Add a module for a fallback dummy sink, which appears dynamically when
no other sinks are present.
Enable it for pipewire-pulse, because Pulseaudio will also show
dynamically a dummy sink.
I don't think PipeWire currently has a way to temporarily alias
module-rtkit to module-rt though, so right now this would break realtime
scheduling for people with modified configs that use module-rtkit.
Use `meson.project_{build,source}_root()` instead of
`meson.{build,source}_root()` because those functions
do not work as expected when used inside a subproject,
and they have been deprecated in meson 0.56.0.
Use this to override the default $PIPEWIRE_CONFIG_DIR/media-session.d
directory. This allows us to have separate configuration directories for
pipewire and media-session.
Make Doxygen see also macros defined inside struct declarations,
and to include also opaque structs.
Keep members in the order they are in the .h file, since Doxygen's
case-insensitive sort by name jumbles things.
The Doxygen autogenerated graphs are very useful and take up lots of
space being on the top, so disable them.
Also disable references/referenced by relations, which add clutter.
Also hide most macro values.
The Doxygen "Modules" page is not very illuminative, as different parts
of the API are mixed together and not all parts are included.
Try to address this:
Put all parts of the public API to some Doxygen group, usually one group
per header file. Use short, systematic names.
Make these groups sub-groups of a few top-level groups, roughly
corresponding to the different logical parts of the API (core, impl,
stream, filter, spa, utilities).
Add an input filter that tries to link e.g.
#define pw_core_add_listener(...) pw_core_method(c,add_listener,...)
to the corresponding declaration in struct pw_core_methods.
Make Doxygen data structure etc. lists less cluttered by hiding
non-public stuff.
Add a Doxygen input filter that marks symbols declared in C files
private, so that they won't appear in the output unless the symbol is
also declared in a header.
The "spa static inline" hack is then also not needed any more.
Media-session itself uses ms.core, there are only two files that could
have a sub-topic but right now they don't use it (match-rules and
metadata).
The modules use the ms.mod.* namespace, so it's trivial to filter on
those.
pw_log_log/logv now go through the topic-based logger using the
"default" topic. Log topics themselves can be allocated by the call
sites. The simplest way to use a topic from e.g. a module:
PW_LOG_TOPIC_STATIC(mod_topic, "mod.foo");
#define PW_LOG_TOPIC_DEFAULT mod_topic
...
void pipewire__module_init() {
PW_LOG_TOPIC_INIT(mod_topic);
...
}
With the #define all pw_log_foo() are now routed through the custom
topic. For the cases where the log topic must be specified, a
pw_logt_foo() set of macros is available.
Log topics are enabled through the PIPEWIRE_DEBUG environment variable
which now supports globs, e.g. PIPEWIRE_DEBUG="*:I;mod.access:D"
to enable global INFO but DEBUG for the access module.
Namespaces documented are "pw", "mod" and "conn", for pipewire-internal
stuff, modules and connection dumping. The latter is special-cased to
avoid spamming the log files, it requires an expcit "conn.<glob>"
pattern to enable.
The "default" topic always exists and is the fallback for any
pw_log_foo() invocation that does not use a topic.
Allow one of "XEWIDT" to refer to none, errors, warnings, info, debug
and trace, respectively because they're immediately recognizable. Well,
except maybe the X.
PIPEWIRE_DEBUG="I" is equivalent to PIPEWIRE_DEBUG="3" for example.
This is a multi-step process involving 4 processes and two modules.
Let's add some graphs to make this slightly easier to comprehend for
those not familiar with how portals work.
A list of reasons why DMA-BUFs have to be treated specially. This
should make it clearer why mmaping DMA-BUFs should be avoided and hint
clients on how treat them correctly

Describing different behaviour for modifier-less and modifier-aware case
and how a EnumFormat with modifier should be fixated. Also adding a Note
about `SPA_PARAM_BUFFERS_blocks`, which is important for multiplane
DMA-BUFS.
Add module that switches bluez device profile to HFP/HSP if an input
stream (non-monitor, autoconnect) appears, and the current default
output device is bluez one that does not have input route.
When all input streams are gone, switch all changed profiles back.
Pending restore state is saved to session manager state files, in order
to restore it if e.g. devices get disconnected. This usually is not
currently necessary since the bluez5 plugin prefers to connect to A2DP
over HFP, but might matter in future with backchannel-enabled A2DP
codecs.
