# stream - Stream video when called from crontab
# Usage:  stream <tag>
#   The tag refers to video files in $repopath/uploadpage/streams without the
#   '.mp4', that should have been re-encoded by `encode`. The tag has no path
#   information, has the "streamkey" at the start before the dot (it has to have
#   a dot!) and the "target" at the very end, after the '@'.
