BinFlags

data BinFlags Source #

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)

BinFlagsLast

the last enum in the series of flags for bins. Derived classes can use this as first value in a list of flags.

flag indicating that buffer meta should be copied

BufferCopyFlagsMemory

flag indicating that buffer memory should be reffed and appended to already existing memory. Unless the memory is marked as NO_SHARE, no actual copy of the memory is made but it is simply reffed. Add gSTBUFFERCOPYDEEP to force a real copy.

BufferCopyFlagsMerge

flag indicating that buffer memory should be merged

BufferCopyFlagsDeep

flag indicating that memory should always be copied instead of reffed (Since: 1.2)

BufferFlags

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. (Since: 1.14)

BufferFlagsLast

additional media specific flags can be added starting from this flag.

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 redirect-location field into the error message, application or high level bins might use the information as required.

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 gSTMESSAGESEGMENTSTART posted a GST_MESSAGE_SEGMENT_DONE message.

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 StateChange. This message is not forwarded to the application but is used internally.

MessageTypeAsyncDone

Posted by elements when they complete an ASYNC StateChange. The application will only receive this message from the toplevel pipeline.

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 busPoll or busTimedPopFiltered, but you can still filter for GST_MESSAGE_EXTENDED and then check the result for the specific type. (Since: 1.4)

MessageTypeDeviceAdded

Message indicating a Device was added to a DeviceProvider (Since: 1.4)

MessageTypeDeviceRemoved

Message indicating a Device was removed from a DeviceProvider (Since: 1.4)

MessageTypePropertyNotify

Message indicating a Object property has changed (Since: 1.10)

MessageTypeStreamCollection

Message indicating a new StreamCollection is available (Since: 1.10)

MessageTypeStreamsSelected

Message indicating the active selection of GstStreams has changed (Since: 1.10)

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 Device was changed a DeviceProvider (Since: 1.16)

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.

PadFlags

data PadFlags Source #

Pad state flags

Constructors

PadFlagsFlushing

is pad flushing

PadFlagsEos

is pad in EOS state

PadFlagsBlocking

is pad currently blocking on a buffer or event

PadFlagsNeedParent

ensure that there is a parent object before calling into the pad callbacks.

PadFlagsNeedReconfigure

the pad should be reconfigured/renegotiated. The flag has to be unset manually after reconfiguration happened.

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.

PadFlagsAcceptIntersect

the default accept-caps handler will check it the caps intersect the query-caps result instead of checking for a subset. This is interesting for parsers that can accept incompletely specified caps.

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 with PadFlagsAcceptIntersect. (Since: 1.6)

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
will not fail because of hierarchy\/caps compatibility failures. If uncertain,
use the default checks ('GI.Gst.Flags.PadLinkCheckDefault') or the regular methods
for linking the pads.

Constructors

PadLinkCheckNothing

Don't check hierarchy or caps compatibility.

PadLinkCheckHierarchy

Check the pads have same parents/grandparents. Could be omitted if it is already known that the two elements that own the pads are in the same bin.

PadLinkCheckTemplateCaps

Check if the pads are compatible by using their template caps. This is much faster than gSTPADLINKCHECKCAPS, but would be unsafe e.g. if one pad has GST_CAPS_ANY.

PadLinkCheckCaps

Check if the pads are compatible by comparing the caps returned by padQueryCaps.

PadLinkCheckNoReconfigure

Disables pushing a reconfigure event when pads are linked.

PadLinkCheckDefault

The default checks done when linking pads (i.e. the ones used by padLink).

SeekFlags

data SeekFlags Source #

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

SeekFlagsFlush

SeekFlagsAccurate

accurate position is requested, this might be considerably slower for some formats.

SeekFlagsKeyUnit

seek to the nearest keyframe. This might be faster but less accurate.

SeekFlagsSegment

SeekFlagsTrickmode

when doing fast forward or fast reverse playback, allow elements to skip frames instead of generating all frames. (Since: 1.6)

SeekFlagsSkip

Deprecated backward compatibility flag, replaced by SeekFlagsTrickmode

SeekFlagsSnapBefore

go to a location before the requested position, if SeekFlagsKeyUnit this means the keyframe at or before the requested position the one at or before the seek target.

SeekFlagsSnapAfter

go to a location after the requested position, if SeekFlagsKeyUnit this means the keyframe at of after the requested position.

SeekFlagsSnapNearest

go to a position near the requested position, if SeekFlagsKeyUnit this means the keyframe closest to the requested position, if both keyframes are at an equal distance, behaves like SeekFlagsSnapBefore.

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)
