# Batch-generate .qtl ref movies, add hint tracks, add metadata,
# and move files to their final destination. 

# Usage: 
# Configure  base variables below.
# Place script somewhere in your path.
# cd to the dir containing raw movie files and type "makestreams"
# You'll be prompted for any needed input.
# This script must be run as root (QT requirement)


# CONFIGURE VARIABLES

# Repository location. This is the base path on the system where all 
# streamed media resides. This probably stays constant (you'll be 
# prompted to add subdirectories to this at runtime).

REPO="/Volumes/Media"

COPYRIGHT="The Regents, University of California, 2006"

# Base URL for streamed media at your site
BASEURL="rtsp://streams.journalism.berkeley.edu"

# Comment is a piece of metadata that can be a URL or any other string
COMMENT="http://journalism.berkeley.edu/events/video/"

# Since this script runs as root, the final output will be root owned.
# Since you might want to later manipulate the content through the Finder
# as a non-root user, we'll also set the user and group file ownership.
# Configure that  here.
