• 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"
  }
}


  


  The error I'm getting on CloudWatch when trying to use FFprobe


  


  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.

  


• How to fix a webm file without audio ?

  14 juillet 2022, par John

  I use mediarecorder to record video and audio from a user's browser. We record every 15 seconds and then upload that blog to S3. Then we combine all the files together to make one webm file. I believe the first file isn't right because when I combine the files, there is not any audio - only video.

  


  Is there a way to alter the headers in the first file to use the audio in all of the subsequent files ? OR is there an FFMPEG command to force using the audio ? I know they exist in the other files.

  


  I don't believe this is important but here is the code that I use to save and combine the webm blobs.

  


  First I save the blobs from the media recorder

  


    recorder = new MediaRecorder(local_media_stream.remoteStream, {
               mimeType: encoding_options,
               audioBitsPerSecond: 96000,
               videoBitsPerSecond: bits_per_second,
            });
  recorder.ondataavailable = function(e) {
          that.save_blob(e.data, blob_index);      
         }


  


  Then later I combine each of those blobs.

  


  bucket = Aws::S3::Resource.new(region:'us-east-1').bucket("files")

keys = bucket.objects(prefix: "files").collect(&:key)

temp_webm_file = Tempfile.new(['total', '.webm'])
keys.each_with_index do |key, index|
    temp_webm_file.write bucket.object(key).get.body.read
end
temp_webm_file.close()


  


  One thing I know that fixes the issue is if I combine a short webm file with audio to the very beginning. Then the audio all works.
