How to make a queue in php with mysql

Question

oh

in my script, I run the exec () function to make a movie file with ffmpeg.

the problem is that ffmpeg can only work once on the server,

if 2 people are online on the server and the first one is already running ffmpeg, I want the second to wait for the first end of the process

how to encode it?

Thank you

You can use an asynchronous queue. Each new request is added to the queue as a message. Your process reads one message at a time and processes the conversion request.

For the PHP queue, you can try Dropr or similar.
