在嵌入式端使用metartc whip推流阿里云的直播服务时，遇到的一些问题

代码中的yang_http_post不支持ssl，线上环境基本都是ssl的，我使用libcurl来请求阿里云的whip接口
阿里云的直播服务whip要求上传的sdp里面的msid必须为指定的两个值，rtc audio/rtc video, 通过修改源码编译后可以获取sdp信息
阿里云的whip接口返回的sdp信息中的部分字段长度很长，例如ufrag，超过100个字节，代码里面的有些地方只为一些字段分配了64甚至更少的内存，运行时会崩溃
改完以上几点问题后可以成功推流阿里云低延迟RTS直播服务，并且正常播流。感谢您的开源项目
