What is the best way to decode the video after uploading to the site?

Question

PHP

There is a site, ffmpeg, ffmpeg-php is installed on the server.
Users upload videos to the site (in various popular formats), and after any action, it is laid out for public viewing.
But as you know, quite a few formats are normally reproduced in the browser.
In this case, for example, let it be mp4.
Now I have written some kind of conversion that starts immediately after loading and naturally loads the processor.
But in the end it converts.
How can I run this process in the "background" so that the user downloads the video, he was told that it was successfully uploaded and let him wait.
Except the crown.
I apologize if the question is stupid, but I'm not strong in the video, and even more so in its conversion.

Answer 1

Why doesn't cron work for you? And why invent bicycles?
Once a minute, we check if there are new unconverted files, if there are, we add them to the queue..

Answer 2

Your best bet in such cases is to use a queue server such as RabbitMQ or Gearman.

Answer 3

These issues are resolved by the crown. everything alternative is just an alternative to the crown.
