# Suppress video

#VideoQMax 31
# Set this to the number of seconds backwards in time to start. Note that
# most players will buffer 5-10 seconds of video, and also you need to
allow
# for a keyframe to appear in the data stream.

# ACL:
# You can allow ranges of addresses (or single addresses)
#ACL ALLOW <first address>
# You can deny ranges of addresses (or single addresses)
#ACL DENY <first address>
# You can repeat the ACL allow/deny as often as you like. It is on a per
# stream basis. The first match defines the action. If there are no
matches,
# then the default is the inverse of the last ACL statement.
#
# Thus 'ACL allow localhost' only allows access from localhost.
# 'ACL deny 1.0.0.0 1.255.255.255' would deny the whole of network 1 and
# allow everybody else.
