• 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.

  


• Unable to get nginx-vod-module plugin to work

  31 octobre 2020, par AAP

  My first time trying hands on nginx-vod-module or any video streaming for that matter.
I just want to play static mp4 videos which I place on the server but via hls instead of direct mp4 access. No actual live streaming

  


  Q1. Am I right in understanding that a mp4 video which I place locally on my server, will automatically get broken down into segments for HLS ?

  


  My nginx installation is here : /opt/kaltura/nginx
The mp4 file is placed at /opt/kaltura/nginx/test/vid.mp4

  


  In ../nginx/conf/server.conf, I have this :

  


  location /hls/ {
            alias test/;
            vod hls;
            vod_bootstrap_segment_durations 2000;
            vod_bootstrap_segment_durations 2000;
            vod_bootstrap_segment_durations 2000;
            vod_bootstrap_segment_durations 4000;

            include /opt/kaltura/nginx/conf/cors.conf;
        }
location / {
            root   html;
        }


  


  Now, I am able to access the m3u8 file :
curl http://104.167xxxxx/hls/vid.mp4/index.m3u8

  


  But when I try to open this file via VLC, I see these errors in errors.log :

  


  *2020/10/31 15:00:08 [error] 12749#0: *60 mp4_parser_validate_stsc_atom: zero entries, client: 49.207 ..., server: ubuntu, request: "GET /hls/vid.mp4/seg-1-v1.ts HTTP/1.1", host: "104.167. ..."
2020/10/31 15:00:08 [error] 12752#0: *61 mp4_parser_validate_stsc_atom: zero entries, client: 49.207 ..., server: ubuntu, request: "GET /hls/vid.mp4/seg-2-v1.ts HTTP/1.1", host: "104.167. ..."
2020/10/31 15:00:09 [error] 12749#0: *62 mp4_parser_validate_stsc_atom: zero entries, client: 49.207 ..., server: ubuntu, request: "GET /hls/vid.mp4/seg-3-v1.ts HTTP/1.1", host: "104.167. ..."
2020/10/31 15:00:10 [error] 12751#0: *63 mp4_parser_validate_stsc_atom: zero entries, client: 49.207 ..., server: ubuntu, request: "GET /hls/vid.mp4/seg-4-v1.ts HTTP/1.1", host: "104.167. ..."*


  


  Q2 : Is https must for this to work ?
Q3 : I dont see any /hls/vid.mp4 folder created anywhere on the server. Do I have to manually run ffmpeg separately to create the hls segments ?

  


  What wrong am I doing ?

  


• ffmpeg, twitch.tv, doesnt work

  7 novembre 2015, par John Smith

  Im using this command for streaming :

  ffmpeg -f dshow -i video="screen-capture-recorder" -f dshow -i audio="Mikrofon (USB audioeszköz)" -f dshow -i audio="virtual-audio-capturer" -f dshow -i audio="Mikrofon (Conexant SmartAudio H" -vcodec libx264 -r 25 -crf 0 -acodec aac -strict -2 -filter_complex amix=inputs=3:duration=first -pix_fmt yuv420p -s 640x480 -preset fast -f flv "rtmp ://live.twitch.tv/app/live_**********"

  if I save it to disk, it works. Streaming to twitch.tv also wont give error, but it just stays blank, it cannot see it "alive"
