I think I seriously messed things up on my EC2 instance which I'm currently hacking on. I tried to install some rpmfusion repository from which to install FFMPEG, but it broke things and I wasn't able to do any updates or install anything.
So, I ran a pretty straightforward rm command: rm /etc/yum.repos.d/rpmfusion-*. I think this really messed things up, though, as I can't seem to find rpmbuild which I need to install FFMPEG.
Can anyone help me recover from this? I don't have access to the EC2 control panel, otherwise I'd just up another instance and start over. Can anyone instruct me on how to simply install FFMPEG on a CentOS-like OS?
