Ubuntu 12.04下安装Gstreamer

http://blog.csdn.net/tiger99111/article/details/22196957



一. Gstreamer安装:

方法一:使用sudo apt-get install 安装

sudoapt-get install libgstreamer0.10-dev gstreamer-tools gstreamer0.10-toolsgstreamer0.10-doc
sudo apt-getinstall gstreamer0.10-plugins-base gstreamer0.10-plugins-good gstreamer0.10-plugins-ugly gstreamer0.10-plugins-badgstreamer0.10-plugins-bad-multiverse

 

方法二:在官方网站下载源码包,使用./configure, make, makeinstall进行安装:

官方网址:http://gstreamer.freedesktop.org

另外此网址有介绍链接各资源:http://gstreamer.freedesktop.org/news/,可直接下载tarballs

gstreamer-1.2.2.tar.xz, gst-plugins-base-1.2.1.tar.xz, gst-plugins-good-1.2.2.tar.xz,gst-plugins-ugly-1.2.2.tar.xz或者在列表中选择历史release版本下载

 

基础包下载:

Gstreamer-0.10.35.tar.bz2

http://gstreamer.freedesktop.org/src/gstreamer/

 

gst-plugins-base-0.10.35.tar.bz2

http://gstreamer.freedesktop.org/src/gst-plugins-base/

 

gst-plugins-good-0.10.30.tar.bz2

http://gstreamer.freedesktop.org/src/gst-plugins-good

 

gst-plugins-ugly-0.10.10.tar.bz2

http://gstreamer.freedesktop.org/src/gst-plugins-ugly/

 

安装过程中可能出现以下错误:

1. configure: error: Could not find bison

admin@ubuntu:$sudo apt-get install bison

 

2. configure: error: Could not find flex

admin@ubuntu:$sudo apt-get install flex

 

3. configure: error: *** Working zlib libraryand headers not found ***

admin@ubuntu:$sudo apt-get install zlib1g

 

Gstreamer-0.10.35配置成功后出现以下消息:


然后make, make install即可

接下来依次安装gst-plugins-base-0.10.35, gst-plugins-good-0.10.30,此时需注意安装顺序,必须先安装gst-plugins-base-0.10.35,再安装gst-plugins-good-0.10.30,此顺序不可修改,否则出现依赖错误。

以上包安装完成后使用:

gst-launch-vm audiotestsrc ! audioconvert ! audioresample ! osssink

可测试到耳机出现蜂鸣声。

 

二. Gstreamer测试播放mp3音乐:

需要使用mad解码插件,因此需要先安装gstreamer0.10-plugins-ugly,它依赖其他两个库。

admin@ubuntu:$ apt-get installliblid3tag0-dev

admin@ubuntu:$ apt-get install libmad0-dev

admin@ubuntu:$apt-get install gstreamer0.10-plugins-ugly

 

编译测序程序:

#include <gst/gst.h>
#include <glib.h>
//定义消息处理函数,
static gboolean bus_call(GstBus *bus,GstMessage *msg,gpointer data)
{
    GMainLoop *loop = (GMainLoop *) data;//这个是主循环的指针,在接受EOS消息时退出循环
    switch (GST_MESSAGE_TYPE(msg))
    {
        case GST_MESSAGE_EOS:
            g_print("End of stream\n");
            g_main_loop_quit(loop);
            break;
        case GST_MESSAGE_ERROR:
        {
               gchar *debug;
               GError *error;
               gst_message_parse_error(msg,&error,&debug);
               g_free(debug);
               g_printerr("ERROR:%s\n",error->message);
               g_error_free(error);
               g_main_loop_quit(loop);

                break;
        }
        default:
             break;
    }
    return TRUE;
}

int main(int argc,char *argv[])
{
    GMainLoop *loop;
    GstElement *pipeline,*source,*decoder,*sink;//定义组件
    GstBus *bus;

    gst_init(&argc,&argv);
    loop = g_main_loop_new(NULL,FALSE);//创建主循环,在执行 g_main_loop_run后正式开始循环

    if(argc != 2)
    {
        g_printerr("Usage:%s <mp3 filename>\n",argv[0]);
        return -1;
    }
    //创建管道和组件
    pipeline = gst_pipeline_new("audio-player");
    source = gst_element_factory_make("filesrc","file-source");
    decoder = gst_element_factory_make("mad","mad-decoder");
    sink = gst_element_factory_make("autoaudiosink","audio-output");

    if(!pipeline||!source||!decoder||!sink){
        g_printerr("One element could not be created.Exiting.\n");
        return -1;
    }
    //设置 sourcelocation 参数。即 文件地址.
    g_object_set(G_OBJECT(source),"location",argv[1],NULL);
    //得到 管道的消息总线
    bus = gst_pipeline_get_bus(GST_PIPELINE(pipeline));
   //添加消息监视器
    gst_bus_add_watch(bus,bus_call,loop);
    gst_object_unref(bus);
    //把组件添加到管道中.管道是一个特殊的组件,可以更好的让数据流动
    gst_bin_add_many(GST_BIN(pipeline),source,decoder,sink,NULL);
   //依次连接组件
   gst_element_link_many(source,decoder,sink,NULL);
   //开始播放
    gst_element_set_state(pipeline,GST_STATE_PLAYING);
    g_print("Running\n");
    //开始循环
    g_main_loop_run(loop);
    g_print("Returned,stopping playback\n");
    gst_element_set_state(pipeline,GST_STATE_NULL);
    gst_object_unref(GST_OBJECT(pipeline));
    return 0;
}

编译运行

gcc -Wall $(pkg-config --cflags --libs gstreamer-0.10) -g test2.c -o test2
./test2 /home/admin/mingyue.mp3
