Struct gstreamer_rtp::RTPBaseDepayload
source · pub struct RTPBaseDepayload { /* private fields */ }Expand description
Provides a base class for RTP depayloaders
In order to handle RTP header extensions correctly if the
depayloader aggregates multiple RTP packet payloads into one output
buffer this class provides the function
RTPBaseDepayloadExt::set_aggregate_hdrext_enabled(). If the
aggregation is enabled the virtual functions
RTPBaseDepayload or
RTPBaseDepayload must tell the base class
what happens to the current RTP packet. By default the base class
assumes that the packet payload is used with the next output
buffer.
If the RTP packet will not be used with an output buffer
RTPBaseDepayloadExt::dropped() must be called. A typical
situation would be if we are waiting for a keyframe.
If the RTP packet will be used but not with the current output
buffer but with the next one RTPBaseDepayloadExt::delayed() must
be called. This may happen if the current RTP packet signals the
start of a new output buffer and the currently processed output
buffer will be pushed first. The undelay happens implicitly once
the current buffer has been pushed or
RTPBaseDepayloadExt::flush() has been called.
If RTPBaseDepayloadExt::flush() is called all RTP packets that
have not been dropped since the last output buffer are dropped,
e.g. if an output buffer is discarded due to malformed data. This
may or may not include the current RTP packet depending on the 2nd
parameter keep_current.
Be aware that in case RTPBaseDepayloadExt::push_list() is used
each buffer will see the same list of RTP header extensions.
This is an Abstract Base Class, you cannot instantiate it.
§Properties
§auto-header-extension
If enabled, the depayloader will automatically try to enable all the RTP header extensions provided in the sink caps, saving the application the need to handle these extensions manually using the GstRTPBaseDepayload::request-extension: signal.
Readable | Writeable
§extensions
A list of already enabled RTP header extensions. This may be useful for finding out which extensions are already enabled (with add-extension signal) and picking a non-conflicting ID for a new extension that needs to be added on top of the existing ones.
Note that the value returned by reading this property is not dynamically updated when the set of enabled extensions changes by any of existing action signals. Rather, it represents the current state at the time the property is read.
Dynamic updates of this property can be received by subscribing to its corresponding “notify” signal, i.e. “notify::extensions”.
Readable
§max-reorder
Max seqnum reorder before the sender is assumed to have restarted.
When max-reorder is set to 0 all reordered/duplicate packets are considered coming from a restarted sender.
Readable | Writeable
§source-info
Add RTP source information found in RTP header as meta to output buffer.
Readable | Writeable
§stats
Various depayloader statistics retrieved atomically (and are therefore synchroized with each other). This property return a GstStructure named application/x-rtp-depayload-stats containing the following fields relating to the last processed buffer and current state of the stream being depayloaded:
clock-rate:G_TYPE_UINT, clock-rate of the streamnpt-start:G_TYPE_UINT64, time of playback startnpt-stop:G_TYPE_UINT64, time of playback stopplay-speed:G_TYPE_DOUBLE, the playback speedplay-scale:G_TYPE_DOUBLE, the playback scalerunning-time-dts:G_TYPE_UINT64, the last running-time of the last DTSrunning-time-pts:G_TYPE_UINT64, the last running-time of the last PTSseqnum:G_TYPE_UINT, the last seen seqnumtimestamp:G_TYPE_UINT, the last seen RTP timestamp
Readable
Object
§name
Readable | Writeable | Construct
§parent
The parent of the object. Please note, that when changing the ‘parent’
property, we don’t emit GObject::notify and deep-notify
signals due to locking issues. In some cases one can use
GstBin::element-added or GstBin::element-removed signals on the parent to
achieve a similar effect.
Readable | Writeable
§Signals
§add-extension
Add ext as an extension for reading part of an RTP header extension from
incoming RTP packets.
Action
§clear-extensions
Clear all RTP header extensions used by this depayloader.
Action
§request-extension
The returned ext must be configured with the correct ext_id and with the
necessary attributes as required by the extension implementation.
Element
§no-more-pads
This signals that the element will not generate more dynamic pads. Note that this signal will usually be emitted from the context of the streaming thread.
§pad-added
a new GstPad has been added to the element. Note that this signal will
usually be emitted from the context of the streaming thread. Also keep in
mind that if you add new elements to the pipeline in the signal handler
you will need to set them to the desired target state with
[ElementExtManual::set_state()][crate::gst::prelude::ElementExtManual::set_state()] or [ElementExtManual::sync_state_with_parent()][crate::gst::prelude::ElementExtManual::sync_state_with_parent()].
§pad-removed
a GstPad has been removed from the element
Object
§deep-notify
The deep notify signal is used to be notified of property changes. It is typically attached to the toplevel bin to receive notifications from all the elements contained in that bin.

Such pads need to be released manually when unlinking.
