I went to begin watching online Lynda.com training on my third monitor. You may remember I use Synergy to control the screen as I use an entirely separate computer to drive it. That computer was recently updated to Fedora 15. When I went to watch the video, using the Advanced QuickTime format which allows me to control the speed, one of the many things Lynda.com does right, I get the message: Need to download an MPEG-4 AAC decoder, and H.264 decoder. I clicked on the Fedora Search button and it informed me that I already had them installed.
A quick Google search made me remember that I hadn’t installed VLC yet. Which means it was time to install the rpmfusion repository rpmfusion.free.release.stable.noarch.rpm. Installing VLC also installs the Gstreamer codecs and now the video displays quite nicely.
