[−][src]Struct gstreamer_base::BaseSink
BaseSink
is the base class for sink elements in GStreamer, such as
xvimagesink or filesink. It is a layer on top of gst::Element
that provides a
simplified interface to plugin writers. BaseSink
handles many details
for you, for example: preroll, clock synchronization, state changes,
activation in push or pull mode, and queries.
In most cases, when writing sink elements, there is no need to implement
class methods from gst::Element
or to set functions on pads, because the
BaseSink
infrastructure should be sufficient.
BaseSink
provides support for exactly one sink pad, which should be
named "sink". A sink implementation (subclass of BaseSink
) should
install a pad template in its class_init function, like so:
static void
my_element_class_init (GstMyElementClass *klass)
{
GstElementClass *gstelement_class = GST_ELEMENT_CLASS (klass);
// sinktemplate should be a #GstStaticPadTemplate with direction
// %GST_PAD_SINK and name "sink"
gst_element_class_add_static_pad_template (gstelement_class, &sinktemplate);
gst_element_class_set_static_metadata (gstelement_class,
"Sink name",
"Sink",
"My Sink element",
"The author <my.sink@my.email>");
}
BaseSink
will handle the prerolling correctly. This means that it will
return gst::StateChangeReturn::Async
from a state change to PAUSED until the first
buffer arrives in this element. The base class will call the
BaseSinkClass.preroll
() vmethod with this preroll buffer and will then
commit the state change to the next asynchronously pending state.
When the element is set to PLAYING, BaseSink
will synchronise on the
clock using the times returned from BaseSinkClass.get_times
(). If this
function returns GST_CLOCK_TIME_NONE
for the start time, no synchronisation
will be done. Synchronisation can be disabled entirely by setting the object
BaseSink:sync
property to false
.
After synchronisation the virtual method BaseSinkClass.render
() will be
called. Subclasses should minimally implement this method.
Subclasses that synchronise on the clock in the BaseSinkClass.render
()
method are supported as well. These classes typically receive a buffer in
the render method and can then potentially block on the clock while
rendering. A typical example is an audiosink.
These subclasses can use BaseSink::wait_preroll
to perform the
blocking wait.
Upon receiving the EOS event in the PLAYING state, BaseSink
will wait
for the clock to reach the time indicated by the stop time of the last
BaseSinkClass.get_times
() call before posting an EOS message. When the
element receives EOS in PAUSED, preroll completes, the event is queued and an
EOS message is posted when going to PLAYING.
BaseSink
will internally use the gst::EventType::Segment
events to schedule
synchronisation and clipping of buffers. Buffers that fall completely outside
of the current segment are dropped. Buffers that fall partially in the
segment are rendered (and prerolled). Subclasses should do any subbuffer
clipping themselves when needed.
BaseSink
will by default report the current playback position in
gst::Format::Time
based on the current clock time and segment information.
If no clock has been set on the element, the query will be forwarded
upstream.
The BaseSinkClass.set_caps
() function will be called when the subclass
should configure itself to process a specific media type.
The BaseSinkClass.start
() and BaseSinkClass.stop
() virtual methods
will be called when resources should be allocated. Any
BaseSinkClass.preroll
(), BaseSinkClass.render
() and
BaseSinkClass.set_caps
() function will be called between the
BaseSinkClass.start
() and BaseSinkClass.stop
() calls.
The BaseSinkClass.event
() virtual method will be called when an event is
received by BaseSink
. Normally this method should only be overridden by
very specific elements (such as file sinks) which need to handle the
newsegment event specially.
The BaseSinkClass.unlock
() method is called when the elements should
unblock any blocking operations they perform in the
BaseSinkClass.render
() method. This is mostly useful when the
BaseSinkClass.render
() method performs a blocking write on a file
descriptor, for example.
The BaseSink:max-lateness
property affects how the sink deals with
buffers that arrive too late in the sink. A buffer arrives too late in the
sink when the presentation time (as a combination of the last segment, buffer
timestamp and element base_time) plus the duration is before the current
time of the clock.
If the frame is later than max-lateness, the sink will drop the buffer
without calling the render method.
This feature is disabled if sync is disabled, the
BaseSinkClass.get_times
() method does not return a valid start time or
max-lateness is set to -1 (the default).
Subclasses can use BaseSinkExt::set_max_lateness
to configure the
max-lateness value.
The BaseSink:qos
property will enable the quality-of-service features of
the basesink which gather statistics about the real-time performance of the
clock synchronisation. For each buffer received in the sink, statistics are
gathered and a QOS event is sent upstream with these numbers. This
information can then be used by upstream elements to reduce their processing
rate, for example.
The BaseSink:async
property can be used to instruct the sink to never
perform an ASYNC state change. This feature is mostly usable when dealing
with non-synchronized streams or sparse streams.
