Be sure to copy the ﬁles into the directory you speciﬁed for streaming.

Be sure to copy the ﬁles into the directory you speciﬁed for streaming.

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.

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:

1Open the audio ﬁle using software that can convert it to MP3 format.

2Save the audio ﬁles as MP3 ﬁles.

3Make sure all audio uses the same encoding, sampling rate, compression, and bit rate.

4Copy 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:

1Copy all the ﬁles needed by the movie to the same folder or directory.

2Store 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.
