Os: Debian
Oh and it has to be stable ish.Yesterday I had to try and get php-ffmpeg and x264 enabled ffmpeg to sit side by side each other on a Debian Lenny install. The problem is that debian's ffmpeg that ships in the lenny package tree is not 264 enabled. But when you use the ffmpeg from
debian-multimedia it breaks the installed php-ffmpeg.
So I suggest you do this:
Start With vanilla debian install
Install your php, apache, php-ffmpeg etc
Then add your debian-multimedia.org as a apt source.
Then follow these instructions
