how use start a ffmpeg via pm2?anyone can help?

What's going wrong?

i want use pm2 to run this cmd ffmpeg -i rtsp://XX:XXX@192.168.1.21:554/Streaming/Channels/101?transportmode=unicast -rtsp_transport tcp -f rtsp rtsp://127.0.0.1:554/01 the following is my script:

module.exports = {
  apps : [{
    name:'ffmpeg',
    exec_interpreter:'ffmpeg',
    args: '-i rtsp://xxx:xxxx@192.168.2.47:554/Streaming/Channels/101?transportmode=unicast -rtsp_transport tcp -f rtsp rtsp://127.0.0.1:554/01',
    watch: 'flase',
    autorestart:true,
    error_file:'./ffmpeg-err.log',
    out_file:'./ffmpeg-out.log',
    pid_file:'./ffmpeg-pid.log'
  }],
}

and the console give me:

[PM2][WARN] Applications ffmpeg not running, starting...
[PM2][ERROR] Error: No script path - aborting

but i just want to run a cmd not a script, so i dont have an script file.
need help,thx.

The issue includes a PM2 ecosystem configuration and an ffmpeg command, but names no repository file or test. Start with PM2's command and ecosystem-configuration documentation, then verify how a non-script command is represented; done means the supported usage is clearly documented and avoids the reported "No script path" error.
