Logging and Viewing Error Messages:A log of error messages can help you troubleshoot problems with streaming services. To log errors, open Quick Time Streaming Server Administration and be sure the Log Errors box in the Settings panel has a checkmark in it. (It is checked by default.) To view the error log file, choose Show Error Log from the Server menu.
If you click the Clear button in the Error Log window, information in the error log is copied to another file, named by date. If you don't clear the log, then error information older than one week is cleared automatically. If you want to delete the cleared access information, drag the dated file to the Trash.
Troubleshooting:
You will be able to troubleshoot streaming problems more easily if error logging is turned on. See the previous section, "Logging and Viewing Error Messages."
If performance seems slow:
If you are using the computer for streaming as well as other services, you may need to limit the number of connections or the throughput available for streaming so that other services do not slow down. If you do not want to reduce the number of streaming connections or the throughput, you may need to move other services to another computer.
1. If you are using 10-BaseT Ethernet, you may need to upgrade to 100-BaseT Ethernet.
2. Put media files on two or more hard disks. But because you can use only one folder for streaming, you need to create symbolic links from the streamed media folder to the actual location of each media file. For more information see the previous section "Making Multimedia Available for Streaming."
3. You may need to expand your server by adding additional hard disks, random-access memory, or Ethernet ports.

If streaming service quits unexpectedly:
1. Check the error log file for error messages.
If multimedia files are not streamed properly, or errors occur during streaming:
1. Check the error log file for error messages.
2. Check to be sure you have enough random-access memory to support the number of connections or throughput you've set up for streaming.
3. Check to be sure you are not running out of hard-disk space.

Preparing Media for Streaming:
Any "hinted" QuickTime file can be streamed. You use an application such as MoviePlayer Pro to export media as a hinted QuickTime movie.
A hint track contains information about the media file that's needed to stream the file properly. You must use an RTP hint track with QuickTime Streaming Server; other protocols will not work. Each track in a media file must have its own hint track.
Files do not need to be self-contained. If files are not self-contained, the files that they reference must also be placed directly on the server (AppleShare aliases will not work). In addition, files must have been prepared from the same volume, and placed on the same volume. (The file name in the hinted movie must be relative to the movie, not an absolute path onto another volume.) Enclosed files can be in "foreign" formats.
Reflecting a Multicast:
To reflect a multicast, copy the Session Description Protocol (SDP) file that describes the multicast to the streaming media folder you set up previously. You must use RTSP to reflect a multicast; other protocols will not work with QuickTime Streaming Server.
When you give your users the URL for the multicast, do not include the sdp extension. For example, if the sdp file is named "greatshow.sdp," the URL you give to your users is: "rstp://yourserver.yourdomain.com/greatshow"
Note: When you export a hinted streaming movie using MoviePlayer, you have an option to create an SDP file. This SDP file is unrelated to the SDP file needed to reflect a multicast. Do not make this type of SDP file and place it in the server directory. It will not work.
