I'm currently working on a PHP project where I need to convert a WAV audio file to MP3 format using the ffmpeg library. I have the WAV file stored in a PHP variable, and I'm wondering if it's possible to convert it directly to MP3 without saving it as a separate file.
I've been searching online for a solution, but I couldn't find clear instructions on how to achieve this particular task. I saw some examples of using ffmpeg in PHP, but most of them were based on converting a file from a specific path, rather than from a variable.
I would greatly appreciate it if someone could guide me on how to perform this conversion using the ffmpeg library in PHP, specifically when the audio file is already stored in a PHP variable. Any code snippets or suggestions would be highly beneficial.
Thank you in advance for your help!
