This port is now prepared for html5 video via the gstreamer framework.
Two new ports have been added as dependencies:
gstreamer
gst-plugins-base
For full support you will also need to install gst-plugins-good and
gst-libav. These ports can be added at a later date without having to
rebuild gstreamer or firefox. See the README for more (the same) info
and feel free to contact me with any issues.
