Hi,

I have been playing around with the WebAudio API, and I am unfortunately unable to manipulate the audio contents of a <video> tag. In Chrome I can do so without problems, but in Safari/WebKit nightly I can't.
The reason I want to use Safari/WebKit nightly is that the streams I wish to manipulate the audio of are HLS streams, and are currently unsupported in Chrome for various political reasons.

I am doing TV interface mockups, and want to experiment with 3D audio positioning on live streaming content.

The sample I have linked to above is not of my creation, but shows what the issue is all about.

createMediaElementSource is the API call I would expect working on <video> tags.

Unfortunately, we haven't yet implemented that part of the WebAudio API.  It's on our radar though.

any estimates?

Also note that createMediaElementSource works with the MediaStream API, which isn't fully implemented or enabled yet.
