[Solved] QML Video on the desktop
-
4.7.1 has quite a few fixes if you see the change log
-
Yay!! It works! After installing Qt 4.7.1 and Qt Mobility 1.1 final, I was able to run the example QML video element with qmlviewer. As for LD_LIBRARY_PATH, I am on ubuntu and setting the path as instructed in the installation instructions (.profile) does not work for Ubuntu. I went the ld.so.conf.d route instead. I guess that worked. interesting that the .pro file was not necessary to get the example working.
Anyway, it looks like I finally get to have some fun with QML. Thanks for the help and suggestions.

@Andre I had same issue on Windows. There was another thread in the forum discussing the same issue but the last time I checked there was not any solution.
In my case, I just gave up Qt Mobility and used VLC with some own binding between QML and VLC. It worked for me as I only needed to play video w/o any overlay QML stuffs on top of video.

[quote author="Andre" date="1288082191"]Isn't it a bit strange that you need Qt Mobility to make multimedia work on the desktop? [/quote]
I think of QtMobility more of taking advantage of extra hardware (that not every device has) - in most cases these are things desktops don't have but mobile devices do.
But, video is a bit different. Everything can and should play that. I think the reason why it is separate is it shares a lot of code with other mobility pieces (video record?) and is commonly required for mobile applications. In the past, Qt devs have used other things (like VLC mentioned above).

Could you give some more details on that?
I am trying to play some video (also don't need to overlay QML on top) using MPlayer, but so far I am not having much luck. Playing using VLC sounds like a good option! -

Well, I still think it is a weird choice. My guess is that it allowed for a faster development outside the main Qt branch. Recording video is equaly valid on non-mobile devices. Think of using a webcam for instance. Most of the other API in QtMobility I totally get being in there. Not many desktops or laptops have too many sensors or are equiped with localization hardware after all, but multimedia needs to be available and Just Work (TM) on all supported platforms, I think. -
Hi, moo1 and Andre! There was a huge bug in QtMobility "http://bugreports.qt.nokia.com/browse/QTMOBILITY-583":http://bugreports.qt.nokia.com/browse/QTMOBILITY-583. To fix it try to apply patch from here: "http://bugreports.qt.nokia.com/browse/QTMOBILITY-783":http://bugreports.qt.nokia.com/browse/QTMOBILITY-783. I've applied this patch and now qml video component works just fine.
