|
|
* @short_description: GStreamer version macros.
|
|
*
|
|
* Use the GST_VERSION_* macros e.g. when defining own plugins. The GStreamer
|
|
* runtime checks if these plugin and core version match and refuses to use a
|
|
* plugin compiled against a different version of GStreamer.
|
|
* You can also use the macros to keep the GStreamer version information in
|
|
* your application.
|
|
*
|
|
* Use the gst_version() function if you want to know which version of
|
|
* GStreamer you are currently linked against.
|
|
*
|
|
* The version macros get defined by including "gst/gst.h".
