/// 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
/// [`push_buffer()`][Self::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", "max-buffers" and "max-time" properties control 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
/// [`end_of_stream()`][Self::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.
///
/// ## Properties
///
///
/// #### `block`
/// When max-bytes are queued and after the enough-data signal has been emitted,
/// block any further push-buffer calls until the amount of queued bytes drops
/// below the max-bytes limit.
///
/// Readable | Writeable
///
///
/// #### `caps`
/// The GstCaps that will negotiated downstream and will be put
/// on outgoing buffers.
///
/// Readable | Writeable
///
///
/// #### `current-level-buffers`
/// The number of currently queued buffers inside appsrc.
///
/// Readable
///
///
/// #### `current-level-bytes`
/// The number of currently queued bytes inside appsrc.
///
/// Readable
///
///
/// #### `current-level-time`
/// The amount of currently queued time inside appsrc.
///
/// Readable
///
///
/// #### `duration`
/// The total duration in nanoseconds of the data stream. If the total duration is known, it

///
/// Readable | Writeable
///
///
/// #### `emit-signals`
/// Make appsrc emit the "need-data", "enough-data" and "seek-data" signals.
/// This option is by default enabled for backwards compatibility reasons but
/// can disabled when needed because signal emission is expensive.
///
/// Readable | Writeable
///
///
/// #### `format`
/// The format to use for segment events. When the source is producing
/// timestamped buffers this property should be set to GST_FORMAT_TIME.
///
/// Readable | Writeable
///
///
/// #### `handle-segment-change`
/// When enabled, appsrc will check GstSegment in GstSample which was
/// pushed via [`AppSrc::push_sample()`][crate::AppSrc::push_sample()] or "push-sample" signal action.
/// If a GstSegment is changed, corresponding segment event will be followed
/// by next data flow.
///
/// FIXME: currently only GST_FORMAT_TIME format is supported and therefore

///
/// #### `is-live`
/// Instruct the source to behave like a live source. This includes that it

/// Readable | Writeable
///
///
/// #### `leaky-type`
/// When set to any other value than GST_APP_LEAKY_TYPE_NONE then the appsrc

/// full. The selected type defines whether to drop the oldest or new
/// buffers.

///
///
/// #### `push-buffer`
/// Adds a buffer to the queue of buffers that the appsrc element will

///
/// This function does not take ownership of the buffer, but it takes a

///
/// #### `push-sample`
/// Extract a buffer from the provided sample and adds the extracted buffer
/// to the queue of buffers that the appsrc element will
/// push to its source pad. This function set the appsrc caps based on the caps
/// in the sample and reset the caps if they change.
