S60设备支持的音视频解码概览
手机的音视频解码分为软解码和硬解码，symbian对mp3,aac,amr的支持比较全，本地文件播放/录制/流媒体播放都OK，而wma作为微软主推的音频格式，symbian就没那么友好了，只用CMMFCodec实现了本地文件的软解码。以下是S60 3版所有的音视频编码格式， 搞相关方向的赶紧收藏:)
Codecs in S60 Devices
Different S60 devices may have different multimedia codecs. There are similarities between S60 devices, but there are differences, as well. The mere presence of a codec (e.g. mp3) in a device does not tell too much to developers. We need to know what APIs can be used to access that codec.
This page has several purposes:
- Show which codecs are in different S60 devices (3rd edition) and what are the APIs through which they can be accessed
- Provide an application to check this info for upcomming S60 phones.
For the theory behind the tables, please take a look on the following articles and documents:
- S60 Multimedia in FN
- MMF Architecture
- Image and Video capturing

[edit] FAQ
Q: I know that Device X has the codec Y, but the codec is not listed in the tables above. Why?
A: This is because the codec can not be accessed by any of the APIs listed in the tables.
