Using Shockwave Player
Macromedia Director MX movies can use the Internet in various ways: hosting multiuser sessions
such as chats and games, streaming movies and sounds, retrieving data from the network, and
interacting with a browser. Whether it is distributed on disk or downloaded from the Internet, a
movie can use an active network connection to retrieve linked files, send information, open web
pages, and perform many other network activities.
To make a movie appear in a user’s browser, you can save it as a Shockwave movie and embed it in
an HTML document. The movie can play from a local disk or an Internet server. When the user
opens the HTML document stored on an Internet server, the movie begins streaming to the user’s
system, and usually begins playing after the first frame’s content has been downloaded.
You can also distribute a movie over the Internet as a projector—a packaged movie that the user
downloads and executes. A projector plays in a stand-alone application, not in a browser. See
“About distribution formats” on page 574.
When you author a movie, consider how the movie will be distributed and played on users’
systems. If the movie will stream from an Internet source, you might need to modify the movie
for the best streaming performance and to use the behaviors that are built in to Director to make
the movie wait while certain cast members download. Controls and Lingo commands offer
methods for sending and retrieving media and other information, interacting with a browser, and
monitoring downloading.
About streaming movies
When you distribute a movie on the Internet, streaming provides an immediate and satisfying
experience for your users. If you do not specify streaming, your user must wait for the entire
movie to download before it begins to play. A streaming movie begins playing as soon as a
specified amount of content reaches the user’s system. As the movie plays, the remaining content
downloads in the background and appears when it is needed. Streaming can dramatically decrease
the perceived downloading time.
When Director streams a movie over the Internet, it first downloads the Score data and other
nonmedia information such as scripts and the size of each cast member’s bounding rectangle. This
data is usually quite small compared with the size of the movie’s media—usually only a few
kilobytes. Before starting the movie, Director then downloads the internal and linked cast
members that are required for the first frame of the movie (or more frames if you have increased
the number in the Movie Playback dialog box). After the movie starts, Director continues to
download cast members (along with any associated linked media) in the background, in the order
the cast members appear in the Score.
