I wanted to try something using Qt5 multimedia(a mp3 file playback), the test app compiled worked on developing machines, the realease build was archived, un-archived on target machine(which had gstreamer installed) but it didn't played anything, copied the content from Qt/5.3/gcc_64/plugins/mediaservice to the directory which contained the exacutable file, still nothing.
Ultimately installed Qt Creator(with Qt5.3) on targeted machine, after which still nothing was played.

Both developing machines are using Ubuntu 14.04.1 LTS and Qt 5.3 installed, shouldn't it work?

Any tips?
