In almost all cases, you'll want to use a GstPipeline when creating a

filter graph. The GstPipeline will manage all the scheduling issues,

including threading, as well as provide simple interfaces to common

functions, like 'Play'.

the pipeline, use gst_object_unref() to free its resources.

A plugin should export a symbol <symbol>plugin_desc</symbol> that is a struct of type #GstPluginDesc.

the plugin loader will check the version of the core library the plugin was linked against

Usually plugins are always automaticlly loaded so you don't need to call gst_plugin_load() explicitly

to bring it into memory. There are options to statically link plugins to an app or even

use GStreamer without a plugin repository in which case gst_plugin_load() can be needed

to bring the plugin into memory.

|
*
|

|
* A plugin should export a symbol <symbol>plugin_desc</symbol> that is a struct of type #GstPluginDesc.
|

|
* the plugin loader will check the version of the core library the plugin was linked against
|
||||||
|
* and will create a new #GstPlugin. It will then call the #GstPluginInitFunc function
|

|
* that was provided in the plugin_desc.
|

|
*
|

|
* Once you have a handle to a #GstPlugin (e.g. from the #GstRegistryPool), you can

* Usually plugins are always automaticlly loaded so you don't need to call gst_plugin_load() explicitly

|
* use GStreamer without a plugin repository in which case gst_plugin_load() can be needed
