FORMAT_DEFAULT | The default format of the pad/element. This can be samples for raw audio, frames/fields for raw video (some, but not all, elements support this; use GST_FORMAT_TIME if you don't have a good reason to query for samples/frames).
FORMAT_BYTES | Bytes.
FORMAT_TIME | Time in nanoseconds.
FORMAT_BUFFERS | Buffers (few, if any, elements implement this as of May 2009).
FORMAT_PERCENT | Percentage of stream (few, if any, elements implement this as of May 2009).

## ◆ MessageType

enum Gst::MessageType

Enumerator
MESSAGE_UNKNOWN | An undefined message.
MESSAGE_EOS | End-of-stream reached in a pipeline. The application will only receive this message in the PLAYING state and every time it sets a pipeline to PLAYING that is in the EOS state. The application can perform a flushing seek in the pipeline, which will undo the EOS state again.
MESSAGE_ERROR | An error occurred. When the application receives an error message it should stop playback of the pipeline and not assume that more data will be played.
MESSAGE_WARNING | A warning occurred.
MESSAGE_INFO | An info message occurred.
MESSAGE_TAG | A tag was found.
MESSAGE_BUFFERING | The pipeline is buffering. When the application receives a buffering message in the PLAYING state for a non-live pipeline it must PAUSE the pipeline until the buffering completes, when the percentage field in the message is 100%. For live pipelines, no action must be performed and the buffering percentage can be used to inform the user about the progress.
MESSAGE_STATE_CHANGED | A state change happened.
MESSAGE_STATE_DIRTY | An element changed state in a streaming thread. This message is deprecated.
MESSAGE_STEP_DONE | A stepping operation finished.
MESSAGE_CLOCK_PROVIDE | An element notifies its capability of providing a clock. This message is used internally and never forwarded to the application.
MESSAGE_CLOCK_LOST | The current clock as selected by the pipeline became unusable. The pipeline will select a new clock on the next PLAYING state change. The application should set the pipeline to PAUSED and back to PLAYING when this message is received.
MESSAGE_NEW_CLOCK | A new clock was selected in the pipeline.
MESSAGE_STRUCTURE_CHANGE | The structure of the pipeline changed. This message is used internally and never forwarded to the application.
MESSAGE_STREAM_STATUS | Status about a stream, emitted when it starts, stops, errors, etc..
MESSAGE_APPLICATION | Message posted by the application, possibly via an application-specific element.
MESSAGE_ELEMENT | Element-specific message, see the specific element's documentation.
MESSAGE_SEGMENT_START | Pipeline started playback of a segment. This message is used internally and never forwarded to the application.
MESSAGE_SEGMENT_DONE | Pipeline completed playback of a segment. This message is forwarded to the application after all elements that posted GST_MESSAGE_SEGMENT_START posted a GST_MESSAGE_SEGMENT_DONE message.
MESSAGE_DURATION_CHANGED | The duration of a pipeline changed. The application can get the new duration with a duration query.
MESSAGE_LATENCY | Posted by elements when their latency changes. The application should recalculate and distribute a new latency.
MESSAGE_ASYNC_START | Posted by elements when they start an ASYNC Gst::StateChange. This message is not forwarded to the application but is used internally.
MESSAGE_ASYNC_DONE | Posted by elements when they complete an ASYNC Gst::StateChange. The application will only receive this message from the toplevel pipeline.
MESSAGE_REQUEST_STATE | Posted by elements when they want the pipeline to change state. This message is a suggestion to the application which can decide to perform the state change on (part of) the pipeline.
MESSAGE_STEP_START | A stepping operation was started.
MESSAGE_QOS | A buffer was dropped or an element changed its processing strategy for Quality of Service reasons.
MESSAGE_PROGRESS | A progress message.
MESSAGE_TOC | A new table of contents (TOC) was found or previously found TOC was updated.
MESSAGE_RESET_TIME | Message to request resetting the pipeline's running time from the pipeline. This is an internal message which applications will likely never receive.
MESSAGE_STREAM_START | Message indicating start of a new stream. Useful e.g. when using playbin in gapless playback mode, to get notified when the next title actually starts playing (which will be some time after the URI for the next title has been set).
MESSAGE_NEED_CONTEXT | Message indicating that an element wants a specific context (Since 1.2).
MESSAGE_HAVE_CONTEXT | Message indicating that an element created a context (Since 1.2).
MESSAGE_EXTENDED | Message is an extended message type (see below). These extended message IDs can't be used directly with mask-based API like Gst::Bus::poll() or Gst::Bus::timed_pop_filtered(), but you can still filter for GST_MESSAGE_EXTENDED and then check the result for the specific type. (Since 1.4).

## ◆ get_nanoseconds()

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

Gets the nanoseconds component of Gst::ClockTime.

Parameters

  time | The Gst::ClockTime to parse.

Returns
  The nanoseconds component of the Gst::ClockTime.

## ◆ get_option_group()

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.

Examples
  basics/init_gstreamermm.cc.

## ◆ get_resource_error_quark()

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

Gets error domain for resource handling.

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

Returns
  The quark associated with the resource error domain.

## ◆ get_seconds()

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

Gets the seconds component of Gst::ClockTime.

Parameters

  time | The Gst::ClockTime to parse.

Returns
  The seconds component of the Gst::ClockTime.

## ◆ get_stream_error_quark()

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.

## ◆ init() [1/2]

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() [2/2]

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_check() [1/2]

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 |

## ◆ init_check() [2/2]

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 |

## ◆ 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]

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()
