GLib guarantees libintl is always present, using proxy-libintl as last resort. There is no need to mock gettex API any more. This fix static build on Windows because G_INTL_STATIC_COMPILATION must be defined before including libintl.h, and glib does it for us as part as including glib.h.

|
|
* @short_description: General Application and Plugin Utility Library
|
|
*
|
|
* libgstpbutils is a general utility library for plugins and applications.
|
|
* It currently provides the
|
|
* following:
|
|
*
|
|
* * human-readable description strings of codecs, elements, sources, decoders,
|
|
* encoders, or sinks from decoder/encoder caps, element names, or protocol
|
|
* names.
|
|
*
|
|
* * support for applications to initiate installation of missing plugins (if
|
|
* this is supported by the distribution or operating system used)
|
|
*
|
|
* * API for GStreamer elements to create missing-plugin messages in order to
|
|
* communicate to the application that a certain type of plugin is missing
|
|
* (decoder, encoder, URI protocol source, URI protocol sink, named element)
|
|
*
|
|
* * API for applications to recognise and handle missing-plugin messages
|
|
*
|
|
* ## Linking to this library
|
|
*
|
|
* You should obtain the required CFLAGS and LIBS using pkg-config on the
|
|
* gstreamer-plugins-base-1.0 module. You will then also need to add
|
|
* '-lgstreamer-pbutils-1.0' manually to your LIBS line.
|
|
*
|
|
* ## Library initialisation
|
|
*
|
|
* Before using any of its functions, applications and plugins must call
|
|
* gst_pb_utils_init() to initialise the library.
|
|
