I've moved your question to the InDesign forum.
The setup for placing Flash files from a URL into InDesign is not well documented. All I can offer is what I wrote in an article in InDesign Magazine three years ago:
"To set up your document for streaming
video, start by creating an empty frame or
select a video you want to replace. Choose
Video from URL from the Media panel menu.
Specify the URL and click OK.
"Note that the URL must point to a file that
ends in the appropriate file extension; for
Intro_Video.f4v for a file on a web server. Use
rtmp:// in the URL for a video on the Flash
Media Server or Flash Streaming Service."
Thanks! I have done exactly that. If the file is local, it plays fine, but if I select a URL for a file that I know is F4V and http based, I get the basic ‘go away you are not Flash compatible nor do you have the correct extension’ message.
There must be a trick I am missing somewhere? ?? That same file when added locally, runs fine…
When I wrote the article, I could find no documentation anywhere about exactly how to set it up, I'm afraid. Maybe someone more familiar with server setup can help. I have a feeling it has to do with that.
