• FFMPEG "Could find no file with path" and "No such file or directory"

  4 mai 2020, par bmw_58

  I try to convert a sequence of pictures to video file. 
But I get from ffmpeg the response, that no such file or directory

  



  Does someone have a solution for it ?

  



  My command line :

  



  ffmpeg -r 1/5 -start_number 0 -i "C:\Users\USER\Desktop\Pictures\%3d.png" -c:v libx264 -r 30 -pix_fmt yuv420p C:\Users\USER\Desktop\Pictures\out.mp4


  



  The error :

  



          C:\Users\USER>ffmpeg -r 1/5 -start_number 0 -i "C:\Users\USER\Desktop\Pictures\%3d.png" -c:v libx264 -r 30 -pix_fmt yuv420p C:\Users\USER\Desktop\Pictures\out.mp4

• ffmpeg to extract a video one frame per second ?

  10 juin 2015, par c2h2

  Currently I am using command line to extract pictures from video.

  ffmpeg -i ../m.mp4 -f image2 m.mp4-%04d.bmp

  This results too many frames.

  I would like to extract pictures from a video, one frame per second of video. Preferably with multithreading.

• 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
