Hello, Note that I said "when it is available". I'd strongly encourage Codec/Plugin developers to add support for it. As I know you'll have a certain class of web developers screaming for this feature. (And you'll be able to create alot of "cool" stuff with it :-) ) -- Charles Iliya Krempeaux, B.Sc. http://ChangeLog.ca/ On Tue, Oct 14, 2008 at 12:34 PM, WeBMartians <[EMAIL PROTECTED]> wrote: I agree that scrubbing requires non-1X audio. However, to require it is going to cause CoDec/PlugIn developers not just headaches but maybe aneurisms as well. Interestingly enough, audio at varied play rates has the potential to retain tonality. Since the audio is encoded with something like a Fourier transform, the data is "spectral" rather than "wave." The samples may be presented tonally-accurate even if their duration is not 1:1. Nonetheless, you're going to be very unpopular if the word "required" starts showing up. Best! ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Charles Iliya Krempeaux Sent: Tuesday, 2008 October 14 15:24 To: Ian Hickson Cc: [EMAIL PROTECTED] Subject: Re: [whatwg] Video : Slow motion, fast forward effects Hello Ian, On Mon, Oct 13, 2008 at 3:41 PM, Ian Hickson <[EMAIL PROTECTED]> wrote: [...] On Thu, 7 Aug 2008, Charles Iliya Krempeaux wrote: > > This feature would be used to implement "scrubing".

I agree that on the long term we would want to provide this, but I think that is something we should offer as a separate feature (e.g. a flag that decides whether reverse-playback audio is muted or not, defaulting to true for compatibility with today). If there's some way of turning this feature "on" (when it is available)... that would be sufficient for scrubbing AFAICT. -- Charles Iliya Krempeaux, B.Sc. http://ChangeLog.ca/
