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 occured.

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 occured.

MESSAGE_INFO 

An info message occured.

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_ANY 

Mask for all of the above messages.

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.

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:

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
argcReference to application's argc.
argvReference 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:

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:

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
argcReference to application's argc.
argvReference 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:

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

: whether rebuilding the registry can use a temporary child helper process.

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.
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.

: whether a custom SIGSEGV handler should be installed.

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

Gets the version number of the gstreamermm library.

Parameters
majorPointer to a guint to store the major version number.
minorPointer to a guint to store the minor version number.
microPointer to a guint to store the micro version number.
void Gst::version ( guint &  major,
guint &  minor,
guint &  micro,
guint &  nano 
)

Gets the version number of the GStreamer library.

: (out): pointer to a guint to store the major version number : (out): pointer to a guint to store the minor version number : (out): pointer to a guint to store the micro version number : (out): pointer to a guint to store the nano version number

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.
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 
)
