#1 on my list is... a natively supported video format common to all
Thus... like the way all (GUI) browsers support GIFs, JPEGs, and PNGs.
There should be at least one video format supported on all browsers.
I made this #1 because I think this is the most important thing on this
list. If I could only have one of these things on my list get implemented
it would be this one.
One of the biggest problems with video on the web (and probably video on the
Internet in general) right now is that there is no universally supported
(Note, this doesn't mean there can't be other video formats too. This only
suggests that there should be a baseline video format supported everywhere.)
On the Videoblogging Mailing List <
http://tech.groups.yahoo.com/group/videoblogging/>, the question about what
video format to support comes up over and over again.
And the answer that has to be given to them is that there isn't a single
video format... but essentially they have to encode to many many different
video formats, or else there will be people who can NOT view their show.
Often, people will only encode in one format. Not really by choice. Not
because they want to make it so certain people can't watch their show. But
because they lack the skills or tools to encode in the other formats.
Most of these publishers want everyone to be able to see their show though.
(A natively supported video format common to all browsers would solve this
Having said all that, I believe that whatever video format is choosen can
NOT be encumbered. By patents or anything else.
Such a thing is totally unacceptable.
Given this, I would suggest Ogg Theora be the natively supported video
format common to all browsers. It's designed from the beginning to be
unencumbed. And implementations for it already exist under licenses that
should make everyone happy.
There's also existing tool sets that support it. And existing developer
experience and knowledge about it.
If you don't mind hearing me get onto a soapbox and rant about this
particular topic, read this:
(Note... Dirac, Matroska, and NUT also exist. But neither of these are as
mature as Ogg Theora.)
