有以下几种选择：
GStreamer 是用于构建媒体处理组件图形的跨平台库。它支持的应用范围从简单的Ogg / Vorbis播放，音频/视频流到复杂的音频（混合）和视频（非线性编辑）处理。
GStreamer is a cross-platform library for constructing graphs of media-handling components. The applications it supports range from simple Ogg/Vorbis playback, audio/video streaming to complex audio (mixing) and video (non-linear editing) processing.
本页在GStreamer和MP3格式上有一些非常有趣的信息，如果你决定使用GStreamer，那么它是必须阅读的：

MP3音频格式是一种痛苦。它是专利保护，使得Linux分销商难以在世界各地合法地封装（或Linux用户使用）。它甚至听起来不错，相比一些替代品。但是MP3很难避免;
The MP3 audio format is a pain. It is patent-encumbered, making it hard for Linux distributors to package (or Linux users to use) legally in various parts of the world. It doesn't even sound all that good, compared to some of the alternatives. Yet MP3 is hard to avoid;
除此之外，Gstreamer通过 gst-launch 这对于测试您在程序中组装的管道非常有用，然后开始编写代码实际代码：
Besides that, Gstreamer ofers a command-line interface through gst-launch which is very useful to test the pipeline you are assembling in your program before you start to write code the actual code:
gst-launch filesrc location=/path/to/audiofile ! decodebin ! oss4sink
