Dave,

It's actually not clear to me why IceWeasel and Chromium can't use OpenH264
in exactly the same way that Firefox can, i.e., by doing download from Cisco's
site. I appreciate that people may have philosophical objections to doing
this, but I haven't actually heard any reason why this is a practical problem
as opposed to a philosophical one. This isn't to say that there aren't
situations
in which a downloaded module doesn't work, but I don't see that those are
any different for Chromium or IceWeasel then they are for Firefox.
(And

As a side note, the relationship between the Firefox binaries distributed by
Mozilla and the Firefox source isn't quite the same as between Chromium
and Chrome. The Firefox that is distributed by Mozilla is basically the same
as that you would get if you compiled the source yourself. By contrast, Chrome
contains a bunch of extra bits that are not in Chromium (e.g., Flash).
