librtmp h265 推流

h264和h265的区别：

h264和H265总的来说格式是一样的，H265多了一个VPS。

在解码H264时，sps、pps是必须的。而在解码H265时，sps、vps、pps是必须的。

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

nginx rtmp h264/h265 下载 https://github.com/illuspas/nginx-rtmp-win32

可以参考nginx.conf。原有的ok
