• FFMPEG spawn promise not resolving

  24 décembre 2020, par fitzmode

  I have a problem where running ffmpeg with spawn using the event listener API for close or exit events works fine but when I try to convert spawn into a Promise it does not resolve.

  


  I'm

  


  This works fine

  


   const ls = spawn(ffmpeg_static.path,`-i movie.mov movie.mp4`.split(" ");

    //Listen for processing close
  ls.on("close", (code) => {
        console.log(`child process exited with code ${code}`);
        
     });



  


  function pspawn(args) {
 
  // *** Return the promise
  return new Promise(function (resolve, reject) {
 
    const process = spawn(ffmpeg_static.path, args);
//Listen for close and resolve.
    process.on("close", function (code) {
    
      resolve("Complete");
    });
    process.on("error", function (err) {
       // *** Process creation failed
       reject(err);
    });
  });
}

... 

async function run () {
await pspawn(['-i', 'movie.mov','movie.mp4'])
}


  


  I might be missing something simple but can't seem to figure out what it is.

• Trigger exec_pull on http connection

  29 octobre 2019, par M. Cole

  Is it possible to trigger exec_pull on http connection ? For example, I have the following Nginx configuration :

  server {
  
  
  
   listen 80;
  
  
  
  location /hls {
  
  
  
    types {
  
      application/vnd.apple.mpegurl m3u8;
  
      video/mp2t ts;
  
    }
  
  
  
                    root /mnt;
  
                    add_header Cache-Control no-cache;
  
                    index index.m3u8 index.ts;
  
                    add_header Access-Control-Allow-Origin *;
  
              }
  
          }
  
  
  
  }
  
  
  
  rtmp {
  
  
  
      server {
  
          listen 1935;
  
          allow play all;
  
  
  
  application hls {
  
  
  
  live on;
  
  exec_options on;
  
  
  
  exec_pull /usr/bin/ffmpeg -re -i http://example.com:333/293.m3u8 -c copy -f flv rtmp://localhost:1935/hls/$name;
  
  }
  
  
  
  application hls {
  
  
  
      live on;
  
      hls on;
  
      hls_path /mnt/hls;
  
      hls_fragment 3s;
  
  }
  
  
  
       }
  
    }

  I would like to have an exec_pull triggered on HLS http request.
  For example If I request http://my-serverip.com/hls/293.m3u8 then it should start ffmpeg to start creating hls files.

  I’ve been working on this for 5-6 days and could not figure out how to trigger exec_pull on http requests.
