I've found the way how to build application with Qt5 and libvlc on linux and don't get crash on start: sudo /usr/lib/vlc/vlc-cache-gen -f /usr/lib/vlc/plugins It will rebuild plugins cache and Qt4 gui plugin will not load on libvlc init. Thanks RSATom for your post. FYI I have already done with thi...

Thanks RSATom . Now I am able to play Qmlvlcdemo which is shared by you in QT 5.4, Ubuntu 14.04 as per suggestion. But my need is to run vlc-qt libs in QT 5, Ubuntu 14.04. It would be great for me if anyone suggest me to run vlc-qt libs in QT 5, Ubuntu 14.04. Anyway, I am very thankful to all Videol...

Checked right now on latest Linux Mint x64 + qt 5.4 + https://github.com/RSATom/QmlVlcDemo: With libqt4_plugin.so it's crushed on start, after rename it to libqt4_plugin.so_ - it runs ok. I downloaded the code from the above link but I get the empty folder QmlVlcDemo-master/deps/libvlc-sdk and mlVl...

move libqt4_plugin.so away from Vlc plugins folder should be enough.

at least for me it worked. Maybe you have some another problem too.

Can you please let me know on Ubuntu and QT version on which it worked at your end ? I am using QT 5.4 and Ubuntu 14.04, 64bit.

Are you sure that vlc-qt libs could not compile on QT5 in Ubuntu ? I never wrote or implied that. It is just a fact that all released versions (as of today) of Ubuntu provide (Lib)VLC compiled with Qt4, not with Qt5. That being said, the only reason why it crashes is a bug in Debian/Ubuntu packagin...

and again, problem is not with vlc-qt (or any other wrapper). Problem is Vlc uses Qt for gui on Linux. And this day it's usually Qt4. When you link your own application with Qt5 and libvlc, on start libvlc anyway loads all plugins (even if some of them will not be used), and GUI plugin is one of th...

Yes, I do. On Xubuntu 14, but not vlc-qt - my own wrapper. But it doesn't matter, since problem is in compatibility between qt4 and qt5. Thanks for your answer. Can you please let me know which wrapper you have used in QT5 in Xubunutu 14 instead of vlc-qt libs ? One more thing, now is it sure that ...

You could link your libvlc application with qt5, but you have to remove libqt4_plugin.so to be able to run it.

Thanks for your reply. Do you able to link vlc-qt libs with QT5 in Ubuntu at your end ?

You can´t have two versions of Qt in the same process. Since Ubuntu currently compiles VLC with Qt4, you need to do likewise. Thanks for your post. Are you sure that vlc-qt libs could not compile on QT5 in Ubuntu ? Because somewhere in my research I read that vlc libraries version 2.2 or onwards ca...

At my end vlc-qt libraries working in Qt 4.8.6 but not working in Qt 5 in Ubuntu 14.04.
In Qt5 vlc-qt libraries compiled successfully but getting crashed while run the project into Qt5 in Ubuntu 14.04. Can anyone help me in this ?

Thanks.
