Qt5.7.1支持gstreamer1.0

Qt5.7.1支持gstreamer1.0
为了能让qmultimedia使用gstreamer1.0，真的是煞费苦心，各种心酸苦辣，宝宝心里苦，可是宝宝不说。现在终于实现了，感觉好开心。ps，看老外网站说，5.8版本（beta）已经默认支持了gstreamer1.0，不过没测试。（balabala）

1.进入解压目录（enter decompression path）

执行下列语句（excute）
cd /opt/qt-everywhere-opensource-src-5.7.1/qtbase/
2.下载依赖（download the build dependencies）:
 
$ sudo apt-get install libfontconfig1-dev libfreetype6-dev libx11-dev libxext-dev libxfixes-dev libxi-dev libxrender-dev libxcb1-dev libx11-xcb-dev libxcb-glx0-dev
 
$ sudo apt-get install libxcb-keysyms1-dev libxcb-image0-dev libxcb-shm0-dev libxcb-icccm4-dev libxcb-sync0-dev libxcb-xfixes0-dev libxcb-shape0-dev libxcb-randr0-dev libxcb-render-util0-dev  
 
$ sudo apt-get install gstreamer1.0*
 
$ sudo apt-get install libgstreamer1.0*
 
$ sudo apt-get install libxcb-xinerama0-dev

3.configure
执行下列语句（excute）
./configure -gstreamer 1.0 

然后你就会看见gstreamer 1.0 yes，哈哈哈哈(congratulations，then you can see the gstreamer 1.0 yes)
4.make
执行下列语句（excute）
make -j 4 && sudo make isntall
5.坐等（hold on）
6.安装qtcreator4.2（install qtcreator4.2 form qt website）
刚开始以为，opensource会自带qtcreator，但是找啊找，都找遍了还是没找到，才知道，qtcreator是分开安装的。（at first ,I don't know qtcreator need to be install separately）

7.安装qtmultimedia和其他一些模块（install qtmultimedia） and others models

cd cd /opt/qt-everywhere-opensource-src-5.7.1/然后执行下边语句

for MODULE in qtimageformats qtsvg  qtscript qtxmlpatterns qtdeclarative qtsensors qt3d qtgraphicaleffects  qtlocation qtmultimedia; do  cd $MODULE;  /usr/local/Qt-5.7.1/bin/qmake .;  make -j4;  sudo make install;  cd ..; done
注意的是qmake的位置，因为我在安装qt5.7时候没有自己指定安装路径，所以默认路径是/usr/local/Qt-5.7.1/bin/qmake，如果你的不是，请自己更改
8.运行qtcreator（open qtcretor（ide））
随便新建一个项目（new a project）

在左边Projects点击，（click the left Projects）

点击manage kits（click the manage kits）

点击qtversion，点击auto-detected,（click qtversion then click the auto-detected）

点击qtversion，选择/usr/local/Qt-5.7.1/bin/qmake（qtversion，select '/usr/local/Qt-5.7.1/bin/qmake' ）

9.找个播放器测试一下（test）
给个例子的地址吧（或者在welcome examples 搜video 最后一个即可）（serch in welcome examples，keyword “video” the last one）
如果qtcreator4 没有examples，这里我把他上传至百度网盘公开链接https://pan.baidu.com/s/1qXKLrcC（if you have not the examps，click here）
我试验了RMVB和mp4都支持，（support rmvb MP4，others no test）

QT creator 中添加gstreamer动态库

在.pro文件中添加

即可

Package Qt5GStreamerQuick-1.0 not found

Thanks, I have got one work around to solve "Project ERROR: Package Qt5GStreamerQuick-1.0 not found".

1. "Qt5GStreamerQuick-1.0" has dependency with "gstreamer-1". Download "gstreamer-1.6.3" and perform make then make install.

2. Download the qt-gstreamer code, extract freshly and navigate to extracted folder. In my case it is

   cd ~/home/manojsahu/qt-gstreamer-1.2.0/ cmake CMakeLists.txt then make then sudo makeinstall Image of the qmlplayer built

Now the example qmlplayer gets built. But facing error "Failed to create qtvideosink. Make sure it is installed correctly". Perhaps It did not installed properly. Any workaround to build completely would be appreciated highly.
