    /// 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.
