问题
I am following this http://www.phpclasses.org/package/3747-PHP-Manipulate-and-convert-videos-with-ffmpeg-program.html link to convert any video type to .mp4 i tried to run various example files but they are throwing error message. I can't get how to convert the file using phpvideotoolkit.
If i run the following file http://localhost/phpvideotoolkit-v2-master/examples/convert-to-multiple-outputs.php i get this error.
An error was encountered with FFmpeg when attempting to read the formats that FFmpeg supports. FFmpeg reported: The system cannot find the path specified.
