• Running Background Process using FFMPEG on Google Cloud Run stopping in middle

  7 juillet 2021, par pashaplus

  I have an external bash script that transcodes audio files using FFmpeg and then uploads the files to google cloud storage. I am using the google cloud run platform for this process but the process is stopping in the middle and not getting any clue from the logs. I am using the node js spawn command to execute the bash script

  


      const createHLSVOD = spawn('/bin/bash', [script, file.path, file.destination, contentId, EPPO_MUSIC_HSL_URL, 'Content', speed]);
    createHLSVOD.stdout.on('data', d => console.log(`stdout info: ${d}`));
    createHLSVOD.stderr.on('data', d => console.log(`stderr error: ${d}`));
    createHLSVOD.on('error', d => console.log(`error: ${d}`));
    createHLSVOD.on('close', code => console.log(`child process ended with code ${code}`));


  


  on cloud run beginning the process itself taking a lot of time but in my local machine transcoding and uploading is very fast. after some time transcoding logs are being stopped and no new logs appear. I have no clue what is happening

  


  

  


  so what is happening here ? why it is very slow in the first place and why the process is being stopped in middle without any error

  


  node js script
