二  编译
mkdir build
cd build
sudo cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/gtstreamer

-----------------------------------------------------------------------------
-- The following REQUIRED packages could NOT be located on your system.
-- You must install these packages before continuing.
-----------------------------------------------------------------------------
   * Boost (1.39 or higher)  <http://www.boost.org/>
     Required for building QtGLib
   * GStreamer (0.10.33 or higher)  <http://gstreamer.freedesktop.org/>
     Required to build QtGStreamer
   * GStreamer app library (0.10.33 or higher)  <http://gstreamer.freedesktop.org/>
     Required to build QtGStreamerUtils
   * GStreamer interfaces library (0.10.33 or higher)  <http://gstreamer.freedesktop.org/>
     Required to build QtGStreamer

-----------------------------------------------------------------------------

A 安装 boost
sudo apt-get install libboost-dev
sudo cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/gtstreamer
-----------------------------------------------------------------------------
-- The following REQUIRED packages could NOT be located on your system.
-- You must install these packages before continuing.

   * GStreamer interfaces library (0.10.33 or higher)  <http://gstreamer.freedesktop.org/>
     Required to build QtGStreamer

2 Gstreamer
为什么说Gstreamer没有安装呢？
只有这个库我是自己安装而没有采用apt-get install 的方法，就是因为这样而找不到这个库。
gedit ~/.branshrc
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
sourc ~/.branshrc

运行命令查看：
pkg-config --libs  gstreamer-1.0
-L/usr/local/lib -lgstreamer-1.0 -lgobject-2.0 -lglib-2.0 
这样能找到，所以路径配置已经是没有问题了。
pkg-config --libs  gstreamer
Package gstreamer was not found in the pkg-config search path.
Perhaps you should add the directory containing `gstreamer.pc'
to the PKG_CONFIG_PATH environment variable
No package 'gstreamer' found
这样是找不到的。
安装文件是安装在usr\lib 下面的。
usr\lib\pkgconfig 
目录usr\lib 下面有gstreamer-0.10但是
pkg-config --libs  gstreamer-0.10
也是找不到的。

将qt-gstreamer-0.10.2\cmake\modules\的gstreamer的版本改为1.0.
从新编译
checking for module 'gstreamer-interfaces-1.0'
--   package 'gstreamer-interfaces-1.0' not found
* GStreamer interfaces library (0.10.33 or higher)  <http://gstreamer.freedesktop.org/>
     Required to build QtGStreamer

那个这个gstreamer-interfaces是只那个gstreamer组件呢？应该是我没有安装这个组件导致的。
不清楚是那个组件了！
安装组件gst-plugins-ugly 还是不可以！这个到底是那个组件呢？
网上查找了一下，应该是在gst-plugins-base组件里面的。
应该四0.10的版本有，单色1.0的版本就没有了！

我还算用0.10的版本从新编译一个好了！
1 安装0.10的版本
sudo apt-get install gstreamer0.10 
报错：
gstreamer0.10-fluendo-plugins-mp3-partner : 冲突: gstreamer0.10-fluendo-mp3
先卸载它好了：
sudo apt-get remove gstreamer0.10 
sudo apt-get install gstreamer0.10 
还是不行

下载源代码，编译运行。

2 再次编译看
A sudo cmake .. -sudo cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/qtgtstreamer
-----------------------------------------------------------------------------
-- The following external packages were located on your system.

3 测试
A 
sudo gst-launch-0.10 -v playbin uri=file:///home/hdhuang/realize.ogg
ok可以正常播放。
B examples
要在控制台使用sudo ./player 运行。
可以出声音，但是视频有问题，估计是编译时候渲染出问题了，从新编译一下渲染。
C 安装opengl
sudo apt-get install libqt4-opengl-dev

还是没有图形呢？

4 安装路径有点问题

从新安装一下：

sudo cmake .. -sudo cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/

sudo make

sudo make install

rm -rf build

mkdir build

cmake .. -DCMAKE_INSTALL_PREFIX=/opt/EmbedSky/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/tq-linaro-toolchain/ -DCMAKE_BUILD_TYPE=Release -DQT_VERSION=5
make

make install
