Memory Safety: High
In dot_data_init(), the return value of malloc() was not checked before
dereferencing, causing a NULL pointer dereference if allocation fails.
In dot_data_ensure_max_size(), the return value of realloc() was
assigned directly to dd->data without checking for NULL, which both
loses the original pointer (memory leak) and causes a NULL pointer
dereference on subsequent use.
Add NULL checks for both cases. For realloc, use a temporary variable
to preserve the original pointer on failure.

There is nothing wrong with the use of strcat here but security tools
keep complaining about it and creating bad patches for it so fix it
with a strbuf.
SF_FORMAT_WAVEX is not supported to SF_ENDIAN_CPU. Due to that, unable
to record in .wav file (for > 2 channels). Add case for SF_FORMAT_WAVEX
to get assign SF_ENDIAN_FILE.
Fixes#5233
Takes an input file, processes it with audioconvert and writes to an
output file. Can be used to test all audioconvert features such as
resample, channelmix, filter-graph, format conversion, dither, etc.
Boilerplate written by Claude.
The object, node, client, factory, module, and link IDs are all uint32_t values but were being formatted with %d.
This would produce incorrect negative values if an ID ever exceeded INT_MAX
COLS could be very small and the statusbar array might overflow with
strcpy and strcat. Also initializing the variable array seems to cause
problems on older compilers.
Instead use a fixed array that is big enough to hold all possible
values we write into it.
Add a standalone tool that creates virtual AVB talker/listener endpoints
visible in the PipeWire graph (e.g. Helvum). Uses the loopback transport
so no AVB hardware or network access is needed.
The sink node consumes audio silently, the source produces silence.
Supports --milan flag for Milan v1.2 mode and --name for custom node
name prefix.

We might overflow the path buffer when we strcat the provided filename
into it, which might crash or cause unexpected behaviour.
Instead use spa_scnprintf which avoids overflow and properly truncates
and null-terminates the string.
Found by Claude Code.
Add a control.ump port property. When true, the port wants UMP and the
mixer will convert to it. When false, the port supports both UMP and
Midi1 and no conversions will happen. When unset, the mixer will always
convert UMP to midi1.
Remove the CONTROL_types property from the filter. This causes problems
because this is the format negotiated with peers, which might not
support the types but can still be linked because the mixer will
convert.
The control.ump port property is supposed to be a temporary fix until we
can negotiate the mixer ports properly with the CONTROL_types.
Remove UMP handling from bluetooth midi, just use the raw Midi1 events
now that the mixer will give those and we are supposed to output our
unconverted format.
Fix midi events in-place in netjack because we can.
Update docs and pw-mididump to note that we are back to midi1 as the
default format.
With this, most of the midi<->UMP conversion should be gone again and we
should be able to avoid conversion problems in ALSA and PipeWire.
Fixes#5183
We keep a mapping between the sndfile formats and the format we would
like to decode them to for encoded formats. Make sure we don't mix up
the sample widths between them.
Make sure we don't send encoded formats as raw.
Debug the uncompressed format name correctly.
Fixes#5155
Remove custom json serialization code and use the new json-builder
from various tools.
spa-json-dump now has color and raw mode and can probably be simplified
a bit more.
The properties can now serialize arbitrarily large keys, which makes
a unit test work. It also has a new 'simple' option for SPA output,
which is added and used in pw-config.
Add a container option to override the extension check and force a
container when saving.
Add some more formats that are supported by libsndfile.
Add some options to list all supported formats, extensions/containers,
layouts and channel names.
Fixes#5117
The simple formats contain some common mappings for other extensions such
as mp3.
Makes pw-record test.mp3 actually write an mp3 instead of a wav file.
Move the latency print code after where we print the port. That way
we only get the latency when we first print the port.
Avoid -lt from printing latencies for ports without a link.
The raw mode -a only supported reading raw data from stdin/stdout and
simply ignored the filename. Make it use the filename to determine
where to read from instead.
Support stdin/stdout for sysex mode as well and close the file when we
are done.
Fixes#5012
Add a function that accepts the size of the position array when reading
the audio positions. This makes it possible to decouple the position
array size from SPA_AUDIO_MAX_CHANNELS.
Also use SPA_N_ELEMENTS to pass the number of array elements to
functions instead of a fixed constant. This makes it easier to change
the array size later to a different constant without having to patch up
all the places where the size is used.
Now that the server asks for the right amount of samples for DSD, just
give it the right amount of samples without doing some weird scaling.
Make a method to calculate the size (stride) of one sample, which
depends on the interleave and channels of the stream.
See !2540
Rework how the monitor mode works. Instead of having separate paths for
the list and monitor mode, reuse the list mode. We simply mark all
changes and then list the changes in a loop.
This makes it possible to accumulate some updates and print them
together.
Add a -t option to list the latency params on a port.
Add sample limit switch -n to pw-cat to stop the recording or playback
after a set number of samples received.
