pingos exec_pull参数 执行问题

[sincez]

由于想通过exec_pull 来动态拉流转rtmp，我这边前端请求hls2的流地址的时候，追加了uri参数，但是拉流一直不成功，不知道是神什么原因，前端请求的m3u8地址为：http://127.0.0.1:8080/hls2/test.m3u8?uri=openUrl/IoAs24w nginx记录的错误日志，提示应该是报错，但是看不到实际执行的命令，不知道是哪里出错了，手动使用ffmpeg命令的时候是正常的，但是放到exec_pull里面，就会执行失败，不知道设么原因，麻烦帮看下什么原因呢？我这还有个问题，http-flv的流，一直请求不成功，实在找不到什么原因，也请帮忙看下，谢谢🙏，下边是我的nginx配置文件 `#user root; master_process on; worker_processes auto; #worker_rlimit 4g;

排查一下ffmpeg的安装路径，最好在/usr/bin 和 /usr/local/bin 两个目录里都添加ffmpeg工具，有些情况下可能查找的ffmpeg目录不一样
