a data processing error that may be fatal for the current "data unit" but
need not prevent subsequent decoding.  Such errors are counted and if there
are too many, as configured in the context's max_errors, the pipeline will
post an error message and the application will be requested to stop further
media processing.  Otherwise, it is considered a "glitch" and only a warning
is logged. In either case, @ret is set to the proper value to

raw audio samples.

GstAudioDecoder and subclass should cooperate as follows.
&lt;orderedlist&gt;
&lt;listitem&gt;
  &lt;itemizedlist&gt;&lt;title&gt;Configuration&lt;/title&gt;
  &lt;listitem&gt;&lt;para&gt;
    Initially, GstAudioDecoder calls @start when the decoder element
    is activated, which allows subclass to perform any global setup.
    Base class (context) parameters can already be set according to subclass
    capabilities (or possibly upon receive more information in subsequent
    @set_format).
  &lt;/para&gt;&lt;/listitem&gt;
  &lt;listitem&gt;&lt;para&gt;
    GstAudioDecoder calls @set_format to inform subclass of the format
    of input audio data that it is about to receive.
    While unlikely, it might be called more than once, if changing input
    parameters require reconfiguration.
  &lt;/para&gt;&lt;/listitem&gt;
  &lt;listitem&gt;&lt;para&gt;
    GstAudioDecoder calls @stop at end of all processing.
  &lt;/para&gt;&lt;/listitem&gt;
  &lt;/itemizedlist&gt;
&lt;/listitem&gt;
As of configuration stage, and throughout processing, GstAudioDecoder
provides various (context) parameters, e.g. describing the format of
output audio data (valid when output caps have been set) or current parsing state.
Conversely, subclass can and should configure context to inform
base class of its expectation w.r.t. buffer handling.
&lt;listitem&gt;
  &lt;itemizedlist&gt;
  &lt;title&gt;Data processing&lt;/title&gt;
    &lt;listitem&gt;&lt;para&gt;
      Base class gathers input data, and optionally allows subclass
      to parse this into subsequently manageable (as defined by subclass)
      chunks.  Such chunks are subsequently referred to as 'frames',
      though they may or may not correspond to 1 (or more) audio format frame.
    &lt;/para&gt;&lt;/listitem&gt;
    &lt;listitem&gt;&lt;para&gt;
      Input frame is provided to subclass' @handle_frame.
    &lt;/para&gt;&lt;/listitem&gt;
    &lt;listitem&gt;&lt;para&gt;
      If codec processing results in decoded data, subclass should call
      @gst_audio_decoder_finish_frame to have decoded data pushed
      downstream.
    &lt;/para&gt;&lt;/listitem&gt;
    &lt;listitem&gt;&lt;para&gt;
      Just prior to actually pushing a buffer downstream,
      it is passed to @pre_push.  Subclass should either use this callback
      to arrange for additional downstream pushing or otherwise ensure such
      custom pushing occurs after at least a method call has finished since
      setting src pad caps.
    &lt;/para&gt;&lt;/listitem&gt;
    &lt;listitem&gt;&lt;para&gt;
      During the parsing process GstAudioDecoderClass will handle both
      srcpad and sinkpad events. Sink events will be passed to subclass
      if @event callback has been provided.
    &lt;/para&gt;&lt;/listitem&gt;
  &lt;/itemizedlist&gt;
&lt;/listitem&gt;
&lt;listitem&gt;
  &lt;itemizedlist&gt;&lt;title&gt;Shutdown phase&lt;/title&gt;
  &lt;listitem&gt;&lt;para&gt;
    GstAudioDecoder class calls @stop to inform the subclass that data
    parsing will be stopped.
  &lt;/para&gt;&lt;/listitem&gt;
  &lt;/itemizedlist&gt;
&lt;/listitem&gt;
&lt;/orderedlist&gt;

Subclass is responsible for providing pad template caps for
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_decoder_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 try to arrange for perfect output timestamps
as much as possible while tracking upstream timestamps.
To this end, if deviation between the next ideal expected perfect timestamp
and upstream exceeds #GstAudioDecoder:tolerance, then resync to upstream
occurs (which would happen always if the tolerance mechanism is disabled).

In non-live pipelines, baseclass can also (configurably) arrange for
output buffer aggregation which may help to redue large(r) numbers of
small(er) buffers being pushed and processed downstream.

On the other hand, it should be noted that baseclass only provides limited
seeking support (upon explicit subclass request), as full-fledged support
should rather be left to upstream demuxer, parser or alike.  This simple
approach caters for seeking and duration reporting using estimated input
bitrates.

Things that subclass need to take care of:
&lt;itemizedlist&gt;
  &lt;listitem&gt;&lt;para&gt;Provide pad templates&lt;/para&gt;&lt;/listitem&gt;
  &lt;listitem&gt;&lt;para&gt;
     Set source pad caps when appropriate
  &lt;/para&gt;&lt;/listitem&gt;
  &lt;listitem&gt;&lt;para&gt;
     Set user-configurable properties to sane defaults for format and
     implementing codec at hand, and convey some subclass capabilities and
     expectations in context.
  &lt;/para&gt;&lt;/listitem&gt;
  &lt;listitem&gt;&lt;para&gt;
     Accept data in @handle_frame and provide encoded results to
     @gst_audio_decoder_finish_frame.  If it is prepared to perform
     PLC, it should also accept NULL data in @handle_frame and provide for
     data for indicated duration.
  &lt;/para&gt;&lt;/listitem&gt;

           filename="gstaudioencoder.c"
           line="22">This base class is for audio encoders turning raw audio samples into
encoded audio data.

GstAudioEncoder and subclass should cooperate as follows.
&lt;orderedlist&gt;
&lt;listitem&gt;
  &lt;itemizedlist&gt;&lt;title&gt;Configuration&lt;/title&gt;
  &lt;listitem&gt;&lt;para&gt;
    Initially, GstAudioEncoder calls @start when the encoder element
    is activated, which allows subclass to perform any global setup.
  &lt;/para&gt;&lt;/listitem&gt;
  &lt;listitem&gt;&lt;para&gt;
    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.
  &lt;/para&gt;&lt;/listitem&gt;
  &lt;listitem&gt;&lt;para&gt;
    GstAudioEncoder calls @stop at end of all processing.
  &lt;/para&gt;&lt;/listitem&gt;
  &lt;/itemizedlist&gt;
&lt;/listitem&gt;
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.
&lt;listitem&gt;
  &lt;itemizedlist&gt;
  &lt;title&gt;Data processing&lt;/title&gt;
    &lt;listitem&gt;&lt;para&gt;
      Base class gathers input sample data (as directed by the context's
      frame_samples and frame_max) and provides this to subclass' @handle_frame.
    &lt;/para&gt;&lt;/listitem&gt;
    &lt;listitem&gt;&lt;para&gt;
      If codec processing results in encoded data, subclass should call
      @gst_audio_encoder_finish_frame to have encoded data pushed
      downstream.  Alternatively, it might also call to indicate dropped
      (non-encoded) samples.
    &lt;/para&gt;&lt;/listitem&gt;
    &lt;listitem&gt;&lt;para&gt;
      Just prior to actually pushing a buffer downstream,
      it is passed to @pre_push.
    &lt;/para&gt;&lt;/listitem&gt;
    &lt;listitem&gt;&lt;para&gt;
      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.
    &lt;/para&gt;&lt;/listitem&gt;
  &lt;/itemizedlist&gt;
&lt;/listitem&gt;
&lt;listitem&gt;
  &lt;itemizedlist&gt;&lt;title&gt;Shutdown phase&lt;/title&gt;
  &lt;listitem&gt;&lt;para&gt;
    GstAudioEncoder class calls @stop to inform the subclass that data
    parsing will be stopped.
  &lt;/para&gt;&lt;/listitem&gt;
  &lt;/itemizedlist&gt;
&lt;/listitem&gt;
&lt;/orderedlist&gt;

Subclass is responsible for providing pad template caps for
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
than #GstAudioEncoder:tolerance, the deviation is discarded.
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
(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:
&lt;itemizedlist&gt;
  &lt;listitem&gt;&lt;para&gt;Provide pad templates&lt;/para&gt;&lt;/listitem&gt;
  &lt;listitem&gt;&lt;para&gt;
     Set source pad caps when appropriate
  &lt;/para&gt;&lt;/listitem&gt;
  &lt;listitem&gt;&lt;para&gt;
     Inform base class of buffer processing needs using context's
     frame_samples and frame_bytes.
  &lt;/para&gt;&lt;/listitem&gt;
  &lt;listitem&gt;&lt;para&gt;
     Set user-configurable properties to sane defaults for format and
     implementing codec at hand, e.g. those controlling timestamp behaviour
     and discontinuity processing.
  &lt;/para&gt;&lt;/listitem&gt;
  &lt;listitem&gt;&lt;para&gt;
     Accept data in @handle_frame and provide encoded results to
     @gst_audio_encoder_finish_frame.
  &lt;/para&gt;&lt;/listitem&gt;

           line="22">#GstAudioFilter is a #GstBaseTransform&lt;!-- --&gt;-derived base class for simple audio
filters, ie. those that output the same format that they get as input.

#GstAudioFilter will parse the input format for you (with error checking)
before calling your setup function. Also, elements deriving from
#GstAudioFilter may use gst_audio_filter_class_add_pad_templates() from
their base_init function to easily configure the set of caps/formats that
the element is able to handle.

Derived classes should override the #GstAudioFilterClass.setup() and
#GstBaseTransformClass.transform_ip() and/or
#GstBaseTransformClass.transform()
virtual functions in their class_init function.

All scheduling of samples and timestamps is done in this base class
together with #GstBaseAudioSink using a default implementation of a
#GstRingBuffer that uses threads.

  &lt;varlistentry&gt;
    &lt;term&gt;delay()&lt;/term&gt;
    &lt;listitem&gt;&lt;para&gt;Get the number of samples in the device but not yet read.
    &lt;/para&gt;&lt;/listitem&gt;

    &lt;term&gt;unprepare()&lt;/term&gt;

  &lt;varlistentry&gt;
    &lt;term&gt;close()&lt;/term&gt;
    &lt;listitem&gt;&lt;para&gt;Close the device.&lt;/para&gt;&lt;/listitem&gt;
  &lt;/varlistentry&gt;
&lt;/variablelist&gt;

All scheduling of samples and timestamps is done in this base class
together with #GstBaseAudioSrc using a default implementation of a
#GstRingBuffer that uses threads.

This object is the base class for audio ringbuffers used by the base
audio source and sink classes.
&lt;/para&gt;
&lt;para&gt;
The ringbuffer abstracts a circular buffer of data. One reader and
one writer can operate on the data from different threads in a lockfree
manner. The base class is sufficiently flexible to be used as an
abstraction for DMA based ringbuffers as well as a pure software
implementations.
&lt;/para&gt;

@in_samples and @out_samples define the rate conversion to perform on the
samples in @data. For negative rates, @out_samples must be negative and
@in_samples positive.

When @out_samples is positive, the first sample will be written at position @sample
in the ringbuffer. When @out_samples is negative, the last sample will be written to
@sample in reverse order.

@out_samples does not need to be a multiple of the segment size of the ringbuffer
although it is recommended for optimal performance.

@accum will hold a temporary accumulator used in rate conversion and should be
set to 0 when this function is first called. In case the commit operation is
interrupted, one can resume the processing by passing the previously returned
@accum value back to this function.
