Be sure to copy the files into the directory you specified for streaming.
Preparing Audio
MP3 audio files can be played back in an MP3 playlist and listened to using iTunes or another
compatible streaming MP3 player.
To prepare MP3 files:
1 Open the audio file using software that can convert it to MP3 format.
2 Save the audio files as MP3 files.
3 Make sure all audio uses the same encoding, sampling rate, compression, and bit rate.
4 Copy all prepared audio files to the media directory on your streaming server.
Streaming Media Files With Multiple Sources
QuickTime movies often use content from several media files. For example, a video clip can
be combined with music stored separately from the video. When you export a QuickTime
movie, make it a “self-contained” file so that it includes all the source media. This improves
server performance.
If, for some reason, you cannot export the movie as self-contained, here’s what you can do.
To stream movies that are not self-contained:
1 Copy all the files needed by the movie to the same folder or directory.
2 Store all the files in the directory on your server that you specified as the media directory in
Streaming Server Admin.
Streaming File Formats Like .avi, .text, and .wav
If you have QuickTime Pro (a set of advanced features available with QuickTime Player), you
can apply hinting to .avi, .text, .wav, and other file formats. Hinting allows you to stream a
non-.mov file using QTSS or DSS while retaining the original file.
To hint a file, you must import it into QuickTime Player and then export it as a hinted movie.
Important QuickTime Streaming Server (QTSS) or Darwin Streaming Server (DSS) cannot
be used to natively serve MP3 files on demand (that is, as an HTTP download).
Rather QTSS and DSS support of MP3 streams is intended for shoutcast/icecast-compatible
live streams (such as those created by a streaming playlist) or live streams of other
compatible MP3 live encoder broadcasters.
If you wish to serve individual MP3 files on demand (not as live streams), simply host the files
on a web server in a web documents folder.
