• Can I stream 2 AVI or MP4 files to a user as if it were 1 file?

  12 March 2015, by Macmee

  I have several video files such as:

  bobs_video_part_1.mp4
  
  bobs_video_part_2.mp4
  
  bobs_video_part_3.mp4

  and instead of sending the user links to download each video separately:

  http://mynodejsserver.com/videos/bobs_video_part_1.mp4
  
  http://mynodejsserver.com/videos/bobs_video_part_2.mp4
  
  http://mynodejsserver.com/videos/bobs_video_part_3.mp4

  I want to be able to give the user just 1 link:

  http://mynodejsserver.com/videos/bobs_video.mp4

  I can combine the videos using something like ffmpeg but then I can’t give the user a link to the video in real time, I have to wait for ffmpeg to finish. I was thinking conceptually that this would work by doing something along the lines of:

  1. open file streams for each video and sum them to calculate total content-length
  
  2. open a stream/pipe back to the user and start sending data for bobs_video_part_1.mp4
  
  3. in that same stream start sending back bobs_video_part_2.mp4
  
  4. keep sending back the next video to the same stream/pipe to the user

  would something like this work? Since I want to send each video in order anyway I don’t see why I can’t send each video as if it were part of the same video and the client doing the download request would never know.

• "Uncurve" Cinerama-like videos

  2 August 2021, by silent

  I'm pretty new to ffmpeg and I recently found interesting videos that are trying to simulate the Cinerama technology back from 1950x by curving the final video.

  


  Here is the screenshot how it looks like during the playback:

  


  I was wondering if it's possible to make this kind of picture back to "normal" rectangular shape?
Here's a small (30 seconds, 48MB) example of how it looks like: https://ufile.io/8b0139j0

  


  Thanks!

  Discreet Cleaner 5
  Capture, author, encode, and publish multimedia in Real, QuickTime, Windows Media, MP3, DV, and MPEG formats. This package has a copyright date of 2001 (thus predating Flash video by a few years). This software seems to have since been purchased by Autodesk and is up to version 6.5 (which does support Flash video).

  
  
  

  Discreet Plasma
  "Web 3D Design." Package is copyright 2002. Like the last package, this package also makes reference to Discreet being a division of Autodesk. Sure enough, Autodesk purchased them in 1999 and would later rename them Autodesk Media and Entertainment.

  
  
  

  Debabelizer
  "The Graphics Processing Toolbox." Looking down its list of features on the box copy, I honestly wonder if it can accomplish anything that ImageMagick can’t.

  
  
  

  MatchWare Mediator 7
  "Create Flash, HTML & CD-Rom Presentations." Wow, version 7, and with a latest copyright date of 2002 on the box. There’s still a top-Google-hit web page for MatchWare Mediator 9, this one instead emphasizing interactive CDs, HTML, and then Flash.

  
  
  

  Final Cut Pro v1.2.5
  Promotional copy Apple’s video editing software. No copyright date, but it requires a PowerPC G3 or G4 and Mac OS 9.

  
  
  

  Apple Keynote
  More Apple software that I think can technically be classified as multimedia-related. I’m not sure which version this is.
