52 Chapter 5 Troubleshooting and Technical Information

Administrator Can’t Use QTSS Publisher to Publish Media

Make sure your Mac OS X server has QTSS Publisher installed in the Server folder under

Applications.

• If you are unable to create a playlist or add to an existing one, make sure the owner

of the Media directory (specified in QuickTime Streaming in Server Admin) is “qtss”.

• Make sure the correct URL is being used (and has not been corrupted by user

modification).

• To set up your IP bindings in QTSS Publisher, republish all of your media. This step is

required if you change an address.

• Make a backup copy and delete /Library/Caches/com.apple.qtssserverpublisher.plist,

which is a cache of all the information about QuickTime content. It can be useful to

clear this cache (by deleting the file) if something goes wrong with QTSS Publisher

that you cannot fix through any other means.

Users Can’t Connect to Your Broadcast

Make sure the client computer has QuickTime 4 or later installed. If users are

connecting using a web browser, make sure the QuickTime 4 Plug-in is installed

correctly.

• Make sure users have the correct URL.

• If users are attempting to connect to your broadcast over HTTP, make sure you

disable any web server that may be conflicting with your streaming server. Also,

make sure streaming on port 80 is enabled in the General Settings pane of

Streaming Server Admin.

Users See Error Messages While Streaming Media

Here’s what the messages mean:

Error code 401: The user has tried to access a protected file. Users may need to upgrade

to QuickTime 5 or later.

Error code 404: The server cannot locate the URL the user entered. Make sure users

enter the correct URL for the broadcast. Tell users not to attempt to view media in a

web browser by typing an RTSP URL directly into the web browser’s location address.

RTSP URLs are used only with the Open URL command of QuickTime Player.

Error code 415: The movie file is not hinted or has a compressed movie resource. You

need to hint the movie again using the Pro version of QuickTime Player. Alternatively,

you may be attempting to natively serve MP3 files on demand (that is, as an HTTP

download). QTSS support of MP3 streams is intended for Shoutcast/Icecast-compatible

live streams (such as those created by an MP3 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.
