博客介绍添加新数据类型支持的方法，先编写理解文件类型解析的文件格式插件，再编写从文件格式插件获取数据包并‘渲染’的渲染插件。以音频为例，‘渲染’指解码数据包并写入音频服务接口。还提及添加插件时会问的问题及调试方法。
You're on the right track. To add support for a new datatype,
you first write a fileformat plugin which understands how
to parse the file type. Then you write a rendering plugin
which knows how to take the packets from the fileformat plugin
and "render" them. In the case of audio, "rendering" would
mean decoding the packets and writing the decoded audio to
the audio services interfaces.
These are usually the questions I ask when adding
new fileformat and renderer plugins:
Did the fileformat get invoked when you tried to
play the sample files? If so, did it produce packets and were
those packets received by the renderer plugin? Both of these questions
can be answered by just running in a debugger.
