I'm looking for a plugin that would allow me to synchronize a set of images with a video. I can do this today with the Javascript API and some DOM manipulation. Maybe even linking an ImageRotator with an FLVPlayer via Javascript would be OK. But it seems like a plugin implementation in Flash might be a more solid alternative.

I've considered writing one, but I see in the JW Player Roadmap (item #326) that someone's already done this. I don't see it on the longtailvideo site anywhere. Is this plugin, or one like it, available?

Thanks,
Larry

Hi Larry

I'm also looking for the same. Want to play a PPT sync and manipulated by video on JW Player. Want to make it as a plugin for JW Player. Also allow users to upload new ppt and mark sync points while they are watching the video.

thnx

There's no way to play a Powerpoint file in Flash

Yes but can you synchronize the 2 different applications and view them in some type of combo player.

Use Cue Points. No plugins needed.

i know using cue points we can sync images to the video..
but imagine the user is uploading a video (of any format) and a PPT with 10 slides, what can we make out of it?

lets put the PPT and video in separate frames, then too how to sync them?
But its amazing, that VCASMO.com have done this with perfection!!!!

It's really pretty simple:

1) user uploads video file, ppt file, simple list of slide-number/time.

2) simple PHP script extracts slides (if you are going to be doing a lot of these, stash them in a database)
option: extract slides on-the-fly as requested by your code from the Cue Points,

3) simple PHP script creates and injects the XMP object with the cue Points,

4) user plays video, as the cue Points are hit, the slides are requested from the server and displayed wherever/however you want.

PHP code to extract PPT slides:
<?php

$app = new COM("PowerPoint.application") or die("Unable to instantiate PowerPoint");
$app->Visible = true;
$pres = $app->Presentations->Open("D:/nginx/html/Water Conservation Project.ppt") or die ("Could not open presentation");
$app->Presentations[1]->SaveAs("D:/nginx/html",18);
$app->Presentations[1]->Close();
$app->Quit();
$app = null;

?>


I also have the PHP code to create and inject the XMP object into the FLV container or into the F4V container with H.264 video if anyone is interested in developing this application further.
