## Function Documentation

## ◆ deinit()

void Gst::deinit | ( |  | ) |

Clean up any resources created by GStreamer upon initialization.

It is normally not needed to call this function in a normal application as the resources will automatically be freed when the program terminates. This function is therefore mostly used by testsuites and other memory profiling tools.

After this call GStreamer (including this method) should not be used anymore.

## ◆ formats_contain()

|  | Format | format
| ) |  |

Sees if the given format is inside the array of formats.

Parameters

  formats | The array of formats to search.
  format | The format to find.

Returns
  true If the format is found inside the array.

## ◆ init() [1/2]

void Gst::init | ( | int & | argc,
|  | char **& | argv
| ) |  |

Initializes gstreamermm parsing command line arguments.

Either this function or Gst::init_check() with command line parsing should be called to initialize gstreamermm before calling any other GLib functions. If this is not an option, your program must initialize the GLib thread system using Glib::thread_init() before any other GLib functions are called and use either Gst::init(), or Gst::init_check() without the command line arguments before calling any gstreamermm functions.

Note: This function will terminate your program if it was unable to initialize GStreamer for some reason. If you want your program to fall back, use Gst::init_check() instead.

WARNING: This function does not work in the same way as corresponding functions in other glib-style libraries, such as gtk_init(). In particular, unknown command line options cause this function to abort program execution.

Parameters

  argc | Reference to application's argc.
  argv | Reference to application's argv.

Examples:
  basics/bin.cc, basics/bus.cc, basics/dynamic_pads.cc, basics/element_factory.cc, and basics/init_gstreamermm.cc.

## ◆ init() [2/2]

void Gst::init | ( |  | ) |

Initializes gstreamermm without parsing command line options.

Either the Gst::init() or Gst::init_check() functions with command line parsing should be called to initialize gstreamermm before calling any other GLib functions. If this is not an option, your program must initialize the GLib thread system using Glib::thread_init() before any other GLib functions are called and use either this function or Gst::init_check() without the command line arguments before calling any gstreamermm functions.

Note: This function will terminate your program if it was unable to initialize GStreamer for some reason. If you want your program to fall back, use Gst::init_check() instead.

## ◆ init_check() [1/2]

bool Gst::init_check | ( | int & | argc,
|  | char **& | argv
| ) |  |

Initializes gstreamermm gracefully parsing command line arguments.

Either this function or Gst::init() with command line parsing should be called to initialize gstreamermm before calling any other GLib functions. If this is not an option, your program must initialize the GLib thread system using Glib::thread_init() before any other GLib functions are called and use either Gst::init() or Gst::init_check() without the command line arguments before calling any gstreamermm functions.

This function will return false if GStreamer could not be initialized for some reason. If you want your program to fail fatally, use Gst::init() instead.

Parameters

  argc | Reference to application's argc.
  argv | Reference to application's argv.

Returns
  true if GStreamer could be initialized.

Exceptions

  Glib::Error |

## ◆ init_check() [2/2]

bool Gst::init_check | ( |  | ) |

Initializes gstreamermm gracefully without parsing command line arguments.

Either the Gst::init() or Gst::init_check() functions with command line parsing should be called to initialize gstreamermm before calling any other GLib functions. If this is not an option, your program must initialize the GLib thread system using Glib::thread_init() before any other GLib functions are called and use either this function or Gst::init() without the command line arguments before calling any gstreamermm functions.

This function will return false if GStreamer could not be initialized for some reason. If you want your program to fail fatally, use Gst::init() instead.

Returns
  true if GStreamer could be initialized.

Exceptions

  Glib::Error |

## ◆ is_initialized()

bool Gst::is_initialized | ( | void |  | ) |

Use this function to check if GStreamer has been initialized.

Returns
  `true` if initialization has been done, `false` otherwise.

## ◆ iterate_format_definitions()

IteratorBasic<const FormatDefinition> Gst::iterate_format_definitions | ( |  | ) |

Iterates all the registered formats.

The format definitions are read only.

Returns
  a Gst::IteratorBasic of Gst::FormatDefinition.

## ◆ operator<<()

std::ostream& Gst::operator<< | ( | std::ostream & | stream,
|  | Tag | tag
| ) |  |

An Output stream operator for the Gst::Tag enum (this will output a string).

## ◆ register_format()

Format Gst::register_format | ( | const Glib::ustring & | nick,
|  | const Glib::ustring & | description
| ) |  |

Creates a new Gst::Format based on the nick or return an already registered format with that nick.

Parameters

  nick | The nick of the new format.
  description | The description of the new format.

Returns
  A new Gst::Format or an already registered format with the same nick. MT safe.

## ◆ registry_fork_is_enabled()

bool Gst::registry_fork_is_enabled | ( |  | ) |

By default GStreamer will perform scanning and rebuilding of the registry file using a helper child process.

Applications might want to disable this behaviour with the gst_registry_fork_set_enabled() function, in which case new plugins are scanned (and loaded) into the application process.

Returns
  `true` if GStreamer will use the child helper process when rebuilding the registry.

## ◆ registry_fork_set_enabled()

void Gst::registry_fork_set_enabled | ( | bool | enabled | ) |

Applications might want to disable/enable spawning of a child helper process when rebuilding the registry.

See gst_registry_fork_is_enabled() for more information.

Parameters

  enabled | Whether rebuilding the registry can use a temporary child helper process.

## ◆ segtrap_is_enabled()

bool Gst::segtrap_is_enabled | ( |  | ) |

Some functions in the GStreamer core might install a custom SIGSEGV handler to better catch and report errors to the application.

Currently this feature is enabled by default when loading plugins.

Applications might want to disable this behaviour with the gst_segtrap_set_enabled() function. This is typically done if the application wants to install its own handler without GStreamer interfering.

Returns
  `true` if GStreamer is allowed to install a custom SIGSEGV handler.

## ◆ segtrap_set_enabled()

void Gst::segtrap_set_enabled | ( | bool | enabled | ) |

Applications might want to disable/enable the SIGSEGV handling of the GStreamer core.

See gst_segtrap_is_enabled() for more information.

Parameters

  enabled | Whether a custom SIGSEGV handler should be installed.

## ◆ update_registry()

bool Gst::update_registry | ( |  | ) |

Forces GStreamer to re-scan its plugin paths and update the default plugin registry.

Applications will almost never need to call this function, it is only useful if the application knows new plugins have been installed (or old ones removed) since the start of the application (or, to be precise, the first call to gst_init()) and the application wants to make use of any newly-installed plugins without restarting the application.

Applications should assume that the registry update is neither atomic nor thread-safe and should therefore not have any dynamic pipelines running (including the playbin and decodebin elements) and should also not create any elements or access the GStreamer registry while the update is in progress.

Note that this function may block for a significant amount of time.

Returns
  `true` if the registry has been updated successfully (does not imply that there were changes), otherwise `false`.

## ◆ version() [1/2]

void Gst::version | ( | guint & | major,

|  | guint & | minor,
|  | guint & | micro,
|  | guint & | nano
| ) |  |

Gets the version number of the GStreamer library.

Parameters

## ◆ version_string()

Glib::ustring Gst::version_string | ( |  | ) |

This function returns a string that is useful for describing this version of GStreamer to the outside world: user agent strings, logging, ...

Returns
  A newly allocated string describing this version of GStreamer.

## ◆ wrap_init()

void Gst::wrap_init | ( |  | ) |

Initializes the main gstreamermm wrapping system.

There's no need to use this function directly; instead use Gst::init() or Gst::init_check().

## ◆ wrap_msg_derived()

template <typename T >

Glib::RefPtr<T> Gst::wrap_msg_derived | ( | GstMessage * | object,
|  | bool | take_copy
