<p>VideoToolbox框架具备iOS和macOS的硬件加速视频编码和解码功能。查看官方文档，VideoToolbox可以压缩视频、解压缩视频数据、转换视频数据、配置会话、多径压缩等等功能，自己对这个框架了解的程度还很浅，平时用到的也比较少，以后还得多发时间研究研究。另外iOS8开始，苹果才开放了硬解码和硬编码API，也难怪目前很多直播都只支持iOS8以上。<br>

<p> 最近利用空余时间研究了一下音视频采集，为方便项目的参考，特意做个笔记记录。用到AVCaptureSession来进行音视频数据采集，AVCaptureSession是用来管理视频与数据的捕获,采集到音频原始数据pcm(pcm是指未经过压缩处理的)压缩为aac格式，采集到yuv420格式的视频帧压缩成h.264格式。<br>链接: <a href="https://github.com/oopsr/AVDecode">demo链接</a></p>
