+
+# Script for using IP Webcam as a microphone/webcam in Debian Jessie,
+# Ubuntu 13.04, 14.04, 16.04 and Arch Linux
+
+# Copyright (C) 2011-2020 Antonio García Domínguez
+# Copyright (C) 2016 C.J. Adams-Collier
+# Copyright (C) 2016 Laptander
+# Licensed under GPLv3
+
+# Usage: ./prepare-videochat.sh [flip method]
+#
+# [flip method] is "none" by default. Here are some values you can try
+# out (from gst/videofilter/gstvideoflip.c):
+#
+# - clockwise: clockwise 90 degrees
+# - rotate-180: 180 degrees
+# - counterclockwise: counter-clockwise 90 degrees
+# - horizontal-flip: flip horizontally
+# - vertical-flip: flip vertically
+# - upper-left-diagonal: flip across upper-left/lower-right diagonal
+# - upper-right-diagonal: flip across upper-right/lower-left diagonal
+#
+# However, some of these flip methods do not seem to work. In
+# particular, those which change the picture size, such as clockwise
+# or counterclockwise. *-flip and rotate-180 do work, though.
+#
+# To be able to use audio from your phone as a virtual microphone, open pavucontrol,
+# then open Playback tab and choose 'IP Webcam' for gst-launch-1.0 playback Stream.
+# Then to use audio stream in Audacity, open it and press record button or click on
+# the Recording Meter Toolbar to start monitoring, then go to pavucontrol's Recording tab
+# and choose "Monitor of IP Webcam" for ALSA plug-in [audacity].
+#
+# If you want to be able to hear other applications sounds, for example from web-browser,
+# then while it is playing some sound, go to pavucontrol's Playback tab and choose your
+# default sound card for web-browser.
+
+#
+# INSTALLATION
+#
+# In Arch Linux
+# install ipwebcam-gst-git package from AUR
+#
+# MULTIPLE WEBCAMS
+#
+# This requires some extra work. First, you need to reload the
+# v4l2loopback module yourself and specify how many loopback devices
+# you want (default is 1). For instance, if you want 2:
+#
+#   sudo modprobe -r v4l2loopback
+#   sudo modprobe v4l2loopback exclusive_caps=1 devices=2
+#
+# Next, run two copies of this script with explicit WIFI_IP and DEVICE
+# settings (see CONFIGURATION):
+#
+#   ./prepare-videochat.sh
+#   ./prepare-videochat-copy.sh
+#
+# TROUBLESHOOTING
+#
+# 1. Does v4l2loopback work properly?
+#
+# Try running these commands. You'll first need to install mplayer and
+# ensure that your user can write to /dev/video*).
+#
+#  sudo modprobe -r v4l2loopback
+#  ls /dev/video*
+#  (Note down the devices available.)
+#  sudo modprobe v4l2loopback exclusive_caps=1
+#  ls /dev/video*
+#  (Note down the new devices: let X be the number of the first new device.)
+#  v4l2-ctl -D -d /dev/videoX
+#  gst-launch-1.0 videotestsrc ! v4l2sink device=/dev/videoX & mplayer -tv device=/dev/videoX tv://
+#
+#
+# You should be able to see the GStreamer test video source, which is
+# like a TV test card. Otherwise, there's an issue in your v4l2loopback
+# installation that you should address before using this script.
+#
+# 2. Does the video connection work properly?
+#
+# To make sure the video from IP Webcam works for you (except for
+# v4l2loopback and your video conference software), try this command
+# with a simplified pipeline (do not forget to replace $IP and $PORT
+# with your values):
+#
+# on Debian:
+#   gst-launch-1.0 souphttpsrc location="http://$IP:$PORT/videofeed" \
+#               do-timestamp=true is-live=true \
+#    ! multipartdemux ! jpegdec ! ffmpegcolorspace ! ximagesink
+#
+# on Arch Linux:
+#   gst-launch-1.0 souphttpsrc location="http://$IP:$PORT/videofeed" \
+#               do-timestamp=true is-live=true \
+#    ! multipartdemux ! jpegdec ! videoconvert ! ximagesink
+#
+# You should be able to see the picture from your webcam on a new window.
+# If that doesn't work, there's something wrong with your connection to
+# the phone.
+#
+# 3. Are you plugging several devices into your PC?
+#
+# By default, the script assumes you're only plugging one device into
+# your computer. If you're plugging in several Android devices to your
+# computer, you will first need to tell this script which one should
+# be used. Run 'adb devices' with only the desired device plugged in,
+# and note down the identifer.
+#
+# Then, uncomment the line that adds the -s flag to ADB_FLAGS below,
+# replacing 'deviceid' with the ID you just found, and run the script
+# normally.
+#
+# --
+#
+# Last tested with:
+# - souphttpsrc version 1.0.6
+# - v4l2sink version 1.0.6
+# - v4l2loopback version 0.7.0
+
+# Exit on first error
