Hi Mick, Thanks for the feedback ... very helpful.

I'm pretty sure soundOfSpace does it correctly (for both).

It was logged many years ago ... Quicktime has the capacity to stream AC3 directly to the hardware decoder *except* when it is embedded in the browser. Apple says this is not a bug. Its possible to get it working through a plugin called Perian, but then the entire file needs to be downloaded ... so it's not exactly streaming. The Perian people have told me this just needs to be developed and said open-source was all about people contributing their own code. I've been meaning to remove that option for a while because it is mostly useless. (which is why I thought I'd see what HTML5 can do first). > Using VLC is easily the best because it has its own encoded stereo option > which saves changing > overall options and I can it triggers the yamaha recieving it.

I think what is needed is a table that identifies which 5.1 format for which browser for which OS for which stereo decode is best. Then I'll implement that (and others can implement that) .... and so people could say "works with Chrome 10.1 + on windows, or .... " etc. Etienne -------------- next part -------------- An HTML attachment was scrubbed...
