/**
* SECTION:gstrawbaseparse
* @short_description: Base class for raw media data parsers
*
* This base class is for parsers which read raw media data and output
* timestamped buffers with an integer number of frames inside.
*
* The format of the raw media data is specified in one of two ways: either,
* the information from the sink pad's caps is taken, or the information from
* the properties is used (this is chosen by the use-sink-caps property).
* These two ways are internally referred to as "configurations". The configuration
* that receives its information from the sink pad's caps is called the
* "sink caps configuration", while the one that depends on the information from
* the properties is the "properties configuration". Configurations have a
* "readiness". A configuration is "ready" when it contains valid information.
* For example, with an audio parser, a configuration is not ready unless it
* contains a valid sample rate, sample format, and channel count.
*
* The properties configuration must always be ready, even right from the start.
* Subclasses must ensure this. The underlying reason is that properties have valid
* values right from the start, and with the properties configuration, there is
* nothing that readies it before actual data is sent (unlike with the sink caps
* configuration, where a sink caps event will ready it before data is pushed
* downstream).
*
* It is possible to switch between the configurations during a stream by
* setting the use-sink-caps property. Subclasses typically allow for updating the
* properties configuration during a stream by setting the various properties
* (like sample-rate for a raw audio parser).
* In these cases, the parser will produce a new CAPS event and push it downstream
* to announce the caps for the new configuration. This also happens if the sink
* caps change.
*
* A common mistake when trying to parse raw data with no input caps (for example,
* a file with raw PCM samples when using rawaudioparse) is to forget to set the
* use-sink-caps property to FALSE. In this case, the parser will report an error
* when it tries to access the current configuration (because then the sink caps
* configuration will be the current one and it will not contain valid values
* since no sink caps were seen at this point).
*
* Subclasses must ensure that the properties configuration is the default one.
*
* The sink caps configuration is mostly useful with push-based sources, because these
* will produce caps events and send them downstream. With pull-based sources, it is
* possible that this doesn't happen. Since the sink caps configuration requires a caps
* event to arrive at the sinkpad, this will cause the parser to fail then.
*
* The base class identifies the configurations by means of the GstRawAudioParseConfig
* enum. It instructs the subclass to switch between configurations this way, and
* also requests information about the current configuration, a configuration's
* frame size, its readiness, etc. Subclasses are not required to use any particular
* structure for the configuration implementations.
*
* Use the GST_RAW_BASE_PARSE_CONFIG_MUTEX_LOCK and GST_RAW_BASE_PARSE_CONFIG_MUTEX_UNLOCK
* macros to protect configuration modifications.
*
* <listitem>
* <itemizedlist>
* <title>Summary of the subclass requirements</title>
* <listitem><para>
* Sink caps and properties configurations must both be
* implemented and supported. It must also be ensured that there is a
* "current" configuration.
* </para></listitem>
* Modifications to the configurations must be protected with the
* GstRawBaseParse lock. This is typically necessary when the
* properties configuration is modified by setting new property values.
* (Note that the lock is held during *all* vfunc calls.)
* <listitem><para>
* If the properties configuration is updated (typically by
* setting new property values), gst_raw_base_parse_invalidate_src_caps()
* must be called if the properties config is the current one. This is
* necessary to ensure that GstBaseParse pushes a new caps event downstream
* which contains caps from the updated configuration.
* </para></listitem>
* <listitem><para>
* In case there are bytes in each frame that aren't part of the actual
* payload, the get_overhead_size() vfunc must be defined, and the
* @get_config_frame_size() vfunc must return a frame size that includes
* the number of non-payload bytes (= the overhead). Otherwise, the
* timestamps will incorrectly include the overhead bytes.
* </para></listitem>

* transferred to the caller. If something fails during the caps
* creation, the vfunc must make sure to destroy any partially
* created caps; the *caps value is always set to NULL in case of
* failure. Returns FALSE in case of failure,
* TRUE in case of success.
* @get_config_frame_size: Gets the size of one frame, in bytes, from the specified
* configuration. This must be the size of the complete frame,
* including any overhead (metadata, headers, padding bytes etc.).
* @get_max_frames_per_buffer: Optional.
* Returns up to how many complete frames one output buffer may
* contain. The value must be nonzero. This is useful for example
* with video parsers which need to ensure that one output buffer
* contains only one video frame, even if the input buffer contains
* several complete frames. If this vfunc is not set, then there
* is no maximum number of frames per buffer - the parser reads
* as many complete frames as possible from the input buffer.
* @is_config_ready: Returns TRUE if the specified configuration is ready, FALSE
* otherwise.
* @process: Optional.
* This is useful to do any last minute processing before the
* data is pushed downstream. One example is channel reordering
* in audio parsers.
* in_data is the complete input buffer, total_num_in_bytes is
* the total amount of bytes this input buffer contains (including
* excess bytes that form an incomplete rame). num_valid_in_bytes
* is the subset of these bytes that are to be pushed downstream.
* If for example the frame size is 4, and total_num_in_bytes is
* 411, then num_valid_in_bytes will be 408, since the last 3
* bytes form an incomplete frame.
* The value of num_valid_in_bytes excludes the overhead bytes
* indicated by @get_overhead_size.
* If the subclass creates a new buffer here, *processed_data
* must be set to the new buffer's pointer. If the subclass does
* not create any new buffer, and just expects the first
* num_valid_in_bytes of the input buffer to be pushed downstream,
* then *processed_data must be set to NULL.
* If this vfunc is not set, then the parser behaves as if this
* vfunc set *processed_data data to NULL.
* @is_unit_format_supported: Returns TRUE if the given format is supported by the
* @get_units_per_second function, FALSE otherwise.
* @get_units_per_second: Returns how many units per second exist for a given format.
* For example, with an audio parser and format DEFAULT, the units
* per second are typically the number of samples per second
* (= the sample rate). For video parsers, this would be the frame
* rate. If BYTES or TIME are used as format, then the result must
* not include any extra overhead (metadata, headers, padding etc.)
* @get_overhead_size: Optional.
* Returns the number of bytes that make up the portion of a frame
* that isn't payload. Examples are padding bytes, headers, and
* other kinds of metadata. If this vfunc isn't defined, then an
* overhead size of 0 bytes is assumed.
*
* Subclasses are required to override all vfuncs except for @process, which is optional.
* The raw base parser lock is held during all vfunc calls.

/* The checks use as test data an 8x8 Y444 image, with 25 Hz framerate. In the

* planes aren't tightly packed (there are 20 bytes between the planes), and the
* frames overall have padding between them (the overall frame size is
* stride (10) * height (8) * num-planes (3) + bytes-between-planes (20) * 2
* = 280 bytes, and the frame stride is 500 bytes, so there are 220 bytes of
* extra padding between frames).
*
* In the test 8x8 frame, the pixels are all set to #000000, except for two
* pixels: (xofs+1 yofs+0) is set to #8899AA, (xofs+0 yofs+1) is set to #112233.
* The first frame uses the offsets xofs=0 yofs=0. The second frame uses
* xofs=1 yofs=0 etc. For each configuration, there is a separate set of frames,
* each stored in the GstAdapter in the Context struct.
*
* During the tests, as part of the checks, the pixels are verified to have the
* right values. The pattern of the pixels was chosen to easily detect stride
