When I searched for this error, it seems to be more common in CentOS but I'm using Ubuntu 15.10.
My issue is that I've followed this installation on ffmpeg-php's site and I've ran into an error when doing this command.
./configure && make

How do I fix this? Some people said to just do
sudo apt-get install ffmpeg-dev`` orffmpeg-devel` but neither have worked and it's getting frusterating that there's no solution for this right now. It's like I'm the only one having this issue.
And yes my FFMPEG is installed, if I type in ffmpeg -cmd then I receive data from ffmpeg. And I am able to encode a video so it IS installed.
