Hi,

in my embedding (from codebase of FF 3.6.7), when I try to view a WebM
video on YouTube (after having turned on the beta option, obviously),
the browser stops on the initial black screen with the revolving wheel
and the HTML5 logo. I tried with several WebM videos correctly working
with a regular Firefox, always getting this behavior.

Which interfaces must be implemented to get it working? I hoped it
would have worked out-of-the-box, but this does not seem the
case... :)

Thanks!
Aaron/Babele

A few preference settings need to be provided beforehand.

Also, you need to grab the control bar images and associated javascript
files from the equivalent Firefox build

3.6.x is based on Gecko 1.9.2.x, which doesn't have webm support.

A regular 1.9.2-based firefox?

Ha. I did it again. I was playing with FF4 beta 1 and WebM was
working, but my embedding was crashing. So I reverted my embedding to
a FF 3.6.7 codebase, and I did not realize that the "several WebM
videos correctly working" are correctly working with a Firefox using
the FLASH PLAYER, which for some reason gets called even on HTML5/WebM
videos... shame on me. In fact, this video:

http://www.youtube.com/watch?v=rLxQiI8c1Bs&feature=related

does not fall back to flash player when loaded, and it does not work
with FF 3.6.7, even with flash player installed... but it works with a
FF 4 beta without any video plugin (GREAT!!).

So: will HTML5/WebM videos work out-of-the-box in my embedding (when
using Gecko 2)? :)

Thanks!

Unless something really weird happens, I'd think so!

thx, Steve. In fact my build of FF4B1 is working fine with HTML5/WebM
videos, but my embedding is not (it does not progress in the load, it
seems...), and I suspect I am missing some prefs and defaults in my
application... could you please provide some link to pertaining docs?

thx again,
Aaron
