Apostrophe issue with FFmpeg
1er mars 2024, par Rohan MolinilloI'm working on a company's project which is vue.js.
There are also code parts in php.
It uses FFmpeg to create a video from multiple videos.
On each video, there is a text type subtitle.
Each text is retrieved from a .txt file
But I have a problem with apostrophes.


If in the subtitle is stored like this ( I'm here ) in the txt file, on the video there will be written ( Im ).
The apostrophe is removed and the rest of the text too ( here ) will not be displayed.


I'm new to php and ffmpeg, I've been on this problem for almost 3 weeks.


I share the php code with you.


<?php

I tried many things but each time there were errors.
I think I didn't implement the code properly.
