Control of Video player

[Ron Zellner]

I have a scrollbar to control the speed that a movie plays at- but I don't want the movie to play when the scrollbar is changed; that currently happens with the script:

on scrollbarDrag newValue
divide newValue by 100
add .75 to newValue
put newValue into field "PlaySpeed"
set the playRate of player "MovieScreen" to newValue
end scrollbarDrag

If it is playing I want it to continue playing, if it is paused I want it to stay paused.

I assume that if I can determine the status of the player I can test for it.
I am currently trying to determine the status of the various attributes of the video player ("MovieScreen"). Where can I view that information?

This seems to do the trick:

Code: Select all

on scrollbarDrag newValue
   Put the paused of player "MovieScreen" into WhatIs -- Added this
   divide newValue by 100
   add .75 to newValue
   put newValue into field "PlaySpeed"
   set the playRate of player "MovieScreen" to newValue  
   
  if WhatIs = "true" then                      --Added this
      play pause videoClip "MovieScreen"
   else
      play videoClip "MovieScreen"
   end if
   
end scrollbarDrag

Hi Ron,

please don't mix players with "play videoclip"!
May cause unexspected results

See the docs for "play videoclip".

Use "start/stop player X" instead.

Code: Select all

...
  if WhatIs = "true" then                      --Added this 
      stop player "MovieScreen" 
   else 
      start player "MovieScreen" 
   end if 
...

Problem is that setting the playrate of a player object to any value but 0 will immediately start that player.


Best
