This interface abstracts handling of property sets for elements with
children. Imagine elements such as mixers or polyphonic generators. They all
have multiple |
Clock |
GStreamer uses a global clock to synchronize the plugins in a pipeline.
Different clock implementations are possible by implementing this abstract
base class or, more conveniently, by subclassing |

Padtemplates describe the possible media types a pad or an elementfactory can handle. This allows for both inspection of handled types before loading the element plugin as well as identifying pads on elements that are not yet created (request or sometimes pads). |

Preset |
This interface offers methods to query and manipulate parameter preset sets. A preset is a bunch of property settings, together with meta data and a name. The name of a preset serves as key for subsequent method calls to manipulate single presets. All instances of one type will share the list of presets. The list is created on demand, if presets are not used, the list is not created. |

A high-level object representing a single stream. It might be backed, or
not, by an actual flow of data in a pipeline ( |
StreamCollection |
A collection of |
StreamFlags | |
StreamType | |
SystemClock |
The GStreamer core provides a GstSystemClock based on the system time. Asynchronous callbacks are scheduled from an internal thread. |
TagSetter |
Element interface that allows setting of media metadata. |
TocSetter |
Element interface that allows setting of the TOC. |
TypeFind | |
TypeFindFactory |
These functions allow querying informations about registered typefind
functions. How to create and register these functions is described in
the section
"Writing typefind functions" |
TypedValue |
A statically typed |
URIHandler |
The |
Value |
A generic value capable of carrying various types. |
Enums
BufferingMode |
The different types of buffering methods. |
BusSyncReply |
The result values for a GstBusSyncHandler. |
CapsIntersectMode |
Modes of caps intersection |
ClockError | |
ClockReturn |
The return value of a clock operation. |
ClockSuccess | |
ClockType |
The different kind of clocks. |
CoreError |
Core errors are errors inside the core GStreamer library. |
DebugLevel |
The level defines the importance of a debugging message. The more important a message is, the greater the probability that the debugging system outputs it. |
ElementMessageType | |
EventType |
|
FlowError | |
FlowReturn |
The result of passing data to a pad. |
FlowSuccess | |
Format |
Standard predefined formats |
IteratorError | |
LibraryError |
Library errors are for errors from the library being used by elements (initializing, finalizing, settings, ...) |
PadDirection |
The direction of a pad. |
PadLinkError | |
PadLinkReturn |
Result values from gst_pad_link and friends. |
PadMode |
The status of a GstPad. After activating a pad, which usually happens when the parent element goes from READY to PAUSED, the GstPadMode defines if the pad operates in push or pull mode. |
PadPresence |
Indicates when this pad will become available. |
PadProbeData | |
PadProbeReturn |
Different return values for the |
ParseError |
The different parsing errors that can occur. |
PluginError |
The plugin loading errors |
ProgressType |
The type of a |
PromiseResult |
The result of a |
QOSType |
The different types of QoS events that can be given to the
|
Rank |
Element priority ranks. Defines the order in which the autoplugger (or
similar rank-picking mechanisms, such as e.g. |
ResourceError |
Resource errors are for any resource used by an element: memory, files, network connections, process space, ... They're typically used by source and sink elements. |
SeekType |
The different types of seek events. When constructing a seek event with
|
State |
The possible states an element can be in. States can be changed using
|
StateChange |
These are the different state changes an element goes through.
|
StateChangeReturn |
The possible return values from a state change function such as
|
StateChangeSuccess | |
StreamError |
Stream errors are for anything related to the stream being processed: format errors, media type errors, ... They're typically used by decoders, demuxers, converters, ... |
StreamStatusType |
The type of a |
StructureChangeType |
The type of a |
TagError | |
TagMergeMode |
The different tag merging modes are basically replace, overwrite and append,
but they can be seen from two directions. Given two taglists: (A) the tags
already in the element and (B) the ones that are supplied to the element (
e.g. via |
