Does anyone have any experience of how to do this?
QuickTime video can be encoded to stream off of a video server, or
it can be encoded to stream off of any standard web server like
you're already using to host your current web site. This second
method of streaming is the most popular and is commonly referred
to as http streaming, or QuickTime progressive download (a.k.a
fast start).
Ideally I'd like to be able to play then without having to download
the movie first - and then have the data locally.
If you specify a URL for a streaming QuickTime movie file,
Revolution displays the movie sequentially as it downloads.
Otherwise, Revolution must download the entire file before you can
play it. To pre-fetch a file from the Internet in order to speed
up access to it, use the load command before visiting the card
that holds the player or image that references the file's URL.
OK - but in either case where is the downloaded QuickTime file and
how can I copy it to a permanent store?
David,
If I understand correctly, you can use the EnhancedQT external to
accomplish this. I do this in my apps by doing this:
1) If the movie does not already exist locally then set the filename
of the player to the http url.
2) QuickTime begins downloading the file progressively. This means
the video will playback while it downloads but you can't skip ahead
to a point that isn't downloaded yet like you could with a streaming
file.
3) When it comes time to unload the movie from the player you can
save it locally. First use qtGetMovieLoadState to make sure the
movie has downloaded entirely. If it has then use qtSaveAs to save
the movie file locally.
This works really well in that the user can start viewing the movie
instantly but you can still cache it for later viewing with no wait.
You can look at the enhancedQT external here: http://

You should use the 1.x version which is marked as beta but everything
works fine and it is the version I use in my projects.
