Re: Some notes on multimedia support in iceweasel

Sure, it is relevant.  I've so far done trivial testing, by doing
'aptitude install plugin', and then starting firefox to do the
testing.  I have not checked which configuration and support packages
were in effect.  I expect the plugin package to take care of that.

Sound like support hell. :/

Make me even more happy with the mplayer plugin as the default plugin
in Debian Edu/Lenny. :)

I welcome help with the testing.  I doubt I will find time to spend
enough time with each plugin to figure out which configuration is
relevant to document.  :)

I am not sure which setting was used with the totem-mozilla package.
I suspect xine, but it might have been gstreamer.

Note that the script do not care about the backend used.  It only
report the MIME types claimed to be supported by the plugins, and this
do not change depending on the backend (which is rather strange, as
the backends probably do not support the same set of format. :).

Yeah.  The order of installation will affect this, and I do not know
what was installed in which order when doing the testing.  I just did
'aptitude remove oldplugin; aptitude install newplugin', or sometimes
'aptitude install plugin1 plugin2 plugin3 ...' (when extracting the
list of supported MIME types).

Happy hacking,
