[Qt-interest] phonon, gstreamer and gapless video playback

[Lorenzo Marussi]

Thank you for your suggest

Now I use two mediaobjects in a QStackedWidget and I switch beetween
them when signal finished() is emitted.

But.. I have to play the media when aboutToFinish() signal is emetted to
have a gapless playback,
if  I do that when finished() is emitted, the gap is still there.

And this is a problem, 'cause now I lost some frame on the next video..

Some ideas to resolve this now?

Thank you
