Example PHP script for creating thumbnails

Tested with FFmpeg 4.0

Description

This is an example script that creates frame thumbnails from a video and generates a markup file.

It requires the FFmpeg and FFprobe libraries (you need to setup the paths to binary files if they are not installed). Other configured parameters:

• the width of the thumbnails (default is 160 px), the height is calculated automatically
• mosaic size (default 5x5)
• URL and name of the folder for images

To start you need to specify two variables - file (video) and output (markup, which will be generated in the end)

thumbnails.php?file=video.mp4&output=video.vtt

The script will create collections of images at the desired interval and generate a markup file in WebVTT format.
