  • How to combine/concatenate videos stored in AWS S3 bucket based on title of the file name

    9 juin 2020, par orangecube

    I am using a service that allows me to record videos that get automatically pushed to a folder (submissions) in an S3 bucket. There are multiple videos however they need to be grouped together and concatenated so the output is one video per group.

    



    So, basically, any tips on how I can take videos based on the title and stitch them together ?

    



    Example :

    



    Submissions folder will have :

    



    a-100-2.mp4
a-200-6.mp4
b-123-5.mp4


    



    Expected output in processed folder :

    



    a.mp4     - (both 'a' videos get stitched together)
b.mp4     - (only 'b' gets sent over since there is only one video.)


    



    Thanks in advance !

    



    Edit : Some additional and detailed information below if it helps.

    



    The files will be labeled with :
name-location-video_token-stream_token.mp4

    



    Need help creating a script or process that will concatenate the videos using the procedure outlined below :

    



    Processing rules (back end) :

    



      


    1. Check if videos have same video_token in ‘submissions folder’. If so, keep the newest one and delete old ones.

      2. 


    2. Take all videos in ‘submissions folder’ with same name and location in title and concatenate the videos. Save output video to a new folder in the bucket labeled as the location for the folder name. 
Output file name : 
name-location-year.mp4.

      3. 


    



    EXAMPLE :

    



    Submissions folder :
joey-toronto-001-354.mp4

    



    joey-toronto-001-241.mp4 - this will be deleted

    



    joey-toronto-103-452.mp4

    



    alex-montreal-352-232.mp4

    



    alex-montreal-452-223.mp4

    



    Resulting output :

    



    Toronto folder :

    



    Joey-toronto-2020.mp4

    



    Montreal folder :

    



    Alex-montreal-2020.mp4

    


  • How to create thumbnails of videos with Meteor, CollectionFS, & FFMPEG

    29 juin 2017, par Jared Martin

    I’m using Meteor with CollectionFS to store videos. I need a transform to create thumbnails of my videos.

    Videos = new FS.Collection("videos", {
    
  stores: [
    
    new FS.Store.FileSystem("thumbs", { 
    
      transformWrite: function(fileObj, readStream, writeStream) {
    
        // What goes here?
    
      }
    
    }),
    
    new FS.Store.FileSystem("videos"),
    
  ],
    
});

    I’ve worked out how to do this with ffmpeg :

    ffmpeg -i video.mp4 -vf  "thumbnail,scale=640:360" -frames:v 1 thumb.png

    But I’m not sure how to do this with the readStream I’m given and output the writeStream.

    Here’s an example of how it is done with images using GraphicsMagick :

    Images = new FS.Collection("images", {
    
  stores: [
    
    new FS.Store.FileSystem("thumbs", { 
    
      transformWrite: function(fileObj, readStream, writeStream) {
    
        // Transform the image into a 10x10px thumbnail
    
        gm(readStream, fileObj.name()).resize('10', '10').stream().pipe(writeStream);
    
      }
    
    }),
    
    new FS.Store.FileSystem("images"),
    
  ],
    
});

    Although the samples use the local filesystem, Ill be using cvs:dropbox, so you can’t rely on the file being there locally.
