It May Be A While For WebM In Adobe's Flash
Phoronix: It May Be A While For WebM In Adobe's Flash
While Adobe previously said it would support Google's WebM video format within their Flash Player software, it doesn't look like this support will be arriving soon...
I always thought Adobe was being stupid to add WebM support
It was only going to encourage people to stop using Flash.
If Flash supports WebM, then it's a viable codec by itself, and websites could serve all their video in that format. That would just encourage websites to look at HTML5 video instead of going through flash.
By leaving support out, websites would have to create videos in both h.264 and WebM to make sure all browsers can view them, which is a much larger barrier to cross.
