• Struggling getting FFMPEG to work on Lambda function (Serverless Framework)

  3 juin 2022, par Red Vic

  I've been trying to get FFMPEG to work on my serverless framework for hours and I can't get to grasp how all this should work.

  


  This is my JavaScript code in the handler (just for testing purposes) :

  


  require("dotenv").config();

const ffmpegSync = (url) => {
  const ffmpeg = require("fluent-ffmpeg");
  ffmpeg.setFfprobePath("/opt/ffmpeg-layer/ffprobe");
  ffmpeg.setFfmpegPath("/opt/ffmpeg-layer/ffmpeg")

  return new Promise((resolve, reject) => {
    ffmpeg.ffprobe(url, async (err, metadata) => {
      if (err) {
        resolve(err);
      }
      console.log(metadata);
      resolve(metadata);
    });
  });
};

const ffmpegTeller = async (e, context) => {
  const AWS = require("aws-sdk");

  const s3 = new AWS.S3();
  AWS.config.update({
    accessKeyId: process.env.AWS_ACCESS_KEY,
    secretAccessKey: process.env.AWS_SECRET_KEY,
    region: "us-east-1",
  });

  const sourceBucket = e["Records"][0]["s3"]["bucket"]["name"];
  const sourceKey = e["Records"][0]["s3"]["object"]["key"];
  const signedUrlExpireSeconds = 60 * 5;

  const url = s3.getSignedUrl("getObject", {
    Bucket: sourceBucket,
    Key: sourceKey,
    Expires: signedUrlExpireSeconds,
  });

  await ffmpegSync(url).then((data) => {
    console.log(data);
    return {
      body: JSON.stringify(data),
      statusCode: 200,
    };
  });
};

module.exports = {
  ffmpegTeller,
};


  


  serverless.yaml :

  


  service: my-ffmpeg-api
frameworkVersion: '3'

provider:
  name: aws
  runtime: nodejs14.x
  region: us-east-1

functions:
  ffmpegTeller:
    handler: handler.ffmpegTeller
    events: 
      - s3:
          bucket: sourceBucket
          event: s3:ObjectCreated:*


  


  package.json

  


  {
  "dependencies": {
    "dotenv": "^16.0.1",
    "fluent-ffmpeg": "^2.1.2"
  }
}

  This is the view on the Lambda function page on AWS :

  


  

  


  I'd really appreciate some help. I'm really going mad. Thanks in advance.

  


• video rotation with ffmpeg doesn't work

  29 juillet 2013, par user737486

  I'm trying to rotate video using ffmpeg. The original video is rotated 270°. When I run the following command :

  ffmpeg -y -threads 4 -i IMG_3290.MOV -vcodec libx264 -preset faster -s 568x320 \
  
  -vf "transpose=2" -strict -2 -b 5000k -acodec aac -ac 1 -ar 16000 -ab 32000 \
  
  IMG_3290.MP4

  I got no error, but the output video is still rotated and contains the tag rotate: 270.

• Why does shell_exec into variable using PHP not work ? [on hold]

  13 août 2019, par omega1

  I am trying to run this but the variable $new is empty when I run it. When I run the ffmpeg command via command line it gives me the desired output, in fact when I run it in php I see the output from ffmpeg which I’m expecting to be put in the $new variable, but it’s empty. Can anyone help me with the reason ?

  Thanks.

  <?php
  
  $new = shell_exec('ffmpeg -t 10 -i http://audiostream.com -af "volumedetect" -f null /dev/null');
  
  file_put_contents('output.txt', $new);
  
  ?>
