Send command to build video in ffmpeg from website?

Question

linux

There is a site where a person can choose two videos from the list and combine them into one. A file is created with the paths to the video, and then you need to run the command, suppose: ffmpeg -f concat -i video -c copy
final.mpeg and automatically execute the script?

Answer 1

In my opinion, you can execute ffmpeg with the exec command, this command launches a third-party program (in your case, ffmpeg)

Answer 2

Post in php script and
php.net/manual/ru/function.shell-exec.php
not?

Answer 3

It is not worth launching from the site, because the browser will wait for the script to complete and the request will fail with a 504 error
. I implemented it like this:
1) web adds information about the task to the database.
2) a separate script in the eternal while (true) {
sleep (check interval);
checks whether there are tasks in the database and executes them.
after execution adds information about the readiness or problems with the video in the database.
}
to run third-party programs, take functions from here
, I also collected all the logs using the output redirection operators >>,1>> ,2>>
to control the output files, I monitored the fallen off workers
