# vids2web.sh
#  Script to run speech2text.sh on a video, then copy the results to
# the output folder /var/www/public/video (and /sub) so they appear in
# the video browser (run as an Apache2 service in the VM)
#
# for now only works for .mp4 video file format due to web video player

# Best practice: place videos in shared host folder /vagrant/www/video
# then run this script which will transcribe and produce subtitles and
# update video browser page
#
# Then view in Chrome browser on the IP found in Vagrantfile (nominally 192.168.33.11)
