ffmpeg with php exec disabled?

The Gallery2 script uses SYSTEM() & EXEC() to call FFMPEG

For security reasons both those PHP functions appear to have been disabled on my shared web hosting server.

Is there another method to use for executing FFMPEG?

Can you upload your own CGIs? If so, upload a bash script (named something.cgi) that starts ffmpeg and visit it.

Try making a file called "foo.cgi" with this content:

#!/bin/bash
echo "Content-type: text/plain"
echo ""
ls -Fal

Upload that to your web root, then go to http://yoursite/foo.cgi
