Downloading Samples

[thescouse]

Hi everyone.
I just wanted to experiment with the Camera example here:
http://qt-project.org/doc/qt-5/qtmultimediawidgets-camera-example.html

and the Video widget example here:
http://qt-project.org/doc/qt-5/qtmultimediawidgets-videowidget-example.html

I can't find any place to download.
Are they downloadable? Or we just get the text of the programs?

Hi,

Did you have a look at your Qt installation directory? Normally they should be there.

How did you install Qt?

[thescouse]

I installed it through ubuntu store. It doesn't come with QtMultimedia.
Ok, now I had to download it through sudo apt-get install command for QtMobility..
I got the examples. But the executables don't do anything.
What now?

[Eddy]

What Qt version do you have?

[thescouse]

Qt 4.8

[Eddy]

What do you mean by: don't do anything, you should see something in the compiler / application ouput panes when you hit the run button from Qt Creator.

[thescouse]

I opened an executable..where all the downloaded examples were..and not within the IDE. It did nothing.

[thescouse]

They are not visible through Qt.

[Eddy]

did you try

@
./exampleProgram
@

from the console?

(exampleProgram should be replaced with the name of the example you want to run.)

[thescouse]

./camera: error while loading shared libraries: libQtMultimediaKit.so.1: wrong ELF class: ELFCLASS64

[Eddy]

are you able to run another example ? (not qtmultimedia)

If your goal is to experiment with the examples I advice to do that using Qt Creator. There you will have more feedback from the system, you can debug and so on.

[thescouse]

Yes the other examples are running this way. Is there any installation problem?
I installed them using sudo apt-get install qtmobility-examples..
And I am trying to do it in At side by side..just wanted to experiment with premade samples.

Hi,

If you are starting with Qt, I recommend using Qt 5. Qt 4.8 is rather old.

Also, Ubuntu modified the Qt 4.8 packages (which I think caused more trouble than it's worth). The Qt 4.8 packages in the Ubuntu repository are different from standard packages.

[Eddy]

JKSH is right.

I used to install the Qt package from Ubuntu to get the dependences right. Then i downloaded the installation packages from the Qt site, see download link on top of this page.

That way you can experiment with the latest toys. ;-)

Year..ubuntu's qtmobility is a little messed up..thanks for your help.. :)
I am thinking of incorporating opencv for the same now.
