生成assetBinData压缩文件时，需要根据文件后缀判断是否需要压缩，媒体文件压缩后是无法正确加载的。

不压缩后依然加载不了，挪到StreamingAsset使用，更新后依然加载不了，使用UnityWebRequest从StreamingAsset加载二进制文件没问题，但是用Unity VideoPlayer组件的Url加载模式会加载不出来

研究了一下源码，问题应在hook只hook了libunity.so，视频的播放方式可能是libUnity.so获取文件描述符，然后给到Android底层，底层使用文件描述符去读取文件，但是libunity.so中返回的文件描述符不是真实的apk文件的文件描述符，所以底层直接读取文件是读取不到的，具体怎么修改，还没想好，作者大佬有没有什么好的解决方案？？

不打AB，不处理，直接放streaming里面，直接load streaming的出来播。变更的话，下载到随便一个目录，读出来播就是了

unity 的VideoPlayer不支持load streaming播放，现在临时的解决方案就是复制到包体外面，用外面的路径播放，但是不确定会不会有其他类似的问题，bug的本质是因为只Hook了libUnity.so的io接口，只要libUnity.so把文件句柄提供给其他部分使用都会有这种问题，感觉是个隐藏的坑啊，这个bug有什么本质性的解决方案么？

没， 没必要搞复杂，用最稳妥的方案，特例不多。我们之前时用streaming的，不行就复制到外面
