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.
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.
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 method to update the client routes. Add an event when the client
routes changed.
Listen for route_changed events on clients that do a subscribe on the
stream-restore extension. Emit an EVENT when the routes change.
This keeps the system notifications volumes in sync between
gnome-control center and pavucontrol and probably in other tools
as well.
Fixes#3805
Add extension support to modules. This is a list of extension commands
that can be performed on the module.
Remove the custom registry of extensions and make proper modules that
implement the extensions.
This is more in line with what pulseaudio does. The advantage is that the
modules actually show up in the module list and that we can use the
module user_data to implement the extension later.
Add a function to check if a specfic custom log level has been defined
for a topic.
We can use this to dynamically check if we need to do the connection debug
messages.
We can also get rid of the conn.* pattern hack to disable connection
messages by default.
Also include and update the state of the device/stream in
collect_device_info so that we can compare it against the previous value
and emit a change event.
Fixes#3660
Instead of passing the pw_manager object, pass the client
object to the message handler. The client's manager can
still be accessed via `client->manager`. Furthermore,
message handlers now have access to `client->impl`.
Use `open_memstream()` to create a FILE stream and pass
that to message handlers to store their response. This allows
the `open_memstream()` calls and related error handling to be
removed from the message handlers.
`spa_streq()` already checks if any of its arguments
are NULL, and NULL is not considered equal to any non-NULL
string, therefore the check can be removed.
For sink nodes, keep a separate device_info around for the sink and
the monitor source part of the node. Only emit changes for the sink
and monitor source part when it changed.
See #3388
Make sure don't handle names ending in .monitor as a valid sink (because
it's a monitor on the sink).
Make sure we don't return a sink (monitor) as a source accidentally but
only when explicitly requested by name with the .monitor extension.
Makes
pactl set-sink-volume alsa_output.pci-0000_00_1b.0.analog-stereo.monitor -5%
pactl set-source-volume alsa_output.pci-0000_00_1b.0.analog-stereo -5%
fail as expected.
Tag the sink/source as HARDWARE when it's not virtual, the presence
of a DEVICE_API property is not a good check.
Make a method to check if a node is a NETWORK sink/source to make it
use the same logic everywhere.
@DEFAULT_MONITOR@ finds the default sink but returns is_monitor true.
Always lookup the device based on the name and index. This transform
the special device names like @DEFAULT_XXX@ to the default device.
Always use the found device name as the target. Make sure to set the
CAPTURE_SINK property when dealing with a monitor.
Fixes#3284
We need to be able to fill up one quantum of data when the stream
requests it so suggest a quantum_limit buffer size. Normally, the
converter will further improve the buffer size parameters when
resampling is involved but this is a good default for when working in
passthrough mode.
We don't actually use the stream buffering features so we're happy with
just 1 or 2 buffers.
Filling a buffer with zeros to produce silence is wrong for
unsigned sample formats and compressed sample formats. This is
silence with an offset. A silent stream with unsigned or
compressed samples mixed with another stream produces a clipped
stream. To hear the problem start QEMU with
qemu-system-x86_64 -accel kvm -smp 4 -m 4096 \
-audiodev pa,id=audio0,out.mixing-engine=off \
-machine pc,pcspk-audiodev=audio0 \
-device ich9-intel-hda -device hda-duplex,audiodev=audio0 \
-boot d -cdrom Fedora-Workstation-Live-x86_64-37-1.7.iso
on a host configured to use PipeWire and start audio playback on
the guest HDA device.
PA_SAMPLE_U8 is the only unsigned PulseAudio sample format.
There is no need to care about unsigned multi-byte formats.

When a stream uses the FIX_ flags it should negotiate to the format of
the sink or source it connects to. To do this, look up the sink or
source and look at the format, use this as the allowed format for the
stream when the FIX flags are set.
Make it still possible to override with with properties. Use
audio.position to make it possible to set a channelmap override.
Use a different key than the usual one to select an audio format when we
are fixating a stream format to avoid confusion.
So pulse.fix.rate, pulse.fix.format, pulse.fix.channels are now used to
force a specific format when the stream has the FIX_ stream flags.
Add support for using custom format, rate or channels when the streams
asks to fix those parameters for us.
Some streams might expect to see S16LE when they connect to a sink in
S16LE when the FIX_FORMAT flag is set but this is not the case in
PipeWire because the audio DSP pipeline works in F32, and so F32 is
choosen. Make it possible to use a pulse.rule with a audio.format
property to control this.
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.
The pulse API uses either the node.name or object.serials so pass this
along in the TARGET_OBJECT instead of the NODE_TARGET now that
wireplumber handles this.
