=head1 NAME
zmstreamer - eyeZM video streamer
=head1 SYNOPSIS
zmstreamer -e <mode>
zmstreamer -o <format>
zmstreamer -u <buffer size>
zmstreamer -f <maximum fps>
zmstreamer -s <scale>
zmstreamer -b <bitrate in bps>
zmstreamer -m <monitor id>
zmstreamer -d <debug mode>
zmstreamer -i
zmstreamer -?
zmstreamer -h
zmstreamer -v
=head1 DESCRIPTION
*DEPRECIATED* The xml skin and all files associated with the xml skin are now
depreciated. Please use the ZoneMinder API instead.
This binary works in conjunction with the XML skin to stream video to iPhones
running the eyeZm app.
=head1 OPTIONS
-e <mode> - Specify output mode: mpeg/jpg/zip/single/raw.
-o <format> - Specify output format.
-u <buffer size> - Specify buffer size in ms.
-f <maximum fps> - Specify maximum framerate.
-s <scale> - Specify scale.
-b <bitrate in bps> - Specify bitrate.
-m <monitor id> - Specify monitor id.
-d <debug mode> - 0 = off, 1 = no streaming, 2 = with streaming.
-i, -?, -h - Display usage information
-v - Print the installed version of ZoneMinder
