It is simply a data format that is non-standard and that you have to pay for proprietary decoders. What is new about that? just because google give you that feature if you pay them with your data, does not make it free for everyone. so it is not in place for firefox.
Or should firefox charge a fee for each user? it is crazy, even so when the alternative is already existent and open standard.
what is even crazier is that they demand a payment, for a spec which only "benefit" over the open source code is that they can add DRM on top of it, so they can also charge the end user.
Arguably vimeo could make an effort here too, and do automatic transcoding and delivery to eg: webm and html5. It certainly wouldn't be trivial, but also not impossible.
Has anyone seen any recent news on why Google/youtube doesn't do this btw? The already do transcoding for different quality? And/or if they have any plans for a html5-based viewer that supports ads etc?
Almost nothing supports it. And with Apple dominating in web usage, editing tools and phones/tablets it is hard to see any format surviving without their support. And of course they are fully behind H.265.
if people had no voice youtube would still be showing quicktime or Real video.
I for one rather watch youtube (and uploads my videos there) because vimeo is a pain to watch (have to go get my closed source tablet). while youtube i can just hunt for a non-ad version that will work on html5.
