• How to setup a video chunker or FFMPEG to bypass Cloudflare ?

  20 avril 2021, par RustyGates

  In full transparency, I am a noob so please forgive my lack of appropriate lingo as I am just barely starting to learn the languages of web development. Hope you don't have to try and decipher too much of what I'm trying to say.

  


  So in an attempt to put this as simply as possible.

  


  I have a PHP Script CMS that I have been doing some extensive custom work to. As mentioned, I am still learning for the most part and while my front end skills are getting very well polished, I'm still completely lose mostly when it comes to back end endeavors. And for reference, the CMS I am using is Wowonder from Codecanyon. It's essentially just a social media cms, like Facebook.

  


  I have this installed on my own dedicated server, have WHM/Cpanel, all that good stuff. I also have my website/domain setup through Cloudflare properly. This is where the issue arises. Cloudflare limits uploads to 100 megabytes. Some of the users on my website will be uploading videos and media much bigger than 100 megabytes. (Up to 10 gigabytes in some cases). I have researched the issue long and hard and it would seem to me the obvious was to resolve the problem would be to use a video chunker (and/or something like FFMPEG ? But not sure if FFMPEG Is capable of it. Am just assuming).

  


  I understand the basic, general idea of what chunkers do and have found some seemingly good options. Will post a couple below just as an example but not necessarily options I was considering.

  [https://github.com/c0decracker/video-splitter][2]

  


  [https://github.com/appijumbo/video-chunk][3]

  


  So again, I understand the basic idea, it would chunk up the video while uploading (somewhere beneath the 100 megabyte maximum) to bypass Cloudflare's limit, and then stitch the video back together so it's in it's in it's complete form again. However, with a website that has many users uploading, I have not the slightest idea what the best solution is, or if this is the best solution at all, and if it is, how to implement it properly.

  


  I have also installed FFMPEG on my server and did so successfully but not sure how to implement that properly either now how to tell it that it should automatically encode any videos uploaded to the website by any users and so on, nor sure if it's possible to do chunking with it although it seemingly is ?

  


  Any advice is on the topic is much appreciated and I would be much obliged. Thanks in advance.
