|
|
<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/audio/gstaudioaggregator.c">Subclasses must use (a subclass of) #GstAudioAggregatorPad for both
|
|
their source and sink pads,
|
|
gst_element_class_add_static_pad_template_with_gtype() is a convenient
|
|
helper.
|
|
|
|
#GstAudioAggregator can perform conversion on the data arriving
|
|
on its sink pads, based on the format expected downstream: in order
|
|
to enable that behaviour, the GType of the sink pads must either be
|
|
a (subclass of) #GstAudioAggregatorConvertPad to use the default
|
|
#GstAudioConverter implementation, or a subclass of #GstAudioAggregatorPad
|
|
implementing #GstAudioAggregatorPadClass.convert_buffer.
|
|
|
|
To allow for the output caps to change, the mechanism is the same as
|
|
above, with the GType of the source pad.
|
|
|
|
See #GstAudioMixer for an example.
|
|
|
|
When conversion is enabled, #GstAudioAggregator will accept
|
|
any type of raw audio caps and perform conversion
|
|
on the data arriving on its sink pads, with whatever downstream
|
|
expects as the target format.
|
|
|
|
In case downstream caps are not fully fixated, it will use
|
|
the first configured sink pad to finish fixating its source pad
|
|
caps.
|
|
|
|
A notable exception for now is the sample rate, sink pads must
|
|
have the same sample rate as either the downstream requirement,
|
|
or the first configured pad, or a combination of both (when
|
|
downstream specifies a range or a set of acceptable rates).
|
|
|
|
The #GstAggregator::samples-selected signal is provided with some
|
|
additional information about the output buffer:
|
|
- "offset" G_TYPE_UINT64 Offset in samples since segment start
|
|
for the position that is next to be filled in the output buffer.
|
|
- "frames" G_TYPE_UINT Number of frames per output buffer.
|
|
|
|
In addition the gst_aggregator_peek_next_sample() function returns
|
|
additional information in the info #GstStructure of the returned sample:
|
|
- "output-offset" G_TYPE_UINT64 Sample offset in output segment relative to
|
|
the output segment's start where the current position of this input
|
|
buffer would be placed
|
|
- "position" G_TYPE_UINT current position in the input buffer in samples
|
|
- "size" G_TYPE_UINT size of the input buffer in samples</doc>

<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/audio/gstaudiobasesink.h">This function is set with gst_audio_base_sink_set_custom_slaving_callback()
|
|
and is called during playback. It receives the current time of external and
|
|
internal clocks, which the callback can then use to apply any custom
|
|
slaving/synchronization schemes.
|
|
|
|
The external clock is the sink's element clock, the internal one is the
|
|
internal audio clock. The internal audio clock's calibration is applied to
|
|
the timestamps before they are passed to the callback. The difference between
|
|
etime and itime is the skew; how much internal and external clock lie apart
|
|
from each other. A skew of 0 means both clocks are perfectly in sync.
|
|
itime > etime means the external clock is going slower, while itime < etime
|
|
means it is going faster than the internal clock. etime and itime are always
|
|
valid timestamps, except for when a discontinuity happens.
|
|
|
|
requested_skew is an output value the callback can write to. It informs the
|
|
sink of whether or not it should move the playout pointer, and if so, by how
|
|
much. This pointer is only NULL if a discontinuity occurs; otherwise, it is
|
|
safe to write to *requested_skew. The default skew is 0.
|
|
|
|
The sink may experience discontinuities. If one happens, discont is TRUE,
|
|
itime, etime are set to GST_CLOCK_TIME_NONE, and requested_skew is NULL.
|
|
This makes it possible to reset custom clock slaving algorithms when a
|
|
discontinuity happens.</doc>

|
result of the map operation in @buffer.
|
|
|
|
This is especially useful when the @gstbuffer is in non-interleaved (planar)
|
|
layout, in which case this function will use the information in the
|
|
@gstbuffer's attached #GstAudioMeta in order to map each channel in a
|
|
separate "plane" in #GstAudioBuffer. If a #GstAudioMeta is not attached
|
|
on the @gstbuffer, then it must be in interleaved layout.
|
|
|
|
If a #GstAudioMeta is attached, then the #GstAudioInfo on the meta is checked
|
|
against @info. Normally, they should be equal, but in case they are not,
|
|
a g_critical will be printed and the #GstAudioInfo from the meta will be
|
|
used.
|
|
|
|
In non-interleaved buffers, it is possible to have each channel on a separate
|
|
#GstMemory. In this case, each memory will be mapped separately to avoid
|
|
copying their contents in a larger memory area. Do note though that it is
|
|
not supported to have a single channel spanning over two or more different
|
|
#GstMemory objects. Although the map operation will likely succeed in this
|
|
case, it will be highly sub-optimal and it is recommended to merge all the
|
|
memories in the buffer before calling this function.
|
|
|
|
Note: The actual #GstBuffer is not ref'ed, but it is required to stay valid

as long as it's mapped.</doc>

## Using GstAudioCdSrc-based elements in applications
|
|
|
|
GstAudioCdSrc registers two #GstFormat<!-- -->s of its own, namely
|
|
the "track" format and the "sector" format. Applications will usually
|
|
only find the "track" format interesting. You can retrieve that #GstFormat
|
|
for use in seek events or queries with gst_format_get_by_nick("track").
|
|
|
|
In order to query the number of tracks, for example, an application would
|
|
set the CDDA source element to READY or PAUSED state and then query the
|
|
the number of tracks via gst_element_query_duration() using the track
|
|
format acquired above. Applications can query the currently playing track
|
|
in the same way.
|
|
|
|
Alternatively, applications may retrieve the currently playing track and
|
|
the total number of tracks from the taglist that will posted on the bus
|
|
whenever the CD is opened or the currently playing track changes. The
|
|
taglist will contain GST_TAG_TRACK_NUMBER and GST_TAG_TRACK_COUNT tags.
|
|
|
|
Applications playing back CD audio using playbin and cdda://n URIs should
|
|
issue a seek command in track format to change between tracks, rather than
|
|
setting a new cdda://n+1 URI on playbin (as setting a new URI on playbin
|
|
involves closing and re-opening the CD device, which is much much slower).
|
|
|
|
## Tags and meta-information
|
|
|
|
CDDA sources will automatically emit a number of tags, details about which
|
|
can be found in the libgsttag documentation. Those tags are:
|
|
#GST_TAG_CDDA_CDDB_DISCID, #GST_TAG_CDDA_CDDB_DISCID_FULL,
|
|
#GST_TAG_CDDA_MUSICBRAINZ_DISCID, #GST_TAG_CDDA_MUSICBRAINZ_DISCID_FULL,
|
|
among others.
|
|
|
|
## Tracks and Table of Contents (TOC)
|
|
|
|
Applications will be informed of the available tracks via a TOC message
|
|
on the pipeline's #GstBus. The #GstToc will contain a #GstTocEntry for
|
|
each track, with information about each track. The duration for each
|
|
track can be retrieved via the #GST_TAG_DURATION tag from each entry's
|
|
tag list, or calculated via gst_toc_entry_get_start_stop_times().
|
|
The track entries in the TOC will be sorted by track number.</doc>

These are the channels defined in SMPTE 2036-2-2008
|
|
Table 1 for 22.2 audio systems with the Surround and Wide channels from
|
|
DTS Coherent Acoustics (v.1.3.1) and 10.2 and 7.1 layouts. In the caps the
|
|
actual channel layout is expressed with a channel count and a channel mask,
|
|
which describes the existing channels. The positions in the bit mask correspond
|
|
to the enum values.
|
|
For negotiation it is allowed to have more bits set in the channel mask than
|
|
the number of channels to specify the allowed channel positions but this is
|
|
not allowed in negotiated caps. It is not allowed in any situation other
|
|
than the one mentioned below to have less bits set in the channel mask than
|
|
the number of channels.
|
|
|
|
@GST_AUDIO_CHANNEL_POSITION_MONO can only be used with a single mono channel that
|
|
has no direction information and would be mixed into all directional channels.
|
|
This is expressed in caps by having a single channel and no channel mask.
|
|
|
|
@GST_AUDIO_CHANNEL_POSITION_NONE can only be used if all channels have this position.
|
|
This is expressed in caps by having a channel mask with no bits set.
|
|
|
|
As another special case it is allowed to have two channels without a channel mask.
|
|
This implicitly means that this is a stereo stream with a front left and front right
|
|
channel.</doc>

<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/audio/gstaudiodecoder.c">This base class is for audio decoders turning encoded data into
|
|
raw audio samples.
|
|
|
|
GstAudioDecoder and subclass should cooperate as follows.
|
|
|
|
## Configuration
|
|
|
|
* 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).
|
|
* 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.
|
|
* GstAudioDecoder calls @stop at end of all processing.
|
|
|
|
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.
|
|
|
|
## Data processing
|
|
* 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.
|
|
* Input frame is provided to subclass' @handle_frame.
|
|
* If codec processing results in decoded data, subclass should call
|
|
@gst_audio_decoder_finish_frame to have decoded data pushed
|
|
downstream.
|
|
* 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.
|
|
* 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.
|
|
|
|
## Shutdown phase
|
|
|
|
* GstAudioDecoder class calls @stop to inform the subclass that data
|
|
parsing will be stopped.
|
|
|
|
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. Note that this
|
|
feature is only available if the buffer layout is interleaved. For planar
|
|
buffers, the decoder implementation is fully responsible for the output
|
|
buffer size.
|
|
|
|
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:
|
|
|
|
* Provide pad templates
|
|
* Set source pad caps when appropriate
|
|
* Set user-configurable properties to sane defaults for format and
|
|
implementing codec at hand, and convey some subclass capabilities and
|
|
expectations in context.
|
|
|
|
* 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.</doc>

|
<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/audio/gstaudioencoder.c">This base class is for audio encoders turning raw audio samples into
|
|
encoded audio data.
|
|
|
|
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
|
|
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
|
|
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:
|
|
|
|
* 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
|
|
gst_audio_encoder_finish_frame().</doc>

<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/audio/gstaudiofilter.c">#GstAudioFilter is a #GstBaseTransform<!-- -->-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 class_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.</doc>

Output samples will be quantized to a multiple of @quantizer. Better
|
|
performance is achieved when @quantizer is a power of 2.
|
|
|
|
Dithering and noise-shaping can be performed during quantization with
|
|
the @dither and @ns parameters.</doc>

<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/audio/gstaudiosrc.c">This is the most simple base class for audio sources that only requires
|
|
subclasses to implement a set of simple functions:
|
|
|
|
* `open()` :Open the device.
|
|
* `prepare()` :Configure the device with the specified format.
|
|
* `read()` :Read samples from the device.
|
|
* `reset()` :Unblock reads and flush the device.
|
|
* `delay()` :Get the number of samples in the device but not yet read.
|
|
* `unprepare()` :Undo operations done by prepare.
|
|
* `close()` :Close the device.
|
|
|
|
All scheduling of samples and timestamps is done in this base class
|
|
together with #GstAudioBaseSrc using a default implementation of a
|
|
#GstAudioRingBuffer that uses threads.</doc>

|
In DSD, the "sample format" is the bit. Unlike PCM, there are no further
|
|
"sample formats" in DSD. However, in software, DSD bits are grouped into
|
|
bytes (since dealing with individual bits is impractical), and these bytes
|
|
in turn are grouped into words. This becomes relevant when interleaving
|
|
channels and transmitting DSD data through audio APIs. The different
|
|
types of grouping DSD bytes are referred to as the "DSD grouping forma"
|
|
or just "DSD format". #GstDsdFormat has a list of valid ways of grouping
|
|
DSD bytes into words.
|
|
|
|
DSD rates are equivalent to PCM sample rates, except that they specify
|
|
how many DSD bytes are consumed per second. This refers to the bytes per
|
|
second _per channel_; the rate does not change when the number of channel
|
|
changes. (Strictly speaking, it would be more correct to measure the
|
|
*bits* per second, since the bit is the DSD "sample format", but it is
|
|
more practical to use bytes.) In DSD, bit rates are always an integer
|
|
multiple of the CD audio rate (44100) or the DAT rate (48000). DSD64-44x
|
|
is 44100 * 64 = 2822400 bits per second, or 352800 bytes per second
|
|
(the latter would be used in this info structure). DSD64-48x is
|
|
48000 * 64 = 3072000 bits per second, or 384000 bytes per second.
|
|
#GST_DSD_MAKE_DSD_RATE_44x can be used for specifying DSD-44x rates,
|
|
*and #GST_DSD_MAKE_DSD_RATE_48x can be used for specifying DSD-48x ones.
|
|
Also, since DSD-48x is less well known, when the multiplier is given
|
|
without the 44x/48x specifier, 44x is typically implied.
|
|
|
|
It is important to know that in DSD, different format widths correspond
|
|
to different playtimes. That is, a word with 32 DSD bits covers two times
|
|
as much playtime as a word with 16 DSD bits. This is in contrast to PCM,
|
|
where one word (= one PCM sample) always covers a time period of 1/samplerate,
|
|
no matter how many bits a PCM sample is made of. For this reason, DSD
|
|
and PCM widths and strides cannot be used the same way.
|
|
|
|
Multiple channels are arranged in DSD data either interleaved or non-
|
|
interleaved. This is similar to PCM. Interleaved layouts rotate between
|
|
channels and words. First, word 0 of channel 0 is present. Then word
|
|
0 of channel 1 follows. Then word 0 of channel 2 etc. until all
|
|
channels are through, then comes word 1 of channel 0 etc.
|
|
|
|
Non-interleaved data is planar. First, all words of channel 0 are
|
|
present, then all words of channel 1 etc. Unlike interleaved data,
|
|
non-interleaved data can be sparse, that is, there can be space in
|
|
between the planes. the @positions array specifies the plane offsets.
|
|
|
|
In uncommon cases, the DSD bits in the data bytes can be stored in reverse
|
|
order. For example, normally, in DSDU8, the first byte contains DSD bits
|
|
0 to 7, and the most significant bit of that byte is DSD bit 0. If this
|
|
order is reversed, then bit 7 is the first one instead. In that ase,
|
|
@reversed_bytes is set to TRUE.

|
such elements are #volume and #playbin.
|
|
|
|
Applications can use this interface to get or set the current stream volume. For this
|
|
the "volume" #GObject property can be used or the helper functions gst_stream_volume_set_volume()
|
|
and gst_stream_volume_get_volume(). This volume is always a linear factor, i.e. 0.0 is muted
|
|
1.0 is 100%. For showing the volume in a GUI it might make sense to convert it to
|
|
a different format by using gst_stream_volume_convert_volume(). Volume sliders should usually
|
|
use a cubic volume.
|
|
|
|
Separate from the volume the stream can also be muted by the "mute" #GObject property or
|
|
gst_stream_volume_set_mute() and gst_stream_volume_get_mute().
|
|
|
|
Elements that provide some kind of stream volume should implement the "volume" and
|
|
"mute" #GObject properties and handle setting and getting of them properly.
|
|
The volume property is defined to be a linear volume factor.</doc>

|
|
result of the map operation in @buffer.
|
|
|
|
This is especially useful when the @gstbuffer is in non-interleaved (planar)
|
|
layout, in which case this function will use the information in the
|
|
@gstbuffer's attached #GstAudioMeta in order to map each channel in a
|
|
separate "plane" in #GstAudioBuffer. If a #GstAudioMeta is not attached
|
|
on the @gstbuffer, then it must be in interleaved layout.
|
|
|
|
If a #GstAudioMeta is attached, then the #GstAudioInfo on the meta is checked
|
|
against @info. Normally, they should be equal, but in case they are not,
|
|
a g_critical will be printed and the #GstAudioInfo from the meta will be
|
|
used.
|
|
|
|
In non-interleaved buffers, it is possible to have each channel on a separate
|
|
#GstMemory. In this case, each memory will be mapped separately to avoid
|
|
copying their contents in a larger memory area. Do note though that it is
|
|
not supported to have a single channel spanning over two or more different
|
|
#GstMemory objects. Although the map operation will likely succeed in this
|
|
case, it will be highly sub-optimal and it is recommended to merge all the
|
|
memories in the buffer before calling this function.
|
|
|
|
Note: The actual #GstBuffer is not ref'ed, but it is required to stay valid
|
|
as long as it's mapped.</doc>

writable for that purpose. The fields of the #GstDsdPlaneOffsetMeta are
|
|
directly populated from the arguments of this function.
|
|
|
|
If @offsets is NULL, then the meta's offsets field is left uninitialized.
|
|
This is useful if for example offset values are to be calculated in the
|
|
meta's offsets field in-place. Similarly, @num_bytes_per_channel can be
|
|
set to 0, but only if @offsets is NULL. This is useful if the number of
|
|
bytes per channel is known only later.
|
|
|
|
It is not allowed for channels to overlap in memory,
|
|
i.e. for each i in [0, channels), the range
|
|
[@offsets[i], @offsets[i] + @num_bytes_per_channel) must not overlap
|
|
with any other such range. This function will assert if the parameters
|
|
specified cause this restriction to be violated.
|
|
|
|
It is, obviously, also not allowed to specify parameters that would cause
|
|
out-of-bounds memory access on @buffer. This is also checked, which means
|
|
that you must add enough memory on the @buffer before adding this meta.
|
|
|
|
This meta is only needed for non-interleaved (= planar) DSD data.</doc>

@num_bytes must be an integer multiple of the width of both input
|
|
and output format. For example, if the input format is GST_DSD_FORMAT_U32LE,
|
|
and the output format is GST_DSD_FORMAT_U16BE, then @num_bytes must
|
|
be an integer multiple of both 4 (U32LE width) and 2 (U16BE width).
|
|
|
|
@reverse_byte_bits is necessary if the bit order within the DSD bytes
|
|
needs to be reversed. This is rarely necessary, and is not to be
|
|
confused with the endianness of formats (which determines the ordering
|
|
of *bytes*).
|

|
@input_plane_offsets must not be NULL if @input_layout is set to
|
|
#GST_AUDIO_LAYOUT_NON_INTERLEAVED. The same applies to @output_plane_offsets.
|
|
These plane offsets define the starting offset of the planes (there is
|

exactly one plane per channel) within @input_data and @output_data
|

respectively. If GST_AUDIO_LAYOUT_INTERLEAVED is used, the plane offsets
