GStreamer学习计划

http://blog.csdn.net/ds1130071727/article/details/78751596 GStreamer建议的学习步骤和网页链接汇总

GStreamer学习阶段        
1).学习《GStreamer讲解》ppt入门  
2).学习《GStreamer中文开发手册.pdf》，这时结合《GStreamer基础教程》和《GStreamer播放教程》来看    
3).深入理解应用开发，参考《gstreamerMP3播放器项目》写一个项目试试手(可省)
4).在学习插件编写之前，先学习GObject，教程有《GObject教程1，2，3》，学习完这三个教程以后，应该就
对GObject的规则有一个深刻的认识，然后就可以查看插件的源码，同时结合《gstreamer插件开发手册.pdf》来学习。

5).查阅官方英文文档进一步学习,边学边写

GStreamer offical file directory：
Introduction(Perface/Foundations)
The Basic of Writing a Plugin:
Constructing the Boilerplate
Specifying the pads
The chain function
The event function
The query function

Clocking
Quality Of Service (QoS)
Supporting Dynamic Parameters
Interfaces
Tagging (Metadata and Streaminfo)

Creating special element types:
Pre-made base classes
Writing a Demuxer or Parser
Writing a N-to-1 Element or Muxer
Writing a Manager


study a52dec plugin:
study gstaudiodecoder.c
gstaudiodecoder.c (在plugins-base目录下)
a52dec plugin code(在plugins-ugly目录下)
a52dec 继承于 gstaudiodecoder.c里面的东西
喂了把我们的东西加在gstreamer里面，你就要模仿写，全部自己写，没得必要，而且麻烦
看gstaudiodecoder.c和a52dec plugin的时候，注重理解里面的逻辑

gstbase_class->start = GST_DEBUG_FUNCPTR (gst_a52dec_start);
gstbase_class->stop = GST_DEBUG_FUNCPTR (gst_a52dec_stop);
gstbase_class->set_format = GST_DEBUG_FUNCPTR (gst_a52dec_set_format);
gstbase_class->parse = GST_DEBUG_FUNCPTR (gst_a52dec_parse);
gstbase_class->handle_frame = GST_DEBUG_FUNCPTR (gst_a52dec_handle_frame);

a52dec.c主要就是重写了这几个函数,我们到时也要重写这几个函数,也许更多
