在 Web 端进行软解码首先会想到使用 JavaScript。libde265.js 是用 C 开发的开源 H.265 编解码器 libde265 的 JavaScript 版本(确切地说是 libde265 的 asm.js 版本，后面会说明)。经测试，使用 libde265.js 并不是一个音视频播放的完善方案，存在帧率偏低和音视频不同步等问题。此外，JavaScript 作为解释型脚本语言，对于 H.265 解码这种重度 CPU 密集型的计算任务而言，也不是理想的选择，于是继续探寻更优方案。

H265封装成TS流，查看openHEVC-ffmpeg-2.5源代码，及一些H265的TS流视频文件，基本的方式跟H264是一样的，这里主要注意的地方就是流类型不一样，H264的值为0x1b，H265的值为：0x24
