=head1 NAME

dh_gstscancodecs - enumerate and classify gstreamer codecs

=cut

use strict;
use Debian::Debhelper::Dh_Lib;
use File::Temp;

=head1 SYNOPSIS

  dh_gstscancodecs [debhelper options]

=head1 DESCRIPTION

This program is meant to assist in building a package that provides
codecs, demultiplexers and other media-handling components for
gstreamer-based applications.

dh_gstscancodecs generates substitution variable for debian/control,
by scanning libraries /usr/lib/gstreamer-1.0/*.so and
/usr/lib/$DEB_HOST_MULTIARCH/gstreamer-1.0/*.so.

The generated substitution variables are

=over 4

=item gstreamer:Version

Should be added to XB-GStreamer-Version

=item gstreamer:Elements

Should be added to XB-GStreamer-Elements

=item gstreamer:Provides

Should be added to Provides

=item gstreamer:URISources

Should be added to XB-GStreamer-URI-Sources

=item gstreamer:URISinks

Should be added to XB-GStreamer-URI-Sinks

=item gstreamer:Encoders

Should be added to XB-GStreamer-Encoders

=item gstreamer:Decoders

Should be added to XB-GStreamer-Decoders

=back

This control fields will be used by the /usr/bin/gstreamer-codec-install
helper to install required missing GStreamer elements.

=head1 OPTIONS

The standard debhelper options are supported.
