[Qt-interest] [ALMOST SOLVED] player Memory growing.

[Marek Bronowicki]

Hi...

I upgraded the Ubuntu to 10.10 and QT to 4.7.0. In fact there also was a 
consumption, but a little bit slower. I found in packages 
phonon-backend-vlc, so I deinstalled a gstreamer backend and installed 
vlc backend just for tests....  and voila - after 10 hours of process 
work - memory usage from 64MB-90MB. The only thing I have to test is the 
QWebView, because I disabled it for these tests.
Also I have to study this valgrind, beacause as for now I don't really 
understand what is he talking to me, but it's a matter of time :)

Thank you for all your replies.

Best Regards,
Marek Bronowicki

I noticed, that even QLabel is growing a memory about 4-8KB per view, but a movie is a real disaster. It should play short movies in infinite loop, so I cannot reboot the process every time that it grows to heavy.
