CedarX是Allwinner发布的专有多媒体框架，不受linux-sunxi社区的支持。

它是负责硬件加速视频和音频解/编码（CedarV + CedarA）以及硬件块的专有软件库的名称。至于音频，硬件ACE（音频编解码器引擎）似乎只存在于A10和更早的SoC中。Allwinner重构了他们的专有用户空间库并部分地在GPLv2下发布它们，将它们命名为“media-codec”，而一些编解码器仍然只能作为类似插件中链接的专有二进制blob。
围绕该库许可的争议[1] [2] [3] [4]引起了一些压力之后 ，Allwinner发布了一个名为Sunxi-CedarX的新媒体编解码库[5] ，这是一个到目前为止的改写只有部分实现了一些编解码器作为开源，让其余的编解码器和功能这样的编码依赖于一个封闭的源插件二进制文件。

Allwinner的CedarX技术和库：

众所周知，Allwinner自己的CedarX专有库没有明确的使用许可，因此即使某些版本的源代码可用，开源软件中的使用条款也是未知的。Allwinner正在慢慢努力解决这个问题。
