Re: is avplayer broken?

Hi Steven,

Yes I saw these warnings on the console during migration of QtAV code
in digiKam core.

This is relevant of avplayer implementation which is a puzzle at init.
I tried to fix it but it did not work.
There is a mess in code structure from the QtAV author in fact.
On the other hand, I don't remember seeing this error at digiKam
startup. Right ?
