[Interest] QML Video with Phonon

[Robert Voinea]

Hi list

I have tried to create a QML Item for video playback using phonon. For that I 
am creating a video widget and display it in a QDeclarativeItem via a 
QGraphicsProxyWidget.

This is the tutorial I have used for inspiration
http://www.meegoexperts.com/2011/09/phonon-video-player-qml/

Everything works OK if the video is local or if the network path to the video 
source is OK (eg: reachable and not too slow).

If the network path is NOT ok (eg: video source is not available or network is 
slow) then the GUI freezes until the video is available... or a timeout is 
reached. This is unacceptable for my project.

I have been using for testing a local file AND a network webcam via RTSP 
protocol. Phonon backend vlc.

In the phonon documenation it is said that:
"Note also that most of the functions in this class are asynchronous. For 
instance, a media source may not play immediately after you call the play() 
function."

Do you have some hints on how to make the GUI not to freeze if the media 
cannot be reached?... or while the media is loading?...

(As a backup I could be using QX11Embed and vlc... although I could not find 
the wid command line parameter for vlc...)

Thank you in advance! :)
