* @short_description: Base class for sink elements
2009-11-27 14:39:37 +00:00
* @see_also: #GstBaseTransform, #GstBaseSrc
*
* #GstBaseSink is the base class for sink elements in GStreamer, such as
* xvimagesink or filesink. It is a layer on top of #GstElement that provides a
* simplified interface to plugin writers. #GstBaseSink 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 #GstElement or to set functions on pads, because the
* #GstBaseSink infrastructure should be sufficient.
*
* #GstBaseSink provides support for exactly one sink pad, which should be
* named "sink". A sink implementation (subclass of #GstBaseSink) should
* install a pad template in its class_init function, like so:
* |[<!-- language="C" -->
* static void
* my_element_class_init (GstMyElementClass *klass)
* {
* GstElementClass *gstelement_class = GST_ELEMENT_CLASS (klass);
2009-08-24 15:56:32 +00:00
*
* // sinktemplate should be a #GstStaticPadTemplate with direction
* // %GST_PAD_SINK and name "sink"
* gst_element_class_add_static_pad_template (gstelement_class, &amp;sinktemplate);
2012-09-26 14:26:48 +00:00
*
* gst_element_class_set_static_metadata (gstelement_class,
* "Sink name",
* "Sink",
* "My Sink element",
* "The author <my.sink@my.email>");
* }
2009-11-27 14:39:37 +00:00
* ]|
*
* #GstBaseSink will handle the prerolling correctly. This means that it will
* return %GST_STATE_CHANGE_ASYNC from a state change to PAUSED until the first
* buffer arrives in this element. The base class will call the
2009-11-27 14:39:37 +00:00
* #GstBaseSinkClass.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, #GstBaseSink will synchronise on the
2009-11-27 14:39:37 +00:00
* clock using the times returned from #GstBaseSinkClass.get_times(). If this
* function returns %GST_CLOCK_TIME_NONE for the start time, no synchronisation
2009-11-27 14:39:37 +00:00
* will be done. Synchronisation can be disabled entirely by setting the object
* #GstBaseSink:sync property to %FALSE.
*
2009-11-27 14:39:37 +00:00
* After synchronisation the virtual method #GstBaseSinkClass.render() will be
* called. Subclasses should minimally implement this method.
*
* Subclasses that synchronise on the clock in the #GstBaseSinkClass.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 gst_base_sink_wait_preroll() to perform the
* blocking wait.
*
* Upon receiving the EOS event in the PLAYING state, #GstBaseSink will wait
* for the clock to reach the time indicated by the stop time of the last
2009-11-27 14:39:37 +00:00
* #GstBaseSinkClass.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.
*
* #GstBaseSink will internally use the %GST_EVENT_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.
*
* #GstBaseSink 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.
*
2009-11-27 14:39:37 +00:00
* The #GstBaseSinkClass.set_caps() function will be called when the subclass
* should configure itself to process a specific media type.
*
* The #GstBaseSinkClass.start() and #GstBaseSinkClass.stop() virtual methods
* will be called when resources should be allocated. Any
2009-11-27 14:39:37 +00:00
* #GstBaseSinkClass.preroll(), #GstBaseSinkClass.render() and
* #GstBaseSinkClass.set_caps() function will be called between the
* #GstBaseSinkClass.start() and #GstBaseSinkClass.stop() calls.
*
* The #GstBaseSinkClass.event() virtual method will be called when an event is
* received by #GstBaseSink. Normally this method should only be overridden by
2009-11-27 14:39:37 +00:00
* very specific elements (such as file sinks) which need to handle the
* newsegment event specially.
*
* The #GstBaseSinkClass.unlock() method is called when the elements should
* unblock any blocking operations they perform in the
* #GstBaseSinkClass.render() method. This is mostly useful when the
* #GstBaseSinkClass.render() method performs a blocking write on a file
* descriptor, for example.
*
* The #GstBaseSink: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.
2009-11-27 14:39:37 +00:00
* This feature is disabled if sync is disabled, the
* #GstBaseSinkClass.get_times() method does not return a valid start time or
* max-lateness is set to -1 (the default).
* Subclasses can use gst_base_sink_set_max_lateness() to configure the
* max-lateness value.
*
2009-11-27 14:39:37 +00:00
* The #GstBaseSink: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 #GstBaseSink: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.

basesink: Fix clock synchronization running time in reverse playback In reverse playback, buffers have to be displayed at buffer.stop running time, otherwise a same set of buffer can't be displayed in the exact opposite order to forward playback. For example, seeking a video stream at 1fps with start=0, stop=5s, rate=1.0 will display the following buffers: b0.pts = 0s, b0.duration = 1s - at running time = 0s b1.pts = 1s, b1.duration = 1s - at running time = 1s b2.pts = 2s, b2.duration = 1s - at running time = 2s b3.pts = 3s, b3.duration = 1s - at running time = 3s b4.pts = 4s, b4.duration = 1s - at running time = 4s <wait at EOS for 1second> Now, playing that reverse with start=0, stop=5s, rate=1.0 has to display the following buffers: b0.pts = 4s, b0.duration = 1s - at running time = 0s b1.pts = 3s, b1.duration = 1s - at running time = 1s b2.pts = 2s, b2.duration = 1s - at running time = 2s b3.pts = 1s, b3.duration = 1s - at running time = 3s b4.pts = 0s, b4.duration = 1s - at running time = 4s <wait at EOS for 1second> With the previous code, it reproduced the following: b0.pts = 4s, b0.duration = 1s - at running time = 1s b1.pts = 3s, b1.duration = 1s - at running time = 2s b2.pts = 2s, b2.duration = 1s - at running time = 3s b3.pts = 1s, b3.duration = 1s - at running time = 4s b4.pts = 0s, b4.duration = 1s - at running time = 5s <NO WAIT AT EOS AND POST EOS RIGHT AWAY> This is being tested with the `validate.launch_pipeline.sink.reverse_playback_clock_waits.*` set of tests Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/450>

(pre_activate_switch, post_activate_switch): New stubs, things to do before and after switching activation modes on pads. (gst_pad_set_active): Take a boolean and not a mode, dispatch to the pad's activate function to choose which mode to activate. Shortcut on deactivation and call the right function directly. (gst_pad_activate_pull): New API, (de)activates a pad in pull mode. (gst_pad_activate_push): New API, same for push mode. (gst_pad_set_activate_function) (gst_pad_set_activatepull_function) (gst_pad_set_activatepush_function): Setters for new API. * gst/gstminiobject.c (gst_mini_object_new, gst_mini_object_free): Trace all miniobjects.

(gst_element_pads_activate): Simplified via use of fold and delegation of decisions to gstpad->activate. * gst/gstbus.c (gst_bus_source_finalize): Set the bus to NULL, help in debugging. * gst/gstbuffer.c (_gst_buffer_initialize): Ref the buffer type class once in init, like gstmessage. Didn't run into this issue but it seems correct. Don't initialize a trace, gstminiobject does that. * check/pipelines/simple_launch_lines.c (test_stop_from_app): New test, runs fakesrc ! fakesink, stopping on ::handoff via a message to the bus. (assert_live_count): New util function, uses alloc traces to check cleanup. * check/gst/gstghostpad.c (test_ghost_pads): More refcount checks. To be modified when unlink drops the internal pad.
