This guide is written with bash comments, so the whole text block below can be copied and pasted into an install.sh file if you’d rather not go through step by step. I wouldn’t recommend it though, as something could always go wrong, and it could be challenging hunting down the problem in that massive wall of output lines!

Wow! That was long…glad that’s over. Anyway, you should check and make sure it worked by running phpinfo() in php and searching for a block called ‘ffmpeg’. If anyone has any suggestions for improvements to the script or other encoders I should add let me know.
