Add a new extension that can create a server on a user provided socket
with user provided security properties.
This is mainly used in flatpaks that want to create and bind a pipewire
socket with specific permissions for the flatpak app.
The flatpak will also provide an fd that will be closed when the server
can be removed.
Remove some of the hardcoded values (the absolute smallest buffer size,
independent on the sample rate) to a config option. Set it to the
default value of 4, like what it was before.
Change the hardcoded absolute lowest limit to 1 because anything else
does not make sense.
Enforce the quantum-floor when calculating the final graph quantum.
Fixes#3908
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
When the midi message does not fit in the current cycle, save it in a
buffer and send it in the next cycle.
Incomplete midi messages will be received in the next cycle and need to
be sent out at timestamp 0 of the cycle.
Detect dropped and incomplete messages and give a warning.
Try to close/open the ffado device when streaming_start() fails. This
seems to be the case after suspend/resume or a cable disconnect.
Unfortunately, ffado seems to be stuck in an unrecoverable state,
though, to make it really work...
Clean up port buffers when the filter is destroyed.
If ncurses is not initialized, then the global `LINES` variable stays 0.
This will cause problems because there is an unconditional `if (y > LINES)`
check when printing the driven nodes for a given driver node, resulting
in only the first one being printed.
Commit 71653e04d2 ("pw-top: add 'batch-mode' and iterations known from top")
that introduced batch mode missed this one condition, so fix that
by only checking the for terminal overflow in non-batch mode as
it is done a couple lines above.
Fixes#3899
`gst_caps_make_writable()` may create a copy which we have to keep
using afterwards. The return value was meant to be used for that,
but was promptly forgotten for the initial user.
Avoid such errors in the future by using an in-out parameter instead.
While on it, add a type check and remove a check for an impossible
condition.

gst-play uses autoaudiosink by default when playing audio, which
iterates over all sinks sorting them by rank. By default,
pipewiresink sets the rank to 0, but it can be overridden
by setting the GST_PLUGIN_FEATURE_RANK env. var. like this:
`GST_PLUGIN_FEATURE_RANK=pipewiresink:268 gst-play-1.0 /usr/share/sounds/alsa/test.wav`
But that doesn't work either because the autoaudiosink plugin also
filters the available options, testing for "Sink" and "Audio" to
appear in the classification metadata
(in the strstr comparison in
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/blob/main/subprojects/gst-plugins-good/gst/autodetect/gstautodetect.c?ref_type=heads#L220
klass is what's set by pipewire as classification,
self->type_klass is "Sink" and self->media_klass is "Audio")
Just adding the word Audio to the classification metadata fixes
this and allows pipewiresink to be selected by autoaudiosink.
I also set it in the source plugin since looking at the code,
autoaudiosrc works exactly the same.
The FFADO source needs to be the driver and the sink the follower so
that captured data can flow to playback without delay.
Instead of starting a new thread for FFADO, use a timer and the data
loop to wait for FFADO. This is not so nice because we do blocking waits
on the data thread but then we can schedule the source and sink without
a context switch from FFADO. We use a timer so that we can set a timeout
period before starting the graph and catch xruns. The timer will be
restarted immediately when the graph completes and we can go back into
the FFADO wait.
FFADO Xrun should result in a new wait() call.
Handle channels better, use AUX for the channels when they don't match
the given positions.
Silence playback when we don't have a sink or sink data.
Stop and start FFADO when the sink/source pause/resume.
PIPEWIRE_CONFIG_NAME=client-rt.conf pw-cli -m load-module
libpipewire-module-ffado-driver '{ ffado.period-size=32 ffado.period-num=2 }
now gives 4.722ms latency measured with jack_iodelay, equal to JACK.
See #3558
DMABuf caps without concrete formats and modifiers don't map well to the
Pipewire negotiation process.
Introduce a new gst_caps_sanitize() helper function, where such cases
can be handled.
Gstreamer 1.24 added and largely switched to a new, modifier aware
DMABuf API. Unfortunately that breaks the existing DMABuf support in the
PW Gst element.
Add support for the new API.
JACK current_msec can be in MONOTONIC_RAW or MONOTONIC, depending on how
JACK was compiled (but it's likely MONOTONIC_RAW). PipeWire requires the
nsec field to be in MONOTONIC so take some time snapshots from both
clocks and apply a translation.
Also make sure we only get the nsec time from streams that exist.
See #3886
Make a method to get the current time to compare agains the pw_time-now
field. This is currently CLOCK_MONOTONIC but make this into a method
so that we can more easily change it later.
When we disable autoconnect, disable the timeouts as well. Otherwise the
user has to connect the stream within the 30 second timeout or get a
failure. With autoconnect we can reasonably assume there is a problem
when the stream is not connected after 30 seconds.
Fixes#3884
node.sync-group can contain a list of strings. When a node in the graph
sets node.sync = true, it will be scheduled with all of the other nodes with
common node.sync-group strings. By default all nodes are placed in
group.sync.0 except the freewheel and dummy driver.
Use this to ensure that all nodes are grouped under the same driver
(that is not the freewheel and dummy driver) as soon as the transport is
started so that the transport is visible to all nodes from the same
sync-groups. We also don't deactive the sync-group anymore for the node,
even if the transport is stopped, to avoid driver changes and transport
jumps.
When the node that activated the sync/transport is destroyed, things are
restored to their original state. Note that this is different from JACK
where starting the transport outlives the application and always needs
to be explicitly stopped again. We can't really do this (by default) because
it leaves the graph in an unnatural state with all devices in sync.
The reason for the node.sync-group is that it is possible to still have N
different subgraphs with a separate transports by manually specifying
the node.sync-group.
It's also slightly different from the node.group, that is always active.
The sync-group is something you only want to enable in specific cases
because it groups drivers together and enables adaptive resampling etc.
It's also possible to place this option in the jack.conf file to
automatically sync all devices and apps as soon as a jack app is started.
Fixes#3850
The conf argument was unused before, but it is correctly populated
using the context's conf in pw_context_new(), so the code behaves
the same effectively.
This allows parsing standard conf sections from other configuration
sources, as long as the sections are placed in a dictionary.
Use `getaddrinfo` in `parse_address` instead of `inet_pton`.
Display Ipv6 addresses with scope identifiers correctly in `get_ip`
functions using `if_indextoname`.
We need to load and apply the overrides in the order:
If absolute config path, use only that.
If environment variable, use only that.
Else
/usr/share/pipewire/*.conf.d/
/etc/pipewire/*.conf.d/
$HOME/.config/pipewire/*.conf.d/
Before this patch we would first apply $HOME and then /etc and /usr,
which is not expected.
