It's rather frustrating to me that I can't watch any of the videos on Apple's site. Is there a QuickTime plugin for Chrome or Firefox, and if not, why?
Odd... Works for me!
I'm using the totem plugin which I thought shipped with Ubuntu. Have a look at
about:plugins in the browser and see if you can see "QuickTime Plug-in 7.something"
If you don't, check
totem-mozilla is installed. Might be worth installing the
ubuntu-restricted-extras package to make sure you've got the right codecs.
Just searching synaptic, I also have
libquicktime1 installed. It's a dependency of
quicktime-utils so it might be worth installing that. It might just be something used for encoding to quicktime.
Edit: you might also need
gstreamer-plugins-bad for AAC audio.
The Quicktime codec, like most other non-free formats, is provided as part of the
w32codecs package (or its 64-bit equivalent,
w64codecs) by Medibuntu. The community documentation includes instructions for installing.
Once the codecs are installed the standard media plugins for your browser should detect and handle them.
I've discovered that sometimes Apple actually detects which browser/OS you're using when it embeds videos on its site, and that can prevent QuickTime videos from playing even if you have the proper codecs and plugins installed. You can circumvent this in Firefox by changing your user agent string.
You'll need the User Agent Switcher extension:
And a user agent string that specifies a browser on Mac or Windows. There's a rather nice list of user agents here:
