Demo does not work with QT 5.4.1 and gcc64

[sk2212]

I try to compile QmlVlcDemo with sources from github but I get following compile errors within QtCreator:

What`s wrong here?

It lack c++11 support, but I don't understand why, c++11 enabled at https://github.com/RSATom/QmlVlcDemo/blob/master/QmlVlcDemo.pro#L22

[RSATom]

hm.. you have -std=c++0x not -std=c++11 in your command line. What distro do you use?

[sk2212]

Ahh sorry, my fault.

Has to explicitly set my g++ compiler to version 4.9:

QMAKE_CC = gcc-4.9 QMAKE_CXX = g++-4.9

Project is building now :-)!

[RSATom]

Glad to hear about your success :)

Please close this issue if you have no any more questions.

Maybe we can use this issue for further questions...Building works, but when I try to start the project the program crashs:

Maybe the problem is that "'--enable-qt4'" option parameter? It should be "'--enable-qt5'", shoudn`t it?

I am using Ubuntu 12.04 LTS with 64bit system and QT5.4.1.

Thanks for your quick help!

[sk2212]

Okay...fix this problem with:

sudo /usr/lib/vlc/vlc-cache-gen -f /usr/lib/vlc/plugins/

It seems that I have to renew the plugin cache of vlc.

Hopefully the last error to fix:

Debug/QmlVlcDemo: double free or corruption

Hm.. It seems some bug there.

[RSATom]

you could try update QmlVlc subrepo to the latest version, but don't sure it will not break build of QmlVlcDemo

[sk2212]

Okay, will give it a try tomorrow. The crash is not reproducible. Sometimes it works, sometimes not. At all it is nice to to see to get vlc working within a qml file!!! Great job!!

[RSATom]

Thanks, I'll try update QmlVlc myself soon

[sk2212]

Okay...before I take a look deeper into this I have another question. Is it possible to play uPnP content at all? VLC player supports it so I think also this plugin?

[RSATom]

If VLC supports it - it should be no problem with it in QmlVlc

[RSATom]

I've updated QmlVlc to the latest version. And found that you could fix your problem with c++11 by adding QMAKE_CXXFLAGS_CXX11 += -std=c++11 to QmlVlcDemo.pro file.

Thanks for help! I will close this issue.
