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.

Returns:
  The quark associated with the resource error domain.

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

Gets the seconds component of Gst::ClockTime.

Parameters:

  | time | The Gst::ClockTime to parse.

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::gst_wrap_init | ( |  | ) |

Initializes the wrapping system of Gst::MiniObject-derived classes.

There is no need to use this function directly. Instead use Gst::init() or Gst::init_check().

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.

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.

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::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 |

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.
