• FFmpeg license for transcoding without distribution

  5 avril 2022, par Oualid Ramdani

  I am making a website (in a commercial context) where users can upload videos to our server
naturally that causes problems with browser compatibility. the solution would be to transcode them using FFmpeg on the server.
the problem is i have been reading on FFmpeg and it's license and i am very confused, does the use of FFmpeg on the server count as distribution ? and that is before talking about patented code.
if it is not possible to do it without risking the entire company in legal disputes. are there any alternatives that can be used ?
thank you very much

  


• Is it allowed to embed the ffmpeg.exe in my project ? [on hold]

  22 juillet 2019, par Snowy White

  I have written a program that, among other things, does some audio format converting. I use a library which in turn uses the ffmpeg.exe for this. So at the moment, the user needs to have ffmpeg in the same directory as the program itself. But what I would prefer is to add ffmpeg to my project as an embedded resource, so that the users don’t need to care about that. And now my question is, as I have seen that ffmpeg is licensed under LGPL, would it be legal to do so ? Or do the users explicitly have to get ffmpeg by themself ?
  Thank you for any answers in advance !

• FileNotFoundError on aws Lambda when concatenating videos with ffmpeg

  2 juillet 2021, par Shibu Menon

  Goal :

  



  

  • Concat 2 videos (both are in an s3 bucket) via aws Lambda using ffmpeg

  


  • Upload the resultant output.mp4 to another S3 bucket

  


  • Python 3+

  


  



  I've already created a layer containing a static ffmpeg

  



  The Error :

  



  {
  "errorMessage": "[Errno 2] No such file or directory: '/tmp/output.mp4'",
  "errorType": "FileNotFoundError",
  "stackTrace": [
    [
      "/var/task/lambda_function.py",
      19,
      "lambda_handler",
      "s3.Object(bucketLowRes, mp4OutputFileName).put(Body=open(new_file_key, 'rb'))"
    ]
  ]
}


  



  My Lambda function :

  



  import json
import os
import subprocess
import boto3

s3 = boto3.resource('s3')
bucketLowRes = s3.Bucket("bucket-conc-lowres")

def lambda_handler(event, context):
    # TODO implement

    mp4OutputFileName = 'output.mp4'

    new_file_key = os.path.abspath(os.path.join(os.sep, 'tmp', mp4OutputFileName))
    subprocess.call( ['/opt/ffmpeg', '-i', 'concat:s3://bucket-word-clips/00th76kqwfs915hbixycb77y9v3riwsj30.mp4|s3://bucket-word-clips/00uoakp6jyafbu13ycvl6w2i9tj42eux30.mp4', new_file_key ] )

    s3.Object(bucketLowRes, mp4OutputFileName).put(Body=open(new_file_key, 'rb'))

    return {
        'statusCode': 200,
        'body': json.dumps('Hello from Lambda!')
    }


  



  Question :

  



  

  • FileNotFoundError : Where is the output mp4 file of my ffmpeg concat being saved ??

  


  • And if it is being saved to /tmp/output.mp4 , then why the FileNotFoundError ??

  


  



  thanks
