Sur la question de l'ouverture peut être insuffisante de WebM dans son développement; des solutions ont été discutées récemment : lire "WebM: Testing, Metrics and New features" http://blog.gingertech.net/2011/10/... :

"This session was moderated by John Luther and John Koleszar, both of the WebM Project. They started off with a presentation on current work on WebM, which includes quality testing and improvements, and encoder speed improvement. Then they moved on to questions about how to involve the community more.

The community criticised that communication of what is happening around WebM is very scarce. More sharing of information was requested, including a move to using open Google+ hangouts instead of Google internal video conferences. More use of the public bug tracker can also help include the community better.

Another pain point of the community was that code is introduced and removed without much feedback. It was requested to introduce a peer review process. Also it was requested that example code snippets are published when new features are announced so others can replicate the claims.

This all indicates to me that the WebM project is increasingly more open, but that there is still a lot to learn."
