Add a _fast callback function that skips the version and method check.
We can use this in places where performance is critical when we do the
check out of the critical loops.
Make all system methods _fast calls. We expect them to exist and have
the right version. If we add new versions we can make them slow.
Add port.ignore-latency prop, which if true causes peer ports to ignore
the latency of the given port.
This is useful for ports that are not intended to affect latency
calculations of other ports, such as ports in monitor streams.
The WebRTC echo canceler can support different rates and channels for
the record, out and playback streams.
Add a new method to pass this config to the echo-canceler.
Add check for running the the loop context and thread.
Add checks in filter and stream to avoid doing things when not run from
the context main-loop because this can crash things when doing IPC from
concurrent threads.
Place the target rate and duration in the io clock area.
The driver is meant to read these new values at the start of the cycle
and update the position rate and duration.
This used to be done by the pipewire server when it received the ready
callback from the driver but this is in fact too late. Most driver would
start processing and set the next timeout based on the old rate/duration
instead of the new pending ones.
There is still a fallback for the old behaviour (with a warning) when
the driver doesn't yet update the position.
Single argument static_assert() is only available since
C++17 and C23. Some compilers accept it even in earlier language
versions, but some do not.
Single argument static assertions can be supported by using
a GCC extensions, namely that `, ## __VA_ARGS__` removes the
comma if the variadic argument list is empty. This enables a
construction which passes a pre-determined string as the second
argument of the underlying static_assert() when only a single
argument is used in the `SPA_STATIC_ASSERT()` macro.

WirePlumber checks for the ENCODED audio format to determine if the
format is compressed/encoded. Without this info, it is not able
to automatically link compressed audio nodes.
Make a real debug context with a log function and move it to a new file.
This way we don't need to redefine a macro.
Make a new context for debugging to a log file. Make new functions to
debug to a log file.
Move the stringbuffer to string utils.
Integrate file/line/func and topics into the debug log.
We can remove some more things from the pipewire log_object function and
also add support for topics.
Add new spa_debugc_ funnctions that take a context. The user should also
redefine the spa_debugc macro to handle the context.
Use this to let some plugins log the pod and format to the log without
using the global logger.
Also use this to remove our custom pod logger function by reusing the
spa one with a custom context.
Add SPA_SCALE32_UP that scales a uint32 without overflow.
Use this for scaling the threshold in ALSA.
Fix the scaling in audioconvert of the buffer size, the scaling was
wrong and it was also causing an overflow resulting in choppy sound in
some cases.
See #2680
Split files into separate files.
Move type annotations to a matching -types.h files.
Move helpers to matching -utils.h files.
Add helpers to parse generic audio and video info.
The drm format modifier value `0` is actually `DRM_FORMAT_MOD_LINEAR`,
a commonly used modifier. Unfortunately there appears to be no value
that can savely used as placeholder for "no value", as e.g.
`DRM_FORMAT_MOD_INVALID` is often used to indicate an implicit modifier.
Thus add a new flag that clearly indicates whether the modifier
value is set or not, add it to `spa_video_info_raw` and the util
functions.

This metadata can be used to signal that a buffer is transformed.
The values are intentionally choosen to coincide with
wl_output::transform from the wayland windowsystem.
Just like the optional build, make all field parsing optional. This
will leave the fields with their default values if they are not parsed
from the param.
We can then remove our custom functions and use the generic ones in
various places.
