Managing Your Streaming Server 29
To apply hinting and export a file as a movie:
1 Import the file into QuickTime Player by choosing Import from the File menu.
2 Export the file by choosing Export from the File menu.
3 In the “Save exported file as” dialog, choose “Movie to QuickTime Movie” from the Export
pop-up menu, if it’s not already selected, then click the Options button.
4 In the Movie Settings dialog, choose Hinted Streaming from the pop-up menu and click the
Settings button.
Make sure that Make Movie Self-Contained is unchecked.
5 Close each dialog by clicking OK, choose a filename and location, and save the file.
6 Place both the .mov file (containing only the hint tracks) and the original file (containing
only the media data) on your streaming server.
If you have folders inside your media folder, make sure that both files are in the same folder.
For example:
New file with only hint tracks: myfile.mov
Original, non-hinted file: myfile.avi
To stream the original file, use an RTSP (Real-Time Streaming Protocol) URL that references
the hinted “.mov” file.
7 In QuickTime Player, choose “Open URL in New Player” from the File menu, then enter the
following URL:
rtsp://qtss.hostname/myfile.mov
The file should begin streaming. The RTSP URL from the client tells the server to read the
hinted file and directly stream the media data from the .avi file.
Exporting a QuickTime Movie as a Hinted Movie
Hint tracks contain information the streaming server needs to stream the media properly.
Hint tracks allow the streaming server to stream QuickTime movies without having to
understand QuickTime media types or codecs. The server only needs to know the hint track
format. When a new codec must be streamed, typically the server software doesn’t require an
update. Hinting also precomputes packetization rules for some media that normally require
bit-level parsing, interleaving, and so on, relieving the server of this task.
Most authoring applications let you export media as a hinted QuickTime movie. If you have
QuickTime Pro, you can also hint a movie using QuickTime Player. QuickTime Pro is available
for both Mac OS and Windows computers. Check the QuickTime web site for more
information.
