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.
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
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.
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.
