} HevcNaluType; 当拿到H264裸流时，可以很容易解析到sps、pps。可以参考https://github.com/leixiaohua1020/simplest_librtmp_example.git雷神的基于librtmp h264的rtmp流实现。
根据H265 NAL Type解析出来H265的vps、pps、sps等信息之后，要做的就是把H265的流数据打包成rtmp格式。
支持h265转发的nginx：
https://github.com/illuspas/nginx-rtmp-win32
高人编译的win下的nginx，已经支持h265的rtmp，hls未使用
rtmp 和hls中的h265 的ID为 12
nginx rtmp模块源码，支持h265：
https://github.com/adwpc/nginx-rtmp-module
h265 的 rtmp封包：
