config.h needs to be consistently included before any standard headers
if we ever want to set feature test macros (like _GNU_SOURCE or whatever)
inside. It can lead to hard-to-debug issues without that.
It can also be problematic just for our own HAVE_* that it may define
if it's not consistently made available before our own headers. Just
always include it first, before everything.
We already did this in many files, just not consistently.
When we simply need to change some state for the code executed in the
loop, we can use locked() instead of invoke(). This is more efficient
and avoids some context switches in the normal case.
Including C headers inside of `extern "C"` breaks use from C++. Hoist
the includes of standard C headers above the block so we don't try
to mangle the stdlib.
I initially tried to scope this with a targeted change but it's too
hard to do correctly that way. This way, we avoid whack-a-mole.
Firefox is working around this in their e21461b7b8b39cc31ba53c47d4f6f310c673ff2f

Bug: https://bugzilla.mozilla.org/1953080
Make the state_changed event and _get_state() function set errno with
the current error value if the state is in error, so that application
can use this to give more detailed error reporting.
Use this in alsa, v4l2 and pulse to give some other error codes than
EIO.
Fixes#4574
We use the remote name as a suffix for the default server address and so
it should not contain any slashes. Take everything after the last slash
if there is one.
When we write samples, check if we make a jump in the ringbuffer and
clear the samples we jumped over.
If we don't do this, the reader side might pick up old samples that we
didn't write or clear but that are now available for reading after we
made a jump in the ringbuffer.
This migh not be exactly what pulseaudio does but it is good for now.
Fixes#4464
So that a config override can disable the execution of the command by
setting the property to false in the pulse.properties config override.
Expose some conf.c method for this purpose.
Set the corked state on streams so that we can use this in sink-input
and source-output info without guessing.
The problem is that when a stream starts un-corked, the state is less
than RUNNING and so before this patch, pulse-server reports a corked
stream, which is not what pulseaudio reports.
Make `client_queue_subscribe_event()` take the facility and type
separately, and calculate the mask itself, so that the caller
does not need to be concerned with that.
Use the helper instead of duplicating the same code.
Also add some helpers to parse a json array of uint32_t
Move some functions to convert between type name and id.
This gets the next key and value from an object. This function is better
because it will skip key/value pairs that don't fit in the array to hold
the key.
The previous code patter would stop parsing the object as soon as a key
larger than the available space was found.
Add spa_json_begin_array/object to replace
spa_json_init+spa_json_begin_array/object
This function is better because it does not waste a useless spa_json
structure as an iterator. The relaxed versions also error out when the
container is mismatched because parsing a mismatched container is not
going to give any results anyway.
Since `spa/utils/cleanup.h` is not a private header anymore, there is
no need for a separate `pipewire/cleanup.h` since the definitions of
the cleanup routines can now be moved into the respective headers.
Don't spam the warning about kernel missing features required for snap
on every pulseaudio connection, but instead show it only once, as the
situation is not going to improve.
PulseAudio's property list can store arbitrary data, but
pw_properties can only store null-terminated strings.
So for the time being, ignore those values that don't
have null-terminators or have zero bytes inside.
The length of the value for each value in a property list is serialized
twice. Both the reference implementation and pipewire-pulse send
the same length, so be stricter and only accept a property list
if both lengths are the same.
Add pw_conf_section_update_props_rules() that will not only update the
properties of a section but wil also apply rules in section.rules and
match against the context properties.
Use this by default when using pw_context_conf_update_props().
Add a new method to get a string name of the VM type. Place the
cpu.vm.name in the context properties.
This makes it possible to deprecate the vm.overrides with something more
flexible based on rules. Update the conf files and docs to refect this.
Add a monitor.passthrough option. This will pass all latency information
directly between the port and its monitor ports.
This is interesting when the adapter (and audioconvert) is used with a
null-audio-sink that simply forwards the data to a real sink/souce. In
that case, we want the sink/source latency to be passed unmodified.
Set the monitor.passthrough on the pulseaudio null-sink because
a passthrough virtual sink is the most likely use case for this.
Add some monitor.passthrough default config where it makes sense.
Fixes#3888
Add a client that subscribes to the list of subscribers and make the
client watch for EnumFormat changes.
When a subscribed client sees an EnumFormat change for a sink, emit EVENT
to the client.
This will send the EVENT to pavucontrol when the supported IEC958
formats change so that it can update the gui.
