• Youtube-dll how to get a direct download link to the merged file without creating a temp file on server

  11 juillet 2019, par CeylonDomains Solutions

  Is there any way to create a direct download link to the merged file without creating a temp file on the server in youtube-dll ?

  youtube-dll -f 255+160 https://youtu.be/p-flvm1szbI 

  The above code will merge the file and output the merged file.

  I want to allow users to directly download the merged file to their computers — without creating any temp file on my server. Is this possible ?

  (Creating a temp file and then letting the user download it is already possible.)

• Download,modify and upload video with S3

  9 février 2017, par Gold Fish

  I’m trying to write a Lambda function in nodejs that will download a file from S3 bucket, modify it, and then upload it back to another S3 bucket. For some reason, the algorithm prints the ’Modify Video’ log and then finishes and exit without error. What am I doing wrong ?

  var AWS = require('aws-sdk');
  
  var util = require('util');
  
  var ffmpeg = require('fluent-ffmpeg');
  
  var s3 = require('s3');
  
  
  
  // get reference to S3 client
  
  
  
  var awsS3Client = new AWS.S3();
  
  var options = {
  
    s3Client: awsS3Client,
  
  };
  
  var client = s3.createClient(options);
  
  
  
  exports.handler = function(event, context, callback) {
  
      // Read options from the event.
  
      console.log("Reading options from event:\n", util.inspect(event, {depth: 5}));
  
      var srcBucket = event.Records[0].s3.bucket.name;
  
      // Object key may have spaces or unicode non-ASCII characters.
  
      var srcKey    =
  
      decodeURIComponent(event.Records[0].s3.object.key.replace(/\+/g, " "));
  
      var dstBucket = srcBucket + "-dst";
  
      var dstKey    = "mod_" + srcKey;
  
  
  
      var dwnld_file_name = '/tmp/vid.mp4';
  
      var mdfy_file_name = '/tmp/mod_vid.mp4';
  
  
  
      // Sanity check: validate that source and destination are different buckets.
  
      if (srcBucket == dstBucket) {
  
          callback("Source and destination buckets are the same.");
  
          return;
  
      }
  
  
  
      // Infer the video type.
  
      var typeMatch = srcKey.match(/\.([^.]*)$/);
  
      if (!typeMatch) {

• Concatenate a video and audio stream via urls and download them directly to user's computer

  10 juillet 2019, par CeylonDomains Solutions

  I’m looking for a solution for the following matter.

  I need to concatenate a video and an audio stream via URL and then download them directly to user’s computer without creating a merged file on server. Is there any possible way to do this via ffmpeg or any other tool ?

  Merging 2 files on server and then downloading this file to user’s computer is possible, but I’m expecting something more than that.

  Please note my application is a PHP application.

  Thanks in advance.
