Simple helper script for AndroidUsbCamera startup

lsartory commented 14 years ago

Hello,

First, thank you for making this. I was looking for something like this for a while now. This isn't really an issue, but I couldn't find any other way to contribute.. I wrote a startup script to make it easier for me to launch AndroidUsbCamera, and I thought it would be nice to share it so I cleaned it up a bit.

It launches the application on the Android device, sets up port forwarding, attempts to auto-detect which video device to use, and finally starts AndroidUsbCamera.

You should only need to adjust line 71 to use the right path to launch AndroidUsbCamera, but I didn't test it extensively.

#!/bin/sh

echo "AndroidUsbCamera starter script"
echo "-------------------------------"
echo
if [ `adb devices | grep device | wc -l` -gt 1 ]
then
  echo -n "Setting up Android device.. "
  adb shell am start -n usbwebcam.application/.GWebcam &> /dev/null || (echo -e "\nAn error occured while starting the application"; exit 1)
  adb forward tcp:8080 tcp:8080 &> /dev/null || (echo -e "\nAn error occured while attempting to forward the port"; exit 1)
  echo "OK."

  echo -n "Checking module.. "
  if ! lsmod | grep vloopback &> /dev/null
  then
    echo -e "\nThe vloopback module is not loaded, loading it now.."
    if ! modprobe vloopback &> /dev/null
    then
      if which sudo &> /dev/null
      then
        echo "Loading failed, attempting with sudo.."
        echo "Please enter your password."
        sudo modprobe vloopback
      else
        echo "Loading failed, attempting with su.."
        echo "Please enter root password."
        su -c "modprobe vloopback"
      fi
    fi
    if ! lsmod | grep vloopback &> /dev/null
    then
      echo "The vloopback module is still not available, aborting."
      exit 1
    fi
  fi
  echo "OK."

  if [ -z "$1" ]
  then
    echo -n "Auto-detecting video devices to be used.. "
    DEVICES="`dmesg | grep vloopback | grep registered | tail -1`"
    INPUT=`echo $DEVICES | sed "s@.*input: \(.*\),.*@\1@"`
    OUTPUT=`echo $DEVICES | sed "s@.*output: \(.*\)@\1@"`
    if [ ! -e "/dev/$INPUT" -o ! -e "/dev/$OUTPUT" ]
    then
      echo -e "\nCouldn't find input or output device, aborting."
      echo "You can skip auto-detection by starting this script with the video input device as the first parameter"
      echo "e.g. $0 /dev/video0"
      exit 1
    fi
    echo "OK."
  else
    echo -n "Checking video devices.. "
    INPUT="$1"
    DEVNUM=`echo $INPUT | sed "s@[a-Z/]*@@"`
    OUTPUT=`echo $INPUT | sed "s@$DEVNUM\\$@$(expr $DEVNUM + 1)@"`
    if [ ! -e "$INPUT" -o ! -e "$OUTPUT" ]
    then
      echo -e "\nCouldn't find input or output device, aborting."
      echo "Please try with another device."
      exit 1
    fi
    echo "OK."
  fi

  echo -e "\nUsing $INPUT as loopback input. You should use $OUTPUT as webcam device in your application.\n"

  echo "Waiting for device to settle.."
  sleep 5
  echo -e "Starting AndroidUsbCamera..\n"
  ./AndroidUsbCamera $INPUT    # Edit me to properly start the application

else
  echo "No Android device was found, aborting."
  exit 1
