BinFlags
GstBinFlags are a set of flags specific to bins. Most are set/used internally. They can be checked using the GST_OBJECT_FLAG_IS_SET () macro, and (un)set using GST_OBJECT_FLAG_SET () and GST_OBJECT_FLAG_UNSET ().
Constructors
| BinFlagsNoResync | don't resync a state change when elements are added or linked in the bin (Since: 1.0.5) |
| BinFlagsStreamsAware | Indicates whether the bin can handle elements that add/remove source pads at any point in time without first posting a no-more-pads signal (Since: 1.10) |

data BufferFlags Source #
A set of buffer flags used to describe properties of a Buffer.
Constructors
| BufferFlagsLive | the buffer is live data and should be discarded in the PAUSED state. |
| BufferFlagsDecodeOnly | the buffer contains data that should be dropped because it will be clipped against the segment boundaries or because it does not contain data that should be shown to the user. |
| BufferFlagsDiscont | the buffer marks a data discontinuity in the stream. This typically occurs after a seek or a dropped buffer from a live or network source. |
| BufferFlagsResync | the buffer timestamps might have a discontinuity and this buffer is a good point to resynchronize. |
| BufferFlagsCorrupted | the buffer data is corrupted. |
| BufferFlagsMarker | the buffer contains a media specific marker. for video this is the end of a frame boundary, for audio this is the start of a talkspurt. |
| BufferFlagsHeader | the buffer contains header information that is needed to decode the following data. |
| BufferFlagsGap | the buffer has been created to fill a gap in the stream and contains media neutral data (elements can switch to optimized code path that ignores the buffer content). |
| BufferFlagsDroppable | the buffer can be dropped without breaking the stream, for example to reduce bandwidth. |
| BufferFlagsDeltaUnit | this unit cannot be decoded independently. |
| BufferFlagsTagMemory | this flag is set when memory of the buffer is added/removed |
| BufferFlagsSyncAfter | Elements which write to disk or permanent storage should ensure the data is synced after writing the contents of this buffer. (Since: 1.6) |
| BufferFlagsNonDroppable | This buffer is important and should not be dropped. This can be used to mark important buffers, e.g. to flag RTP packets carrying keyframes or codec setup data for RTP Forward Error Correction purposes, or to prevent still video frames from being dropped by elements due to QoS.

MessageType
data MessageType Source #
The different message types that are available.
Constructors
| MessageTypeUnknown | an undefined message |
| MessageTypeEos | 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. |
| MessageTypeError | 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. It is possible to specify a redirection url to the error
messages by setting a |
| MessageTypeWarning | a warning occurred. |
| MessageTypeInfo | an info message occurred |
| MessageTypeTag | a tag was found. |
| MessageTypeBuffering | 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. |
| MessageTypeStateChanged | a state change happened |
| MessageTypeStateDirty | an element changed state in a streaming thread. This message is deprecated. |
| MessageTypeStepDone | a stepping operation finished. |
| MessageTypeClockProvide | an element notifies its capability of providing a clock. This message is used internally and never forwarded to the application. |
| MessageTypeClockLost | 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. |
| MessageTypeNewClock | a new clock was selected in the pipeline. |
| MessageTypeStructureChange | the structure of the pipeline changed. This message is used internally and never forwarded to the application. |
| MessageTypeStreamStatus | status about a stream, emitted when it starts, stops, errors, etc.. |
| MessageTypeApplication | message posted by the application, possibly via an application-specific element. |
| MessageTypeElement | element-specific message, see the specific element's documentation |
| MessageTypeSegmentStart | pipeline started playback of a segment. This message is used internally and never forwarded to the application. |
| MessageTypeSegmentDone | pipeline completed playback of a segment. This
message is forwarded to the application after all elements that posted
|
| MessageTypeDurationChanged | The duration of a pipeline changed. The application can get the new duration with a duration query. |
| MessageTypeLatency | Posted by elements when their latency changes. The application should recalculate and distribute a new latency. |
| MessageTypeAsyncStart | Posted by elements when they start an ASYNC
|
| MessageTypeAsyncDone | Posted by elements when they complete an ASYNC
|
| MessageTypeRequestState | 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. |
| MessageTypeStepStart | A stepping operation was started. |
| MessageTypeQos | A buffer was dropped or an element changed its processing strategy for Quality of Service reasons. |
| MessageTypeProgress | A progress message. |
| MessageTypeToc | A new table of contents (TOC) was found or previously found TOC was updated. |
| MessageTypeResetTime | Message to request resetting the pipeline's running time from the pipeline. This is an internal message which applications will likely never receive. |
| MessageTypeStreamStart | 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). |
| MessageTypeNeedContext | Message indicating that an element wants a specific context (Since: 1.2) |
| MessageTypeHaveContext | Message indicating that an element created a context (Since: 1.2) |
| MessageTypeExtended | Message is an extended message type (see below).
These extended message IDs can't be used directly with mask-based API
like |
| MessageTypeDeviceAdded | Message indicating a |
| MessageTypeDeviceRemoved | Message indicating a |
| MessageTypePropertyNotify | Message indicating a |
| MessageTypeStreamCollection | Message indicating a new |
| MessageTypeStreamsSelected | Message indicating the active selection of
|
| MessageTypeRedirect | Message indicating to request the application to try to play the given URL(s). Useful if for example a HTTP 302/303 response is received with a non-HTTP URL inside. (Since: 1.10) |
| MessageTypeDeviceChanged | Message indicating a |
| MessageTypeInstantRateRequest | Message sent by elements to request the running time from the pipeline when an instant rate change should be applied (which may be in the past when the answer arrives). (Since: 1.18) |
| MessageTypeAny | mask for all of the above messages. |

| PadFlagsPendingEvents | the pad has pending events |
| PadFlagsFixedCaps | the pad is using fixed caps. This means that once the caps are set on the pad, the default caps query function will only return those caps. |
| PadFlagsProxyCaps | the default event and query handler will forward all events and queries to the internally linked pads instead of discarding them. |
| PadFlagsProxyAllocation | the default query handler will forward allocation queries to the internally linked pads instead of discarding them. |
| PadFlagsProxyScheduling | the default query handler will forward scheduling queries to the internally linked pads instead of discarding them. |

| PadFlagsAcceptTemplate | the default accept-caps handler will use
the template pad caps instead of query caps to
compare with the accept caps. Use this in combination

PadLinkCheck
data PadLinkCheck Source #
The amount of checking to be done when linking pads. gSTPADLINKCHECKCAPS
and gSTPADLINKCHECKTEMPLATECAPS are mutually exclusive. If both are
specified, expensive but safe gSTPADLINKCHECKCAPS are performed.
Only disable some of the checks if you are 100% certain you know the link

Instances
SeekFlags
Flags to be used with elementSeek or eventNewSeek. All flags
can be used together.
A non flushing seek might take some time to perform as the currently playing data in the pipeline will not be cleared.
An accurate seek might be slower for formats that don't have any indexes or timestamp markers in the stream. Specifying this flag might require a complete scan of the file in those cases.
When performing a segment seek: after the playback of the segment completes,
no EOS will be emitted by the element that performed the seek, but a
MessageTypeSegmentDone message will be posted on the bus by the element.
When this message is posted, it is possible to send a new seek event to
continue playback. With this seek method it is possible to perform seamless
looping or simple linear editing.
When only changing the playback rate and not the direction, the
SeekFlagsInstantRateChange flag can be used for a non-flushing seek
to signal that the rate change should be applied immediately. This requires
special support in the seek handlers (e.g. demuxers) and any elements
synchronizing to the clock, and in general can't work in all cases (for example
UDP streaming where the delivery rate is controlled by a remote server). The
instant-rate-change mode supports changing the trickmode-related GST_SEEK_ flags,
but can't be used in conjunction with other seek flags that affect the new
playback position - as the playback position will not be changing.
When doing fast forward (rate > 1.0) or fast reverse (rate < -1.0) trickmode
playback, the SeekFlagsTrickmode flag can be used to instruct decoders
and demuxers to adjust the playback rate by skipping frames. This can improve
performance and decrease CPU usage because not all frames need to be decoded.
Beyond that, the SeekFlagsTrickmodeKeyUnits flag can be used to
request that decoders skip all frames except key units, and
SeekFlagsTrickmodeNoAudio flags can be used to request that audio
decoders do no decoding at all, and simple output silence.
The SeekFlagsSnapBefore flag can be used to snap to the previous
relevant location, and the SeekFlagsSnapAfter flag can be used to
select the next relevant location. If SeekFlagsKeyUnit is specified,
the relevant location is a keyframe. If both flags are specified, the nearest
of these locations will be selected. If none are specified, the implementation is
free to select whichever it wants.
The before and after here are in running time, so when playing backwards, the next location refers to the one that will played in next, and not the one that is located after in the actual source stream.
Also see part-seeking.txt in the GStreamer design documentation for more details on the meaning of these flags and the behaviour expected of elements that handle them.
Constructors
| SeekFlagsNone | no flag |

| SeekFlagsTrickmodeKeyUnits | when doing fast forward or fast reverse playback, request that elements only decode keyframes and skip all other content, for formats that have keyframes. (Since: 1.6) |
| SeekFlagsTrickmodeNoAudio | when doing fast forward or fast reverse playback, request that audio decoder elements skip decoding and output only gap events or silence. (Since: 1.6) |
| SeekFlagsTrickmodeForwardPredicted | When doing fast forward or fast reverse playback, request that elements only decode keyframes and forward predicted frames and skip all other content (for example B-Frames), for formats that have keyframes and forward predicted frames. (Since: 1.18) |
| SeekFlagsInstantRateChange | Signals that a rate change should be applied immediately. Only valid if start/stop position are GST_CLOCK_TIME_NONE, the playback direction does not change and the seek is not flushing. (Since: 1.18) |
