To get QTSS to re-read its preferences:

3Finally, restart Streaming Server Admin by entering the following:

streamingadminserver.pl

How do I get QTSS to re-read its preferences without killing or restarting the server?

One way to do this is to use Streaming Server Admin. Using your web browser, go to http:// qtss.domain.com:1220, for example, and stop and start the streaming server via the web interface. If you use this method, currently connected users will be disconnected.

Alternatively, you can send the child process of QuickTimeStreamingServer an HUP (-1) signal. Currently connected users will not be disconnected, but this method is a little trickier.

You must be logged in as root to perform this task.

To get QTSS to re-read its preferences:

1Open the Terminal application in the Finder and enter the following:

ps -ax grep QuickTimeStreamingServer

Text similar to the following should appear:

949	??	Ss	0:00.00 /usr/sbin/QuickTimeStreamingServer
950	??	S	0:00.13 /usr/sbin/QuickTimeStreamingServer
965	std	S+	0:00.00 grep QuickTimeStreamingServer

2Find the larger of the two process IDs (PIDs) for the QuickTimeStreamingServer processes. In this case, it is 950.

3To send an HUP signal to this child process, enter the following:

kill -HUP 950

How do I configure QTSS to host streams from multiple user media directories?

QuickTime Streaming Server can have one only main media directory. However, you can create symbolic links within this directory. This allows users to have read/write access to their own secure streaming media folders and to access the streams via RTSP (Real-Time Streaming Protocol) from a single QTSS media folder. Also, users do not need read/write access to the main QuickTime Streaming Server Movies directory (/Library/ QuickTimeStreaming/Movies/).

You need to be logged in as the administrator to create these links.

Here’s a simple way to conﬁgure the QTSS media directory so that multiple users (user1, user2, and user3, for example) have write access to their own independent movie directories:
