Bash Script to Add H.264 Support for Firefox

I’ve done it manually like described here: How-to: h264 etc. Support for Firefox (including ffmpeg install) and it is working for me.

What I’ve noticed are different directories to your script. Maybe that the point?

§ cat /etc/ld.so.conf
include /etc/ld.so.conf.d/*.conf
/usr/local/lib

$ cat firefox.conf 
export LD_LIBRARY_PATH=/usr/local/lib

FFMpeg Conf is here:
/etc/ld.so.conf.d/ffmpeg.conf
