'GI.GstBase.Objects.BaseSink.BaseSink' is the base class for sink elements in GStreamer, such as
xvimagesink or filesink. It is a layer on top of 'GI.Gst.Objects.Element.Element' that provides a
simplified interface to plugin writers. 'GI.GstBase.Objects.BaseSink.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 'GI.Gst.Objects.Element.Element' or to set functions on pads, because the
'GI.GstBase.Objects.BaseSink.BaseSink' infrastructure should be sufficient.

'GI.GstBase.Objects.BaseSink.BaseSink' provides support for exactly one sink pad, which should be
named \"sink\". A sink implementation (subclass of 'GI.GstBase.Objects.BaseSink.BaseSink') should
install a pad template in its class_init function, like so:

=== /C code/
>
>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>");
>}


'GI.GstBase.Objects.BaseSink.BaseSink' will handle the prerolling correctly. This means that it will
return 'GI.Gst.Enums.StateChangeReturnAsync' from a state change to PAUSED until the first
buffer arrives in this element. The base class will call the
'GI.GstBase.Structs.BaseSinkClass.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, 'GI.GstBase.Objects.BaseSink.BaseSink' will synchronise on the
clock using the times returned from 'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/get_times/@(). If this
function returns 'GI.Gst.Constants.CLOCK_TIME_NONE' for the start time, no synchronisation
will be done. Synchronisation can be disabled entirely by setting the object
'GI.GstBase.Objects.BaseSink.BaseSink':@/sync/@ property to 'False'.

After synchronisation the virtual method 'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/render/@() will be
called. Subclasses should minimally implement this method.

Subclasses that synchronise on the clock in the 'GI.GstBase.Structs.BaseSinkClass.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 'GI.GstBase.Objects.BaseSink.baseSinkWaitPreroll' to perform the
blocking wait.

Upon receiving the EOS event in the PLAYING state, 'GI.GstBase.Objects.BaseSink.BaseSink' will wait
for the clock to reach the time indicated by the stop time of the last
'GI.GstBase.Structs.BaseSinkClass.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.

'GI.GstBase.Objects.BaseSink.BaseSink' will internally use the 'GI.Gst.Enums.EventTypeSegment' 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.

'GI.GstBase.Objects.BaseSink.BaseSink' will by default report the current playback position in
'GI.Gst.Enums.FormatTime' 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 'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/set_caps/@() function will be called when the subclass
should configure itself to process a specific media type.

The 'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/start/@() and 'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/stop/@() virtual methods
will be called when resources should be allocated. Any
'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/preroll/@(), 'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/render/@() and
'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/set_caps/@() function will be called between the
'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/start/@() and 'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/stop/@() calls.

The 'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/event/@() virtual method will be called when an event is
received by 'GI.GstBase.Objects.BaseSink.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 'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/unlock/@() method is called when the elements should
unblock any blocking operations they perform in the
'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/render/@() method. This is mostly useful when the
'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/render/@() method performs a blocking write on a file
descriptor, for example.

The 'GI.GstBase.Objects.BaseSink.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
'GI.GstBase.Structs.BaseSinkClass.BaseSinkClass'.@/get_times/@() method does not return a valid start time or
max-lateness is set to -1 (the default).
Subclasses can use 'GI.GstBase.Objects.BaseSink.baseSinkSetMaxLateness' to configure the
max-lateness value.

The 'GI.GstBase.Objects.BaseSink.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 'GI.GstBase.Objects.BaseSink.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.
