Configuration files

This syntax is updated to v1.12. Previous versions won't accept it.

There are four configuration files that will be loaded if found:

  • /etc/vcs.conf: System-wide configuration
  • ~/.vcs.conf: User configuration 1)
  • ~/.vcs/vcs.conf: Newer alternative to ~/.vcs.conf)
  • ./vcs.conf: (i.e. vcs.conf in the current directory) Per-dir configuration

See also profiles for an alternative to auto-loading configuration files.

They're loaded in this order, and when a configuration option is present in more than one file the last file takes precedence.

Since 1.12: Additionally configuration files can be loaded manually with the --config (-C) command-line option, e.g. $ vcs -C myconfig.cfg. Files will need to have a comment like # vcs:conf: near the beginning or end to be accepted by --config.

Configuration files follow a simplified shell-like syntax:

  • Configuration options are set as SETTING=VALUE. Spaces in the value are allowed. Don't quote the value unless you want quotes displayed.
  • Everything following a ‘#’ or ‘;’ are comments (and are ignored).
    • Use ‘$#’ to put # in a value
    • ; is always ignored
  • Options not recognised will be ignored

Certain setings have no equivalent command-line option. They can be set from the command-line by using the special option -O (--override) followed by OPTION=VALUE. In general, customisation of the script shouldn't require any editing of the script itself.

Examples

  • Setting background colour for the heading to blue: bg_heading=blue. Added to a configuration file or from the command-line: $ vcs -O 'bg_heading=blue' file.avi
  • Output to JPEG by default: format=jpg. Added to a configuration file (the command-line option -j does the same for a single run).

Example configuration file

# Output to JPEG...
format=jpg
# ...with 90% quality
quality=90
# Sign as "myname"
user=myname
# Use "Snapshots grabbed by myname" instead of "Preview created by myname"
signature=Snapshots grabbed by

List of options

These are the accepted options in 1.12, previous versions had different names

  • Option names are case insensitive
  • font_filename was removed in 1.12 as part of the reworked handling of non-latin filename, next version will provide an alternative

Integer in Additional details means the value can only accept numeric values.

Option Default Description Additional details
Main behaviour options
interval 300 Default capture interval Time
numcaps 16 Default number of captures Integer
columns 2 Default number of columns Integer
padding 2 Padding between captures Integer
height Height Can be a fixed value or a percentage. By default same as input
signature “Preview created by” Text before the user name in the signature
user $(id -un) 2) User name for signature. See -u (--user) and -U (--fullname)
format png Sets the output format Should match the extension of a format known by ImageMagick
quality 92 Image quality for output in lossy formats Integer, Only affects the final image
decoder $DEC_FFMPEG Controls which capturer to use by default Symbolic: $DEC_FFMPEG ⇒ FFmpeg, $DEC_MPLAYER ⇒ MPlayer
timecode_from $TC_INTERVAL Selects between number of captures or interval mode Symbolic: $TC_INTERVAL ⇒ interval mode, $TC_NUMCAPS ⇒ number of captures mode
extended_factor 0 Set the extended factor. 0 disables extended mode.
See extended_mode
disable_shadows 0 Disables drop shadows when 1. Equivalent command-line argument -ds.
