Memory Safety: Medium
strcpy was used to copy port names into fixed-size buffers
(REAL_JACK_PORT_NAME_SIZE+1) without explicit bounds checking.
Port names originate from JACK client API calls and PipeWire
port info, which are external inputs. Replaced with snprintf
using sizeof(destination) to guarantee the copy is always
bounded, preventing potential buffer overflows if source
strings exceed the expected maximum length.

Memory Safety: Low
sprintf was used to format a temporary filename into an alloca'd
buffer. While the buffer was correctly sized (strlen + 5), using
snprintf with an explicit size makes the bound check enforceable
and prevents potential overflow if the sizing logic is modified
in the future.

Memory Safety: Low
sprintf was used to format MD5 hex digest bytes into a fixed-size
buffer without explicit bounds. While the output is bounded by the
fixed MD5 digest length (16 bytes = 32 hex chars), using snprintf
with an explicit size of 3 (2 hex chars + null) ensures correctness
even if the surrounding code changes.

sprintf was used to format a /proc path without bounds checking.
While pid_t values are practically bounded, using snprintf with
sizeof(root_path) ensures the buffer cannot overflow regardless
of the input value, following defense-in-depth principles.

Shuffle FFT output into real/imag blocks so that they are easier to
handle in the complex multiply. Do the unshuffle again before doing the
inverse FFT.
When streams are skipped via continue in updateDescriptors(),
the loop index i and descriptorSetLen diverge. The image info
is written at descriptorSetLen but pImageInfo was referencing
index i, pointing to uninitialized memory and causing incorrect
Vulkan descriptor updates.
Fix by using descriptorSetLen consistently.

We don't need 2 convolvers anymore, we can use the same convolver with
2 outputs with the left and right ir.
Add latency option to the sofa plugin. I believe the latency of the
SOFA filters is by default 0, so use that.
Add support for multiple convolver outputs. This makes things more
efficient because we only need to do the input FFT once to produce the N
outputs.
Add convolver2 that can have multiple outputs.
port_use_buffers and related port methods increment port_id when the
implicit output direction differs from the adapter's primary direction.
port_reuse_buffer only receives a port id but applies to output ports,
so apply the same offset before forwarding to this->target.
Also update videoadapter for the same mapping.
MT7925 fails to setup a SCO connection that results to working LC3-24kHz
audio. Other controllers (Intel etc) appear to work OK.
Add quirk for disabling this codec, and disable it for this Mediatek
controller.
We need to deactivate the graph when the format was cleared on both the
input and output. This means we got suspended and we need to clear. We
can safely do this now because we take the right locks.
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
The DSP port type needs to be something else than "other" for it
to become visible. This way we can also remove the IS_VISIBLE check
because we never add invisible ports to the object list.
ACP was re-selecting the “best” port on every port availability event,
even when a port was already explicitly selected by the user. This
differs from PulseAudio’s behavior, where port switching decisions are
left to higher-level policy.
This caused issues on devices where Line Out (speakers) and Headphones
share the same analog interface: when headphones are plugged in, ACP
would immediately switch away from the user-selected Line Out, or end up
in a state where no sound is produced despite selecting speakers explicitly from
clients like pwvucontrol.
Fix this by only re-evaluating and switching ports when:
- no active port is currently selected, or
- the active port has become unavailable
This preserves manual user choices and prevents ACP from fighting client
port selections during route activation.
Additionally, adjust ALSA mixer paths to better separate Line Out and
Headphones behavior:
- Disable Line Out controls in the headphones path
- Add explicit Line Out and Auto-Mute Mode handling in the lineout path
Together, these changes align PipeWire’s behavior more closely with
PulseAudio and fix cases where selecting speakers while headphones are
plugged results in no audio output.

1. The period calls were added to handle timeouts.
2. Handle the case where lock must be unlocked after 60s if the
controller owning the locked does not release it.
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
