What kind of output are you looking for? Interactive PDF? SWF? or Digital Publishing Suite? The answers may differ.
The display of a video, by the way, cannot be controlled in InDesign other than the controls on the Media panel. You only have two choices—an embedded video or a floating window.
This is not InDesign's ability to change. It's controlled by what can be done within the PDF specification, and what Acrobat/Reader has chosen to implement. Sorry for the bad news.
You can do that with SWF hack... but it works only when viewed with computer´s Adobe Reader or Acrobat, it does not work with Mac preview, Firefox PDF viewer, iOS or Android viewers etc... so I don´t know how usable this method is in real life...
Here´s my quick sample
Download PDF to your harddrive and open into Adobe Reader or Acrobat (has to be quite new version, maybe 7/8 or newer)
Video is on page 3... just click it... close popup by clicking outside of video...
Anyway, if you know that your document will be used with Adobe Reader and want to use that method, this is how it goes:
1) First you create a new document, same size as you spread in your original document
2) then you create 2 views; first one is a default view - what user sees when he enters the page... second view is a popup/lightbox view.
3) Group both views and convert them to a multistate object
4) Create opening button on the top of default view, and closing button inside popup/lightbox state, in my sample I created a transparent rectangle that covers whole page and converted it to close button. Use Go to next state action for both buttons
5) Export as SFW, 100% size, no HTML needed
6) Place SWF to your main document, put it behind other objects on the page.
7) Export your main document as interactive PDF
8) Open PDF in Acrobat, doubleclick SWF with video tool, check transparent background
9) Go to Resources tab, import Resources folder InDesign created same place with SWF when you exported it (actual video file is there and it has to be embedded into PDF)
You can customize both views as you wish, by using InDesign´s tools.... you can also create a X-button for closing if you like...
Nor would it work on any mobile devices. Nor would it work if Flash was not installed.
I think Adobe Reader 9 and 10 includes their own separate Flash Player but yeah... I can read between the lines and I agree with you... flash is unfortunately coming to end of it´s path...=(
Adobe should add support for HTML/HTML5 widgets to Acrobat/Adobe Reader... or it would be even better if ISO added that support into PDF specification.
It´s quite obvious that people want to add interactive stuff to their interactive PDF files and if Flash/SWF is not reasonable format for doing that, there should be another option.... just my 50c...=)
I totally agree with you Petteri!
