Installation and Deployment

@shashi-prasad Qt does not use GStreamer on Windows, it is only used on Linux. On Windows it is different, see http://doc.qt.io/qt-5/qtmultimedia-windows.html Why do you want to use GStreamer on Windows? You just complicate things without any benefits.

@shashi-prasad I never used CMake to build Qt. Why don't you do in the way it is supposed to be built? configure make make install

Hi, Not likely the answer you expect but Qt is officially only supported with Apple's Xcode. You'll likely encounter other hurdle getting the build system to use another compiler.

@endr Well, then I don't know what exactly you need to install. Something with qt and mysql. On Ubuntu it is libqt5sql5-mysql package.

@shashi-prasad said in unable to Play mov and mp4 file using QT 5.6.0 in windows 10: Unresolved error code 80040266 compilation successful. Hi They changed how the back-end is selected. https://bugreports.qt.io/browse/QTBUG-51692

@JKSH Finally, QT is installed on CentOS 7.3, which has glibc-2.17 embedded. Thank you for all your help. If I have questions when using the tool, I will create a new post.

Hi and welcome to devnet, Can you explain the steps you did when the configuration/build failed ?

Hi and welcome to devnet, If you would like to follow Qt's releases then I'd recommend using the online installer, that way you can easily install several versions of Qt for several architectures and remove them as easily.

Hi, Isn't that basically the same question as [this thread](https://forum.qt.io/topic/81452/qt-based-player-in-window-based-on-direct-show/ ?

Qt Media Player example from the documentation.

That worked thanks !!

Hackish Solution to bypass the beta version problems: Go to Project Settings > VC++ Directories Add "$(QTDIR)\include" to include directories Add "$(QTDIR)\lib" to library directories Go to Linker > Input and add the desired library names to Additional Dependencies Qt53DAnimationd.lib Qt53DCored.lib Qt53DExtrasd.lib Qt53DInputd.lib Qt53DLogicd.lib Qt53DRenderd.lib for Debug Mode with the "d", for Release Mode without

The download is up again!

@this Usually, if you cross compile you have a sysroot. A sysroot is the file system of your target device containing all needed header files and libraries. That means: the path you use for wiringPi would usually be the one pointing to your sysroot. It looks like you have your sysroot under /mnt/rasp-pi-rootfs. Try (I assume you have wiringPi under /usr/local/lib on your RaspberryPi, correct the path if it is different): -L/mnt/rasp-pi-rootfs/usr/local/lib -lwiringPi

Hi, Take a look at the Linking the application to Qt as a framework chapter of the deployment documentation. It shows how to use macOS tools in order to deploy an application. You can use them in addition to macdeployqt when you have unusual stuff happening.

Hi and welcome to devnet, Please provide more information. What version of Qt did you use to build that project ? What Linux distribution are you running ? What is your graphic hardware ?

@roygbiv Yea that helps... you have 6 different gstreamers installed, lol. The chance you are linking to multiples just went up by quite a bit. ;) As for the -iname, it didn't seem to take that as a parameter to find. Which is weird since that has been in find since like ... forever. It's almost like you did find iname "gstreamer*" and missed the -iname based on the output you got. -iname is the same as -name except that it ignores case. I almost never use -name because of case issues in linux. :) Now if I had to guess I'm betting the culprits are the /usr/lib/x86_64 one and the /usr/local/lib one. They are different versions and a lot of people add /usr/local/lib to their LD_LIBRARY_PATH or ld.so.conf.
