Raspberry Pi - Webserver installation Script

• Download the ZIP-file of this repository
• This installation script was used with an attached WebCam LogiTech C270 HD
• The settings for the WebCam server motion are defined in etc_motion_motion.conf. You can edit the file prior to running the script install_rasp_webcam_srv.sh and this file will be copied to /etc/motion/motion.conf
• The default settings are defined in etc_default_motion.conf and this file will be copied to /etc/default/motion

• Install git with sudo apt-get install git on your Raspberry Pi.
• Clone this repository by git clone https://github.com/niebert/raspi-webcam-srv.git
• Change to director cd raspi-webcam-srv
• You can install two different servers by calling one of the following installation scripts
  • motion: sh install_motion_srv.sh
  • ffserver: sh install_ffserver.sh - check default settings of the install script

You can start the WebCam server with start scripts:

• motion: sh start_motion_srv.sh
• ffserver: sh start_ffserver.sh You can also start the motion server manually by sudo motion -c /etc/motion/motion.conf

• USB WebCam
• USB Sound Device with Audio-In for broadcasting video and sound with an attached microphone to your Raspberry Pi. The sound for the video stream is recorded with USB sound device Please run alsamixer on your Raspberry Pi prior to the start of the webcam server. With alsamixer set the audio to USB PnP Sound Device, After this setting you can hear audio through the USB sound card.

The following video/audio broadcast uses the command line VLC cvlc. raspvid pipes the video stream into the command line VLC cvlc. This was added to the README.md as an alternative for motion as an updated stream of still images without audio. The following commands will help you to broadcast a video stream including audio. You will be able to stream

• video of the webcam and
• audio of a mircophone with the command line VLC to HTTP port. In constrast to motion the framerate will be much better. But this will also include a delay of 1-2 seconds. If you use the default Raspberry webcam, activate the camera with rasp-config. When the module can be activated, the Pi should be restarted afterwards.

Afterwards the Raspberry Pi should be updated to the latest version with the following commands:

    sudo apt-get update | apt-get upgrade

After the upgrade has been performed, you can install VLC with the following command:

  sudo apt-get install vlc

After VLC was installed, it is recommended to reboot the Raspberry Pi, before you can fully set up the video stream. Rebooting the Raspberry can be performed with sudo reboot from the console-

Afterwards the stream can be started easily from the console with the following command:

 /opt/vc/bin/raspivid -o - -t 0 -w 1280 -h 720 -fps 25 -b 1500000 -red 180 | cvlc -vvvv stream:///dev/stdin --sout '#standard{access=http,mux=ts,dst=:8090}' :demux=h264

Once the stream has started, all you need to do is open a new network stream in your client VLC player with

  http://{IP-DES-RASPBERRY-PIS}:8090

Please keep in mind that there is no password protection for viewing the video stream.

• All script are shell scripts that are interpreted with sh.
• The script can be made executable e.g. by sudo chmod u+x install_motion_srv.sh

The motion installation script basically copies the template file conf/ete_motion.tpl onto conf/etc_motion_motion.conf. Then variables like MOTION_VIDEO_FRAME_RATE in conf/etc_motion_motion.conf are replaced by defined values in the installation script. The replacement is performed with the stream editor sed. When all replacesments are performed sucessfully, then the file conf/etc_motion_motion.conf is copied to the final destination of the generated configuration file /etc/motion/motion.conf. The filenames in the subdirectory /conf with the extension conf are create according to the pathname where the generated file will stored. The conf/etc_default_motion.conf will be stored at /etc/default/motion.

The installation scripts are based on the recommendations of the following resources:
