QtMultimediaKit QtMobility

[beowulf]

I'm trying to create a video player, looking for references on the internet I found the Phonon, but reading much, searching much, I realized that he is slowly dying, so I decided to find another solution. I found the QtMultimediaKit QtMobility, but unfortunately I can not find anything on the internet to help me with them, not even the documentation is helping.

Can anyone give me an example of how to play a mp4 video? Thank you.

Check the "Qt Mobility Media player example app":http://doc.qt.digia.com/qtmobility/player.html.

When i try to compile this example, i got that message:

c:\qtsdk\examples\qtmobility\player\player.h:46: error: C1083: Cannot open include file: 'qmediaplayer.h': No such file or directory

I can not fix the error, I got tired of searching the internet and found no similar problem.
According to Qt, Qt Mobility comes with Qt SDK, but still is not working.

@c:\qtsdk\examples\qtmobility\player\player.h:46: error: C1083: Cannot open include file: ‘qmediaplayer.h’: No such file or directory@

Try editing player.pro:
@
// Change this...
QT += network
xml

// ...to this:
QT += network
xml
multimedia
@

Looks like the Mobility examples from QtSDK 1.2.1 are broken. Other people have this problem too (e.g. http://qt-project.org/forums/viewthread/7724 )

One easy hack is to go to C:\qtsdk (or wherever you installed it), search for the .h files that your SDK can't find (qmediaplayer.h and qmobilityglobal.h, from your screenshot), and add the folder(s) to player.pro like this:
@
INCLUDEPATH += C:/qtsdk/include/QtMultimediaKit
INCLUDEPATH += C:/qtsdk/include/QtMobility
@

Notes:

Use '/' instead of '', even in Windows

The above is an example only -- check your folders for the correct path

There is no a folder with the libraries, only those.

I've included the directory but appears more errors.

@INCLUDEPATH += C:/QtSDK/Simulator/QtMobility/msvc2008/include/QtMobility
INCLUDEPATH += C:/QtSDK/Simulator/QtMobility/msvc2008/include/QtMultimediaKit@

I reported the bug: https://bugreports.qt-project.org/browse/QTMOBILITY-2078

Have you seen http://qt-project.org/wiki/QtMediaHub ?
Note that in Qt5, QtMultimedia is an add-on module to Qt itself, rather than a module of QtMobility.

[beowulf]

Never seen the QtMediaHub, but from what I saw he did not serve to my project.

I want a video player that supports most formats, such as VLC.

No need to install codecs on the computer user, but with the libraries folder within the video player, like VLC, which has all the libraries for the different formats.

[JKSH]

Qt doesn't natively support many multimedia formats. If you want that, you should use a 3rd-party library -- if you link libVLC to your project, you can play all the formats that VLC media player can play.
