  • Initialisation de MediaSPIP (préconfiguration)

    20 février 2010, par

    Lors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
    Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
    Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.
    Dans un premier temps il active ou désactive des options de SPIP qui ne le (...)

  • ffmpeg streaming on embedded device [closed]

    18 février 2012, par JoeFrizz

    I have a problem with the ffmpeg streaming application.

    When I try to dump a RTSP (mp4) stream to a file on my
    desktop (Ubuntu) everything works fine...

    What I actually want to do is to download the same stream
    with an embedded system (very limited CPU power)...

    While I get about 150 fps on the desktop my embedded system loads
    about 2 fps only and struggles after downloading
    of approx. 150 frames. All the other frames (about 1000 total)
    are dublicated or missing...

    Can this problem be fully explained by the weak CPU power
    of the embedded system ? Does the RTSP protocol allow streaming
    far below the normal rates (my desktop achieves) ?

    Are there any tricks to overcome that issue ?

  • 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
