Buongirono Benjamin,
hello!
I exported a PowerPoint presentation
of an educational slideshow which
I imported to Revolution but I can't
find the proper scripts to
Play the Quicktime frame by frame.
I want to create 3 buttons:
BTN1: Play next frame and stop
BTN2:Play previous frame and Stop
BTN3:Rewind quicktime to frame 1
Have anyone done that? any help?
I have not done this (yet) but you can use Trevor De Vores extermely
wonderful "Enhanced QuickTime External" to retrieve the necessary
informations to do what Peter T. Evenson kindly suggested :-)
Get it here:
http://www.bluemangolearning.com/developer/revolution/enhancedqt.php
Although it is 1.0.0 b8 it works very fine!
For 1. and 2. you can use:
qtGetMovieFileDuration( )
which returns something like this for a movie:
76800,600 = the number of frames in QT timescale, the QT timescale of
the movie
And:
qtgettrackframecount( ) = the number of frames in the movie
Then you can calculate the info about how much you will have to add/
subtract
to/from "the currentTime of player xyz" to step frame by frame.
3.
...
set the currentTime of player xyz to 0
## The first frame in a movie = 0
...
Hope that helps.
Thanks!
Ben
