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.

Improve the spa_ump_to_midi function so that it can consume multiple UMP
messages and produce multiple midi messages.
Some UMP messages (like program changes) need to be translated into up
to 3 midi messages. Do this byt adding a state to the function and by
making it consume the input bytes, just like the spa_ump_from_midi
function.
Adapt code to this new world. This is a little API break..
At the moment errors are printed using `pw_log_error()`, however, that does
not display them by default because `client.conf` sets `log.level=0`.
Use `fprintf()` and always print the errors.
Make a new body.h file with some functions to deal with pod and their
body. Make the iter.h functions use mostly this.
Rework the parser so that it only uses body.h functions. With the separation
of pod+body, we can read and verify the pod once and then use the
verified copy to handle the rest of the body safely.
We do this because iter.h only works in pods in memory that doesn't change
because it is vulnerable to modifications of the data after verifying it.
The new parser is not vulnerable to this and will not cause invalid
memory access when used on shared memory. There is however no need for
atomic operations to read the headers, whever is read is either valid
and useable of invalid and rejected.
