+<!-- file * -->
+<!-- struct AppSink -->
+Appsink is a sink plugin that supports many different methods for making
+the application get a handle on the GStreamer data in a pipeline. Unlike
+most GStreamer elements, Appsink provides external API functions.
+
+appsink can be used by linking to the gstappsink.h header file to access the
+methods or by using the appsink action signals and properties.
+
+The normal way of retrieving samples from appsink is by using the
+`AppSink::pull_sample` and `AppSink::pull_preroll` methods.
+These methods block until a sample becomes available in the sink or when the
+sink is shut down or reaches EOS. There are also timed variants of these
+methods, `AppSink::try_pull_sample` and `AppSink::try_pull_preroll`,
+which accept a timeout parameter to limit the amount of time to wait.
+
+Appsink will internally use a queue to collect buffers from the streaming
+thread. If the application is not pulling samples fast enough, this queue
+will consume a lot of memory over time. The "max-buffers" property can be
+used to limit the queue size. The "drop" property controls whether the
+streaming thread blocks or if older buffers are dropped when the maximum
+queue size is reached. Note that blocking the streaming thread can negatively
+affect real-time performance and should be avoided.
+
+If a blocking behaviour is not desirable, setting the "emit-signals" property
+to `true` will make appsink emit the "new-sample" and "new-preroll" signals
+when a sample can be pulled without blocking.
+
+The "caps" property on appsink can be used to control the formats that
+appsink can receive. This property can contain non-fixed caps, the format of
+the pulled samples can be obtained by getting the sample caps.
+
+If one of the pull-preroll or pull-sample methods return `None`, the appsink
+is stopped or in the EOS state. You can check for the EOS state with the
+"eos" property or with the `AppSink::is_eos` method.
+
+The eos signal can also be used to be informed when the EOS state is reached
+to avoid polling.

+<!-- struct AppSrc -->
+The appsrc element can be used by applications to insert data into a
+GStreamer pipeline. Unlike most GStreamer elements, appsrc provides
+external API functions.
+
+appsrc can be used by linking with the libgstapp library to access the
+methods directly or by using the appsrc action signals.
+
+Before operating appsrc, the caps property must be set to fixed caps
+describing the format of the data that will be pushed with appsrc. An
+exception to this is when pushing buffers with unknown caps, in which case no
+caps should be set. This is typically true of file-like sources that push raw
+byte buffers. If you don't want to explicitly set the caps, you can use
+gst_app_src_push_sample. This method gets the caps associated with the
+sample and sets them on the appsrc replacing any previously set caps (if
+different from sample's caps).
+
+The main way of handing data to the appsrc element is by calling the
+`AppSrc::push_buffer` method or by emitting the push-buffer action signal.
+This will put the buffer onto a queue from which appsrc will read from in its
+streaming thread. It is important to note that data transport will not happen
+from the thread that performed the push-buffer call.
+
+The "max-bytes" property controls how much data can be queued in appsrc
+before appsrc considers the queue full. A filled internal queue will always
+signal the "enough-data" signal, which signals the application that it should
+stop pushing data into appsrc. The "block" property will cause appsrc to
+block the push-buffer method until free data becomes available again.
+
+When the internal queue is running out of data, the "need-data" signal is
+emitted, which signals the application that it should start pushing more data
+into appsrc.
+
+In addition to the "need-data" and "enough-data" signals, appsrc can emit the
+"seek-data" signal when the "stream-mode" property is set to "seekable" or
+"random-access". The signal argument will contain the new desired position in
+the stream expressed in the unit set with the "format" property. After
+receiving the seek-data signal, the application should push-buffers from the
+new position.
+
+These signals allow the application to operate the appsrc in two different
+ways:
+
+The push mode, in which the application repeatedly calls the push-buffer/push-sample
+method with a new buffer/sample. Optionally, the queue size in the appsrc
+can be controlled with the enough-data and need-data signals by respectively
+stopping/starting the push-buffer/push-sample calls. This is a typical
+mode of operation for the stream-type "stream" and "seekable". Use this
+mode when implementing various network protocols or hardware devices.
+
+The pull mode, in which the need-data signal triggers the next push-buffer call.
+This mode is typically used in the "random-access" stream-type. Use this
+mode for file access or other randomly accessible sources. In this mode, a
+buffer of exactly the amount of bytes given by the need-data signal should be
+pushed into appsrc.
+
+In all modes, the size property on appsrc should contain the total stream
+size in bytes. Setting this property is mandatory in the random-access mode.
+For the stream and seekable modes, setting this property is optional but
+recommended.
+
+When the application has finished pushing data into appsrc, it should call
+`AppSrc::end_of_stream` or emit the end-of-stream action signal. After
+this call, no more buffers can be pushed into appsrc until a flushing seek
+occurs or the state of the appsrc has gone through READY.

+GstTestClock is an implementation of `gst::Clock` which has different
+behaviour compared to `gst::SystemClock`. Time for `gst::SystemClock` advances
+according to the system time, while time for `TestClock` changes only
+when `TestClock::set_time` or `TestClock::advance_time` are
+called. `TestClock` provides unit tests with the possibility to
+precisely advance the time in a deterministic manner, independent of the
+system time or any other external factors.
+
+## Advancing the time of a `TestClock`
+
+
+```C
+  #include <gst/gst.h>
+  #include <gst/check/gsttestclock.h>
+
+  GstClock *clock;
+  GstTestClock *test_clock;
+
+  clock = gst_test_clock_new ();
+  test_clock = GST_TEST_CLOCK (clock);
+  GST_INFO ("Time: %" GST_TIME_FORMAT, GST_TIME_ARGS (gst_clock_get_time (clock)));
+  gst_test_clock_advance_time ( test_clock, 1 * GST_SECOND);
+  GST_INFO ("Time: %" GST_TIME_FORMAT, GST_TIME_ARGS (gst_clock_get_time (clock)));

+  GST_INFO ("Time: %" GST_TIME_FORMAT, GST_TIME_ARGS (gst_clock_get_time (clock)));
+  ...
+```
+
+`gst::Clock` allows for setting up single shot or periodic clock notifications
+as well as waiting for these notifications synchronously (using
+`gst::Clock::id_wait`) or asynchronously (using `gst::Clock::id_wait_async` or
+`gst::Clock::id_wait_async`). This is used by many GStreamer elements,
+among them `GstBaseSrc` and `GstBaseSink`.
+
+`TestClock` keeps track of these clock notifications. By calling
+`TestClock::wait_for_next_pending_id` or
+`TestClock::wait_for_multiple_pending_ids` a unit tests may wait for the
+next one or several clock notifications to be requested. Additionally unit
+tests may release blocked waits in a controlled fashion by calling
+`TestClock::process_next_clock_id`. This way a unit test can control the
+inaccuracy (jitter) of clock notifications, since the test can decide to
+release blocked waits when the clock time has advanced exactly to, or past,
+the requested clock notification time.
+
+There are also interfaces for determining if a notification belongs to a
+`TestClock` or not, as well as getting the number of requested clock
+notifications so far.
+
+N.B.: When a unit test waits for a certain amount of clock notifications to
+be requested in `TestClock::wait_for_next_pending_id` or
+`TestClock::wait_for_multiple_pending_ids` then these functions may block
+for a long time. If they block forever then the expected clock notifications
+were never requested from `TestClock`, and so the assumptions in the code
+of the unit test are wrong. The unit test case runner in gstcheck is
+expected to catch these cases either by the default test case timeout or the
+one set for the unit test by calling tcase_set_timeout\(\).
+
+The sample code below assumes that the element under test will delay a
+buffer pushed on the source pad by some latency until it arrives on the sink
+pad. Moreover it is assumed that the element will at some point call
+`gst::Clock::id_wait` to synchronously wait for a specific time. The first
+buffer sent will arrive exactly on time only delayed by the latency. The
+second buffer will arrive a little late (7ms) due to simulated jitter in the
+clock notification.

+`NetClientClock` implements a custom `gst::Clock` that synchronizes its time
+to a remote time provider such as `NetTimeProvider`. `NtpClock`
+implements a `gst::Clock` that synchronizes its time to a remote NTPv4 server.
+
+A new clock is created with `NetClientClock::new` or
+`NtpClock::new`, which takes the address and port of the remote time
+provider along with a name and an initial time.
+
+This clock will poll the time provider and will update its calibration
+parameters based on the local and remote observations.
+
+The "round-trip" property limits the maximum round trip packets can take.
+
+Various parameters of the clock can be configured with the parent `gst::Clock`
+"timeout", "window-size" and "window-threshold" object properties.
+
+A `NetClientClock` and `NtpClock` is typically set on a `gst::Pipeline` with
+`gst::Pipeline::use_clock`.
+
+If you set a `gst::Bus` on the clock via the "bus" object property, it will
+send `gst::MessageType::Element` messages with an attached `gst::Structure` containing
+statistics about clock accuracy and network traffic.

+GstPtpClock implements a PTP (IEEE1588:2008) ordinary clock in slave-only
+mode, that allows a GStreamer pipeline to synchronize to a PTP network
+clock in some specific domain.
+
+The PTP subsystem can be initialized with `gst_ptp_init`, which then starts
+a helper process to do the actual communication via the PTP ports. This is
+required as PTP listens on ports < 1024 and thus requires special
+privileges. Once this helper process is started, the main process will
+synchronize to all PTP domains that are detected on the selected
+interfaces.
+
+`PtpClock::new` then allows to create a GstClock that provides the PTP
+time from a master clock inside a specific PTP domain. This clock will only
+return valid timestamps once the timestamps in the PTP domain are known. To
+check this, you can use `gst::ClockExt::wait_for_sync`, the GstClock::synced
+signal and `gst::ClockExt::is_synced`.
+
+To gather statistics about the PTP clock synchronization,
+`gst_ptp_statistics_callback_add` can be used. This gives the application
+the possibility to collect all kinds of statistics from the clock
+synchronization.

+
+The `DiscovererStreamInfo` represents the topology of the stream. Siblings
+can be iterated over with `DiscovererStreamInfoExt::get_next` and
+`DiscovererStreamInfoExt::get_previous`. Children (sub-streams) of a
+stream can be accessed using the `DiscovererContainerInfo` API.
+
+As a simple example, if you run `Discoverer` on an AVI file with one audio
+and one video stream, you will get a `DiscovererContainerInfo`
+corresponding to the AVI container, which in turn will have a
+`DiscovererAudioInfo` sub-stream and a `DiscovererVideoInfo` sub-stream
+for the audio and video streams respectively.

+<!-- impl RTSPUrl::fn decode_path_components -->
+Splits the path of `self` on '/' boundaries, decoding the resulting components,
+
+The decoding performed by this routine is "URI decoding", as defined in RFC
+3986, commonly known as percent-decoding. For example, a string "foo\%2fbar"
+will decode to "foo/bar" -- the \%2f being replaced by the corresponding byte
+with hex value 0x2f. Note that there is no guarantee that the resulting byte
+sequence is valid in any given encoding. As a special case, \%00 is not
+unescaped to NUL, as that would prematurely terminate the string.
+
+Also note that since paths usually start with a slash, the first component
+will usually be the empty string.
+
+# Returns
+
+`None`-terminated array of URL components. Free with
+`g_strfreev` when no longer needed.
+<!-- impl RTSPUrl::fn free -->
+Free the memory used by `self`.
+<!-- impl RTSPUrl::fn get_port -->
+Get the port number of `self`.
+## `port`
+location to hold the port
+
+# Returns
+
+`RTSPResult::Ok`.
+<!-- impl RTSPUrl::fn get_request_uri -->
+Get a newly allocated string describing the request URI for `self`.
+
+# Returns
+
+a string with the request URI. `g_free` after usage.
+<!-- impl RTSPUrl::fn get_request_uri_with_control -->
+Get a newly allocated string describing the request URI for `self`
+combined with the control path for `control_path`
+
+Feature: `v1_18`
+
+## `control_path`
+an RTSP aggregate control path
+
+# Returns
+
+a string with the request URI combined with the control path.
+`g_free` after usage.
+<!-- impl RTSPUrl::fn set_port -->
+Set the port number in `self` to `port`.
+## `port`
+the port
+
+# Returns
+
+`RTSPResult::Ok`.
+<!-- impl RTSPUrl::fn parse -->
+Parse the RTSP `urlstr` into a newly allocated `RTSPUrl`. Free after usage
+with `RTSPUrl::free`.
+## `urlstr`
+the url string to parse
+## `url`
+location to hold the result.
+
+# Returns
+
+a `RTSPResult`.

-// In this example, 2D graphics operation and text rendering will happen
