Subject: Re: Suggestions on audio with PPT slides
There are a variety of ways to do what you want using RealPlayer. The easiest
would be to use RealPresenter to create the entire presentation directly from
Powerpoint. For more control over the process, you could also export the
Powerpoint as HTML, and then use the GIFs or JPGs that Powerpoint creates in
that process to create your own SMIL/RealPix presentation that synchronizes the
slides with the (single) audio file. (for more on SMIL and RealPix, look at the
WebTechniques article and code example linked from my site at
http://www.people.hbs.edu/lbouthillier/smil/ and at the SMIL documentation at
Real's site).
To create an index of links into the presentation, you can do one of two
things. 1) Simply create links in a web page that point to .ram files that use
the start=hh:mm:ss parameter. These links could be simple text or thumbnails
of the slides themselves. The start time in the .ram file will cause the
player to jump to that point in the presentation. 2) If the RealPlayer is
embedded in the web page, you can use javascript and the setPosition() method
of the RealPlayer plugin to cause the presentation to seek ahead (or back) to
that point in the presentation.
Hope this helps.
