Chapter 4 Managing Your Media With QTSS Publisher 43

Connecting to Mac OS X Server

When you open QTSS Publisher, you must provide a user name and password for a

Mac OS X Server (version 10.4 or later) user account. Local users can log in if home

directory streaming has been enabled for them (see “Hosting Streams From Multiple

User Media Directories” on page 30).

If the attempt to log in fails, make sure that the server you’re trying to connect to is

running. Also make sure that port 311 is not disabled by your firewall.

Uploading Media From QTSS Publisher to a QuickTime

Streaming Server

Files you drag to the QTSS Publisher Library are automatically uploaded to the server

you’re connected to, but the media is not accessible to the public until you make it

available (see “Making Content Available for Streaming or Downloading” on page 48).

You can use QTSS Publisher as a staging area to prepare your content for web delivery.

Preparing Content for Web Delivery

After you upload your content to the server (by dragging files to the QTSS Publisher

window), and before you make your content available to the public, you may need to

prepare your files for delivery over the Internet. This section describes the process.

Preparing Prerecorded Media for Streaming

Before prerecorded media can play as a simulated live stream in a playlist, the media

needs to be prepared for streaming.

To prepare prerecorded media for broadcast in a playlist:

1 For movie playlists, make sure each movie has the same number and types of tracks,

and that all the media files contain compatible media types. For example, all audio

tracks should use the same encoding, sampling rate, compression, and bit rate. All

video tracks should also use the same encoding, compression, bit rate, and frame size.

For MP3 playlists, make sure all files use the same sampling rate.

2 Format the media in each file in the same way. For a movie playlist, be sure each media

file is a hinted QuickTime movie, a hinted MPEG-4 file, or a hinted 3GP file. (If you put

your files in the QTSS Publisher Library, they are hinted for you.) Do not hint MP3 files.

3 Open QTSS Publisher (in /Applications/Server) and click Library.

4 Drag media files from the Finder to the QTSS Publisher library list.

Important: QTSS 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. To serve an individual MP3 file on demand

(not as a live stream), select the file in the Library and then select “Publish MP3 file to

web server” (also called “Fast Start” in the User Access area of the QTSS Publisher

window).
