qt-extended 中如何支持gstreamer 播放引擎（ubuntu)

刚刚想了解下，在板子上的qt文件系统里头，怎么装一个自己的软件，然后移植。

从来没做过这个过程。搜索到这个文章，感觉挺有用的。以gstreamer 为例子。



1.ubuntu系统 安装gstreamer 依赖的库文件。

2 qt-extended的配置： 让gstreamer 被配置到。

../qt-extended-4.4.2/configure -mediaengines gstreamer

3.编译qt-extended



4.运行 qt-extended



qt-extended的Documents目录

我还尝试了下，安装automake，据说这个可以自动生成makefile文件。

以上过程，说明了cn99比srt好，应该放在前面。

两个条件

首先，需要系统里有gstreamer的开发库文件,在ubuntu中安装过程如下

sudo apt-get install libgstreamer0.10-dev
sudo apt-get install libgstreamer-plugins-base0.10-dev

其次，需要在配置编译过程中将gstreamer的选项使能。
../qt-extended-4.4.2/configure -mediaengines gstreamer

这样就可以编译带gstreamer的qt-extened了。

./bin/qbuild
./bin/qbuild image

在你运行qt-extended主程序的时候，如果你的Documents目录下有媒体文件，
那么进入媒体播放器找到你的媒体文件了

./bin/runqtopia

此时可能还不能播放，你需要安装gstreamer不同媒体格式的codec,比如mp3就是

sudo aptitude install gstreamer0.10-fluendo-mp3

若想知道还有哪些插件，可以用下面命令查看

aptitude search gstreamer|grep plugin

—————————————————————-
附:如果刚装好的ubuntu系统，希望能编译qt-extend-4.4 以后版本的话.
有几个先决条件.
1.最好先装好 qt-x11-4.4 以后的版本
2.一些必要的开发工具需要装

sudo apt-get install gcc g++ automake
sudo aptitude install libx11-dev libxtst-dev libxext-dev
sudo aptitude install libpng-dev
