• Error : ffmpeg exited with code 1 on AWS Lambda

  16 juin 2022, par Hassnain Alvi

  I am using fluent-ffmpeg nodejs package to run ffmpeg for audio conversion on AWS Lambda. I am using this FFmpeg layer for lambda.
Here is my code

  


    const bitrate64 = ffmpeg("file.mp3").audioBitrate('64k');
    bitrate64.outputOptions([
        '-preset slow',
    '-g 48',
    "-map", "0:0",
        '-hls_time 6',
        '-master_pl_name master.m3u8',
        '-hls_segment_filename 64k/fileSequence%d.ts'
    ])
    .output('./64k/prog_index.m3u8')
    .on('progress', function(progress) {
        console.log('Processing 64k bitrate: ' + progress.percent + '% done')
    })  
    .on('end', function(err, stdout, stderr) {
        console.log('Finished processing 64k bitrate!')
    })
    .run() 


  


  after running it via AWS lambda I get following error message

  


  ERROR   Uncaught Exception  &#xA;{&#xA;    "errorType": "Error",&#xA;    "errorMessage": "ffmpeg exited with code 1: Conversion failed!\n",&#xA;    "stack": [&#xA;        "Error: ffmpeg exited with code 1: Conversion failed!",&#xA;        "",&#xA;        "    at ChildProcess.<anonymous> (/var/task/node_modules/fluent-ffmpeg/lib/processor.js:182:22)",&#xA;        "    at ChildProcess.emit (events.js:198:13)",&#xA;        "    at ChildProcess.EventEmitter.emit (domain.js:448:20)",&#xA;        "    at Process.ChildProcess._handle.onexit (internal/child_process.js:248:12)"&#xA;    ]&#xA;}&#xA;</anonymous>

  


  I don't get any more info so I am not sure what's going on. Can anyone tell me what's wrong here and how can I enable more detailed logs ?

  


• avformat/hls : Be more picky on extensions

  avformat/hls : Be more picky on extensions
  This blocks disallowed extensions from probing
  
  It also requires all available segments to have matching extensions to the format
  
  mpegts is treated independent of the extension
  It is recommended to set the whitelists correctly
  
  instead of depending on extensions, but this should help a bit,
  
  and this is easier to backport

• ffmpeg remote url not working in lambda function

  9 septembre 2024, par Komal

  I have created lambda function to trim video.

  


  I run this command :

  


  /opt/bin/ffmpeg -protocol_whitelist file,http,https,tcp,tls -i 'https://source-bucket.s3.amazonaws.com/1.mp4' -ss 5 -t 10 -loglevel 48 -y -avoid_negative_ts 1 -acodec copy /tmp/output.mp4


  


  It gives following output :

  So, its not going beyond this : 'Opening 'https://source-bucket.s3.amazonaws.com/1.mp4' ; for reading\n'

  


  And after this, it immediately gets out. Need suggestions, where its going wrong. Same command working fine on local computer.

  


  I tried cloudfront and signed url as well, as mentioned in this post : How to read remote video on Amazon S3 using ffmpeg. But it doesnt work with url. Only working when downloaded into tmp folder.

  


  Following is the final log, which you can see is no timeout. It actually finish function execution within 2-3 seconds. I have timeout set for 15 mins to the function which is maximum :
