* GstAudioEncoder and subclass should cooperate as follows.
*
* ## Configuration
*
* * Initially, GstAudioEncoder calls @start when the encoder element
* is activated, which allows subclass to perform any global setup.
*
* * GstAudioEncoder calls @set_format to inform subclass of the format
* of input audio data that it is about to receive. Subclass should
* setup for encoding and configure various base class parameters
* appropriately, notably those directing desired input data handling.
* While unlikely, it might be called more than once, if changing input
* parameters require reconfiguration.
*
* * GstAudioEncoder calls @stop at end of all processing.

* As of configuration stage, and throughout processing, GstAudioEncoder
* maintains various parameters that provide required context,
* e.g. describing the format of input audio data.
* Conversely, subclass can and should configure these context parameters
* to inform base class of its expectation w.r.t. buffer handling.
*
* ## Data processing
*
* * Base class gathers input sample data (as directed by the context's
* frame_samples and frame_max) and provides this to subclass' @handle_frame.
* * If codec processing results in encoded data, subclass should call
2013-03-25 15:46:29 +00:00
* gst_audio_encoder_finish_frame() to have encoded data pushed
* downstream. Alternatively, it might also call
* gst_audio_encoder_finish_frame() (with a NULL buffer and some number of
* dropped samples) to indicate dropped (non-encoded) samples.
* * Just prior to actually pushing a buffer downstream,
* it is passed to @pre_push.
* * During the parsing process GstAudioEncoderClass will handle both
* srcpad and sinkpad events. Sink events will be passed to subclass
* if @event callback has been provided.
*
* ## Shutdown phase
*
* * GstAudioEncoder class calls @stop to inform the subclass that data
* parsing will be stopped.
*
* Subclass is responsible for providing pad template caps for
2013-12-20 21:54:39 +00:00
* source and sink pads. The pads need to be named "sink" and "src". It also
* needs to set the fixed caps on srcpad, when the format is ensured. This
* is typically when base class calls subclass' @set_format function, though

* it might be delayed until calling @gst_audio_encoder_finish_frame.
*
* In summary, above process should have subclass concentrating on
* codec data processing while leaving other matters to base class,
* such as most notably timestamp handling. While it may exert more control
* in this area (see e.g. @pre_push), it is very much not recommended.
*
* In particular, base class will either favor tracking upstream timestamps
* (at the possible expense of jitter) or aim to arrange for a perfect stream of
* output timestamps, depending on #GstAudioEncoder:perfect-timestamp.
* However, in the latter case, the input may not be so perfect or ideal, which
* is handled as follows. An input timestamp is compared with the expected
* timestamp as dictated by input sample stream and if the deviation is less

2011-03-09 11:18:56 +00:00
* Otherwise, it is considered a discontuinity and subsequent output timestamp
* is resynced to the new position after performing configured discontinuity
* processing. In the non-perfect-timestamp case, an upstream variation
* exceeding tolerance only leads to marking DISCONT on subsequent outgoing
2011-03-09 11:18:56 +00:00
* (while timestamps are adjusted to upstream regardless of variation).
* While DISCONT is also marked in the perfect-timestamp case, this one
* optionally (see #GstAudioEncoder:hard-resync)
* performs some additional steps, such as clipping of (early) input samples
* or draining all currently remaining input data, depending on the direction
* of the discontuinity.
*
* If perfect timestamps are arranged, it is also possible to request baseclass
* (usually set by subclass) to provide additional buffer metadata (in OFFSET
* and OFFSET_END) fields according to granule defined semantics currently
* needed by oggmux. Specifically, OFFSET is set to granulepos (= sample count
* including buffer) and OFFSET_END to corresponding timestamp (as determined
* by same sample count and sample rate).
*
* Things that subclass need to take care of:
*
* * Provide pad templates
* * Set source pad caps when appropriate
* * Inform base class of buffer processing needs using context's
* frame_samples and frame_bytes.
* * Set user-configurable properties to sane defaults for format and
* implementing codec at hand, e.g. those controlling timestamp behaviour
* and discontinuity processing.
* * Accept data in @handle_frame and provide encoded results to
2013-03-25 15:46:29 +00:00
* gst_audio_encoder_finish_frame().

* @buffer: (transfer full) (nullable): encoded data
* @samples: number of samples (per channel) represented by encoded data
*
* Collects encoded data and pushes encoded data downstream.
* Source pad caps must be set when this is called.
*
* If @samples < 0, then best estimate is all samples provided to encoder
* (subclass) so far. @buf may be NULL, in which case next number of @samples
* are considered discarded, e.g. as a result of discontinuous transmission,
* and a discontinuity is marked.
*
* Note that samples received in #GstAudioEncoderClass.handle_frame()
* may be invalidated by a call to this function.
*
* Returns: a #GstFlowReturn that should be escalated to caller (of caller)
