Add gst_audio_ring_buffer_set_errored() that will mark the ringbuffer as errored only if it is currently started or paused, so gst_audio_ringbuffer_stop() can be sure that the error state means that the ringbuffer was started and needs stop called. Fixes a crash with osxaudiosrc if the source element posts an error, because the ringbuffer would not get stopped and CoreAudio would continue trying to do callbacks. Also, anywhere that modifies the ringbuffer state, make sure to use atomic operations, to guarantee their visibility Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5205>

|
|
<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>

<doc xml:space="preserve" filename="../subprojects/gst-plugins-base/gst-libs/gst/audio/gstaudiocdsrc.c">Provides a base class for CD digital audio (CDDA) sources, which handles
|
|
things like seeking, querying, discid calculation, tags, and buffer
|
|
timestamping.
|
|
|
|
## 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:
|
|

<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>

|
|
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>

for that purpose. The fields of the #GstAudioMeta are directly populated
|
|
from the arguments of this function.
|
|
|
|
When @info->layout is %GST_AUDIO_LAYOUT_NON_INTERLEAVED and @offsets is
|
|
%NULL, the offsets are calculated with a formula that assumes the planes are
|
|
tightly packed and in sequence:
|
|
offsets[channel] = channel * @samples * sample_stride
|
|
|
|
It is not allowed for channels to overlap in memory,
|
|
i.e. for each i in [0, channels), the range
|
|
[@offsets[i], @offsets[i] + @samples * sample_stride) 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.</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.
