CapsIntersectMode

data CapsIntersectMode

Modes of caps intersection

gSTCAPSINTERSECTZIGZAG tries to preserve overall order of both caps by iterating on the caps' structures as the following matrix shows: > > caps1 > +------------- > | 1 2 4 7 >caps2 | 3 5 8 10 > | 6 9 11 12

Used when there is no explicit precedence of one caps over the other. e.g. tee's sink pad getcaps function, it will probe its src pad peers' for their caps and intersect them with this mode.

gSTCAPSINTERSECTFIRST is useful when an element wants to preserve another element's caps priority order when intersecting with its own caps. Example: If caps1 is [A, B, C] and caps2 is [E, B, D, A], the result would be [A, B], maintaining the first caps priority on the intersection.

DebugLevel

data 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.

Constructors

DebugLevelNone

No debugging level specified or desired. Used to deactivate debugging output.

DebugLevelError

Error messages are to be used only when an error occurred that stops the application from keeping working correctly. An examples is gst_element_error, which outputs a message with this priority. It does not mean that the application is terminating as with g_error.

DebugLevelWarning

Warning messages are to inform about abnormal behaviour that could lead to problems or weird behaviour later on. An example of this would be clocking issues ("your computer is pretty slow") or broken input data ("Can't synchronize to stream.")

DebugLevelFixme

Fixme messages are messages that indicate that something in the executed code path is not fully implemented or handled yet. Note that this does not replace proper error handling in any way, the purpose of this message is to make it easier to spot incomplete/unfinished pieces of code when reading the debug log.

DebugLevelInfo

Informational messages should be used to keep the developer updated about what is happening. Examples where this should be used are when a typefind function has successfully determined the type of the stream or when an mp3 plugin detects the format to be used. ("This file has mono sound.")

DebugLevelDebug

Debugging messages should be used when something common happens that is not the expected default behavior, or something that's useful to know but doesn't happen all the time (ie. per loop iteration or buffer processed or event handled). An example would be notifications about state changes or receiving/sending of events.

DebugLevelLog

Log messages are messages that are very common but might be useful to know. As a rule of thumb a pipeline that is running as expected should never output anything else but LOG messages whilst processing data. Use this log level to log recurring information in chain functions and loop functions, for example.

DebugLevelTrace

Tracing-related messages. Examples for this are referencing/dereferencing of objects.

DebugLevelMemdump

memory dump messages are used to log (small) chunks of data as memory dumps in the log. They will be displayed as hexdump with ASCII characters.

DebugLevelCount

The number of defined debugging levels.

EventType

data EventType

EventType lists the standard event types that can be sent in a pipeline.

The custom event types can be used for private messages between elements that can't be expressed using normal GStreamer buffer passing semantics. Custom events carry an arbitrary Structure. Specific custom events are distinguished by the name of the structure.

Constructors

EventTypeUnknown

unknown event.

EventTypeFlushStart

Start a flush operation. This event clears all data from the pipeline and unblock all streaming threads.

EventTypeFlushStop

Stop a flush operation. This event resets the running-time of the pipeline.

EventTypeStreamStart

Event to mark the start of a new stream. Sent before any other serialized event and only sent at the start of a new stream, not after flushing seeks.

EventTypeCaps

Caps event. Notify the pad of a new media type.

EventTypeSegment

A new media segment follows in the dataflow. The segment events contains information for clipping buffers and converting buffer timestamps to running-time and stream-time.

EventTypeStreamCollection

A new StreamCollection is available (Since 1.10)

EventTypeTag

A new set of metadata tags has been found in the stream.

EventTypeBuffersize

Notification of buffering requirements. Currently not used yet.

EventTypeSinkMessage

An event that sinks turn into a message. Used to send messages that should be emitted in sync with rendering.

EventTypeStreamGroupDone

Indicates that there is no more data for the stream group ID in the message. Sent before EOS in some instances and should be handled mostly the same. (Since 1.10)

EventTypeEos

End-Of-Stream. No more data is to be expected to follow without either a STREAM_START event, or a FLUSH_STOP and a SEGMENT event.

EventTypeToc

An event which indicates that a new table of contents (TOC) was found or updated.

EventTypeProtection

An event which indicates that new or updated encryption information has been found in the stream.

EventTypeSegmentDone

Marks the end of a segment playback.

EventTypeGap

Marks a gap in the datastream.

EventTypeQos

A quality message. Used to indicate to upstream elements that the downstream elements should adjust their processing rate.

EventTypeSeek

A request for a new playback position and rate.

EventTypeNavigation

Navigation events are usually used for communicating user requests, such as mouse or keyboard movements, to upstream elements.

EventTypeLatency

Notification of new latency adjustment. Sinks will use the latency information to adjust their synchronisation.

EventTypeStep

A request for stepping through the media. Sinks will usually execute the step operation.

EventTypeReconfigure

A request for upstream renegotiating caps and reconfiguring.

EventTypeTocSelect

A request for a new playback position based on TOC entry's UID.

EventTypeSelectStreams

A request to select one or more streams (Since 1.10)

EventTypeCustomUpstream

Upstream custom event

EventTypeCustomDownstream

Downstream custom event that travels in the data flow.

EventTypeCustomDownstreamOob

Custom out-of-band downstream event.

EventTypeCustomDownstreamSticky

Custom sticky downstream event.

EventTypeCustomBoth

Custom upstream or downstream event. In-band when travelling downstream.

PadProbeReturn

data PadProbeReturn

Different return values for the PadProbeCallback.

Constructors

PadProbeReturnDrop

drop data in data probes. For push mode this means that the data item is not sent downstream. For pull mode, it means that the data item is not passed upstream. In both cases, no other probes are called for this item and FlowReturnOk or True is returned to the caller.

PadProbeReturnOk

normal probe return value. This leaves the probe in place, and defers decisions about dropping or passing data to other probes, if any. If there are no other probes, the default behaviour for the probe type applies ('block' for blocking probes, and 'pass' for non-blocking probes).

PadProbeReturnRemove

remove this probe.

PadProbeReturnPass

pass the data item in the block probe and block on the next item.

PadProbeReturnHandled

Data has been handled in the probe and will not be forwarded further. For events and buffers this is the same behaviour as PadProbeReturnDrop (except that in this case you need to unref the buffer or event yourself). For queries it will also return True to the caller. The probe can also modify the FlowReturn value by using the GST_PAD_PROBE_INFO_FLOW_RETURN() accessor. Note that the resulting query must contain valid entries. Since: 1.6

State

data State

The possible states an element can be in. States can be changed using elementSetState and checked using elementGetState.

Constructors

StateVoidPending

no pending state.

StateNull

the NULL state or initial state of an element.

StateReady

the element is ready to go to PAUSED.

StatePaused

the element is PAUSED, it is ready to accept and process data. Sink elements however only accept one buffer and then block.

StatePlaying

the element is PLAYING, the Clock is running and the data is flowing.

StateChange

data StateChange

These are the different state changes an element goes through. StateNull &rArr; StatePlaying is called an upwards state change and StatePlaying &rArr; StateNull a downwards state change.

Constructors

StateChangeNullToReady

state change from NULL to READY. * The element must check if the resources it needs are available. Device sinks and -sources typically try to probe the device to constrain their caps. * The element opens the device (in case feature need to be probed).

StateChangeReadyToPaused

state change from READY to PAUSED. * The element pads are activated in order to receive data in PAUSED. Streaming threads are started. * Some elements might need to return StateChangeReturnAsync and complete the state change when they have enough information. It is a requirement for sinks to return StateChangeReturnAsync and complete the state change when they receive the first buffer or EventTypeEos (preroll). Sinks also block the dataflow when in PAUSED. * A pipeline resets the running_time to 0. * Live sources return StateChangeReturnNoPreroll and don't generate data.

StateChangePausedToPlaying

state change from PAUSED to PLAYING. * Most elements ignore this state change. * The pipeline selects a Clock and distributes this to all the children before setting them to PLAYING. This means that it is only allowed to synchronize on the Clock in the PLAYING state. * The pipeline uses the Clock and the running_time to calculate the base_time. The base_time is distributed to all children when performing the state change. * Sink elements stop blocking on the preroll buffer or event and start rendering the data. * Sinks can post MessageTypeEos in the PLAYING state. It is not allowed to post MessageTypeEos when not in the PLAYING state. * While streaming in PAUSED or PLAYING elements can create and remove sometimes pads. * Live sources start generating data and return StateChangeReturnSuccess.

StateChangePlayingToPaused

state change from PLAYING to PAUSED. * Most elements ignore this state change. * The pipeline calculates the running_time based on the last selected Clock and the base_time. It stores this information to continue playback when going back to the PLAYING state. * Sinks unblock any Clock wait calls. * When a sink does not have a pending buffer to play, it returns GST_STATE_CHANGE_ASYNC from this state change and completes the state change when it receives a new buffer or an EventTypeEos. * Any queued MessageTypeEos items are removed since they will be reposted when going back to the PLAYING state. The EOS messages are queued in Bin containers. * Live sources stop generating data and return StateChangeReturnNoPreroll.

StateChangePausedToReady

state change from PAUSED to READY. * Sinks unblock any waits in the preroll. * Elements unblock any waits on devices * Chain or get_range functions return FlowReturnFlushing. * The element pads are deactivated so that streaming becomes impossible and all streaming threads are stopped. * The sink forgets all negotiated formats * Elements remove all sometimes pads

StateChangeReadyToNull

state change from READY to NULL. * Elements close devices * Elements reset any internal state.

StateChangeNullToNull

state change from NULL to NULL. (Since 1.14)

StateChangeReadyToReady

state change from READY to READY, This might happen when going to PAUSED asynchronously failed, in that case elements should make sure they are in a proper, coherent READY state. (Since 1.14)

StateChangePausedToPaused

state change from PAUSED to PAUSED. This might happen when elements were in PLAYING state and 'lost state', they should make sure to go back to real 'PAUSED' state (prerolling for example). (Since 1.14)

StateChangePlayingToPlaying

state change from PLAYING to PLAYING. (Since 1.14)

This enumerating declares to which scope such a meta data field relates to. If it is e.g. TracerValueScopePad, then each of the log events may contain values for different GstPads.

Since: 1.8

Constructors
