Good morning,
after reading all mails in this thread I'd like to comment on this. I care about this topic as I am leading the WikiTV project we started in Germany (http://meta.wikimedia.org/wiki/WikiTV#WikiTV_.28on_demand.29).
I would appreciate to see WebM out soon, I think that is important. So here I agree with Michael - get the TMH released and then add H.264 support later.
What is unclear to me: Do you mean to store all video data in an intermediate format (be it Ogg or WebM or whatever) and then do a realtime encoding based on the browsers preference and capabilities?
From a usability point of view this would be perfect. I wouldn't be
happy if I needed to upload WikiTV shows in three different formats in the future and I think it would also wasting a lot of disk space. Let alone that these files need a developer to actually get imported into Commons from a FTP server we have to host on our end because we can't upload more than 100 MB, which are 80% of our files.
