ipcam

Sample application for "V4L2 for Ruby".

Add this line to your application's Gemfile:

gem 'ipcam'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ipcam

Connect a camera device compatible with V4L2 and start ipcam as follows.

ipcam [options] [device-file]
options:
        --use-ssl
        --ssl-cert=CRT-FILE
        --ssl-key=KEY-FILE
    -D, --digest-auth=YAML-FILE
    -A, --add-user
        --bind=ADDR
        --port=PORT
    -d, --database-file=FILE
    -e, --extend-header
        --log-file=FILE
        --log-age=AGE
        --log-size=SIZE
        --log-level=LEVEL
        --develop-mode

Then connect to port 4567 by http browser and operate. The accessible URLs are as follows.

• http://${HOST}:4567/
  redicrect to /main
• http://${HOST}:4567/main
  preview and settings
• http://${HOST}:4567/stream
  http streaming

--use-ssl

Specify use SSL/TLS. If you use this option, shall specify a certificate file and a key file (Use the --ssl-cert and --ssl-key options).

--ssl-cert=CRT-FILE

Specifies the file that contains the X 509 server certificate.

--ssl-key=KEY-FILE

Specifies the key file that was used when the certificate was created.

-D, --digest-auth=YAML-FILE

Specifies to use restrict access by Digest Authentication. This argument is followed by a password file written in YAML.

-A, --add-user

Add entry to the password file. If this option is specified, the user name and password must be specified as arguments. And if you specify this option, only to add an entry to the password file to exit this application.
Overwrites the entry if you specify an existing user name.

--bind=ADDR

Specify the address to which the HTTP server binds. by default, IPv6 any address("::") is used.

--port=PORT

Specify the port number to which the HTTP server binds. by default 4567 is used.

-d, --database-file=FILE

Specify the file name to save the camera setting value. by default, it tries to save to "~/.ipcam.db".

-e, --extend-header

Add extend header to part data (for debug).

--log-file=FILE

--log-age=AGE

--log-level=LEVEL

To restrict access by digest authentication, the password file written in YAML must be specified in the "--digest-auth" option. This file must be YAML-encoded map data of A1 strings (ref. RFC 7616) keyed by the user name.

This file can be created using the "--add-user" option. The actual procedure is as follows.

If specified password file does not exist and the "--digest-auth" and "--add-user" options are specified together, new password file containing user entry will be created.

ipcam --digest-auth passwd.yml --add-user foo XXXXXXX

If specified password file exists and the "--digest-auth" option and "--add-user" option are specified together, a user entry is added to the password file.

ipcam --digest-auth passwd.yml --add-user bar YYYYYY

If only the "--digest-auth" option is specified, the server is started and performs digest authentication with the specified password file.

ipcam --digest-auth passwd.yml --use-ssl --ssl-cert cert/server.crt --ssl-key cert/server.key /dev/video0

To delete a user, edit the YAML file directly.

specify target device file (ex: /dev/video1). if omittedm, it will use "/dev/video0".
