thread scope. Otherwise
don’t show any error, but video doesn’t showed.

I don’t know if it happen because thread scope, but It’s possible to create
surface and show video in thread scope?

For full code see:

Thanks!

Best Regards,
Daniel Fussia
