Topic: How to install ffmpeg PHP extension

[Kreten8]

From here https://www.apachelounge.com/viewtopic.php?t=6359 I downloaded PHP 8.3.14 binaries, which contains the PHP extension php_ffmpeg.dll. I added it to the extensions section in php.ini. However, this is not enough for it to work, because it does not appear in phpinfo and after starting Apache, an error is written to the php log:

When I look inside php_ffmpeg.dll, there is a link to avutil-56.dll, which is not part of the distribution. And when I tried to find it on the Internet, the message "The specified module was not found" changed to "The specified procedure was not found". So this library is missing, but the one I downloaded is not the right one, so I need the one that was part of the project when compiling PHP.

So I managed to install the ffmpeg extension in php 7.3.33, where the avutil library is bundled, but I lack any documentation for this extension. I am not able to write even a single line of correct code. What I need is to find out the total length of the mp3 file.
