## Function Documentation

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.

bool Gst::formats_contain | ( | const Glib::ArrayHandle< Format > & | formats,
|  | 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.

Glib::QueryQuark Gst::get_core_error_quark | ( |  | ) |

Gets the error domain for core system.

Errors in this domain will be from the Gst::CoreError enumeration.

Returns
  The quark associated with the core error domain.

Format Gst::get_format | ( | const Glib::ustring & | nick | ) |

Returns the format registered with the given nick.

Parameters

  nick | The nick of the format.

Returns
  The format with nick or Gst::FORMAT_UNDEFINED if the format was not registered.

bool Gst::get_format_details | ( | Format | format,
|  | FormatDefinition & | def
| ) |  |

Gets details about the given format.

Parameters

  format | The format to get details of.
  def | The Gst::FormatDefinition in which to store the details of the format.

Returns
  true if successful, false otherwise. MT safe.

guint Gst::get_fractional_seconds | ( | ClockTime | time | ) |

Gets the fractional component (milli, micro and nano seconds) of Gst::ClockTime.

Parameters

  time | The Gst::ClockTime to parse.

Returns
  The fractional component of the Gst::ClockTime.

guint Gst::get_hours | ( | ClockTime | time | ) |

Gets the hour component of Gst::ClockTime.

  The quark associated with the library error domain.

guint Gst::get_microseconds | ( | ClockTime | time | ) |

Gets the microseconds component of Gst::ClockTime.

Parameters

  time | The Gst::ClockTime to parse.

Returns
  The microseconds component of the Gst::ClockTime.

guint Gst::get_milliseconds | ( | ClockTime | time | ) |

Gets the milliseconds component of Gst::ClockTime.

Parameters

  time | The Gst::ClockTime to parse.

Returns
  The milliseconds component of the Gst::ClockTime.

Returns
  The nanoseconds component of the Gst::ClockTime.

Glib::OptionGroup Gst::get_option_group | ( |  | ) |

Returns a Glib::OptionGroup with GStreamer's argument specifications.

The group is set up to use standard GOption callbacks, so when using this group in combination with GOption parsing methods, all argument parsing and initialization is automated.

This function is useful if you want to integrate GStreamer with other libraries that use GOption (see g_option_context_add_group() ).

If you use this function, you should make sure you initialise the GLib threading system as one of the very first things in your program.

Returns
  A pointer to GStreamer's option group.

Glib::QueryQuark Gst::get_resource_error_quark | ( |  | ) |

Gets error domain for resource handling.

Returns
  The seconds component of the Gst::ClockTime.

Glib::QueryQuark Gst::get_stream_error_quark | ( |  | ) |

Gets error domain for media stream processing.

Errors in this domain will be from the Gst::StreamError enumeration.

Returns
  The quark associated with the media stream error domain.

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. GLib thread initialization can be done as follows:

if(!Glib::thread_supported())
Glib::thread_init();
...

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.

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. GLib thread initialization can be done as follows:

if(!Glib::thread_supported())
Glib::thread_init();
...

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.

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. GLib thread initialization can be done as follows:

if(!Glib::thread_supported())
Glib::thread_init();
...

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 |

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. GLib thread initialization can be done as follows:

if(!Glib::thread_supported())
Glib::thread_init();
...

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 |

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

Use this function to check if GStreamer has been initialized.

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

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.

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

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

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.

void Gst::version | ( | guint & | major,
|  | guint & | minor,
|  | guint & | micro
| ) |  |

Gets the version number of the gstreamermm library.

Parameters

  major | Pointer to a guint to store the major version number.
  minor | Pointer to a guint to store the minor version number.
  micro | Pointer to a guint to store the micro version number.

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().

template <typename T >

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