unable to install QTSamplePlayer

[ShuaiZhao]

The following give me errors: jack@jack-1204:~$ sudo apt-get install qtmultimedia5-dev qtbase5-dev libqt5widgets5 libqt5core5 libqt5gui5 libqt5multimedia5 libqt5multimediawidgets5 libqt5opengl5 libav-tools libavcodec-dev libavdevice-dev libavfilter-dev libavformat-dev libavutil-dev libpostproc-dev libswscale-dev Reading package lists...

There is no way I can continue with making this work.

Any suggestions. BTW, the libdash is built successfully on this Ubuntu12.04 box.

Thanks Shuai
