Ask RTKit what the min nice level is and clamp our value to it to avoid
InvalidArgument errors.
Also add some more info messages when the level is clamped or invalid.
Fixes#3186
For remote nodes, set the signal time before we wake up the server. For
non-remote nodes, ser the signal time in node_ready. This ensures we
take the time to start the graph into account.
Use separate flag for indicating if pw_stream_destroy is needed.
Don't set s->stream = NULL to indicate that, it will race with data
loop. Setting to null separately is not needed, removing from the stream
list is enough.
Add a _fast callback function that skips the version and method check.
We can use this in places where performance is critical when we do the
check out of the critical loops.
Make all system methods _fast calls. We expect them to exist and have
the right version. If we add new versions we can make them slow.
This way we can search for the real jack library instead of using our
custom libjack.so. Add an option to override the search path with
LIBJACK_PATH and an option to select the library name to load.
Set the module to NULL when unloading. Check if the module exists before
attempting to unload it.
Flush any pending invokes on the mainloop before destroying the impl.
Fixes#3199
Make a new method to parse parts of the audioinfo based on custom
keys, leaving unparsed values to defaults. Implement the generic audio
parsing with this.
We can then remove some duplicate code where the audio keys didn't match
or where only parts of the info needed to be parsed.
Also make a method to serialize the audioinfo to properties and use that
when making arguments to load the modules.
Avoid doing some custom property serialization, move all key/values into
properties and serialize those with the generic functions.
It is possible that we destroyed the source/sink when we get a latency
update from jack, don't try to update the source/sink in that case or
we will crash.
Let the server calculate signal time when it starts the graph. Otherwise
we overwrite old values and we can't do stats.
We might be able to piggyback the signal time in the prev_signal_time
field later.
Don't make an extra eventfd for activating the remote-node, we can
use the server side eventfd and send them to the remote side using
the transport.
The remote node already adds the eventfd to the data-loop so avoids
doing the same on the server.
This makes driver nodes trigger all remote nodes directly instead of
going through an intermediate eventfd. For resuming nodes, we already
used the node eventfd directly so this only a small optimization
for the initial cycle start.
Add latencyOffsetNsec prop to the combine node.
This is mainly useful for BAP device sets; the property appears in
Pulseaudio UI only when the node is associated with a device.
For client-nodes that use trigger, set the signal and wakeup time when
they start the server node. Also set finish time before we resume the
peers on the server.
Client-nodes should really resume the peers directly without going
through the server but this is something to improve later.
Currently, RAOP sinks referencing the same remote ip and port may be created multiple times:
One each for IPv4 and IPv6, times the number of network interfaces used for mDNS discovery.
A recent change added `(IPv4)`and `(IPv6)`identifiers to the sinks' pretty names, however that
is misleading, as often times the service advertised through an mDNSv6 record is actually an
IPv4 service (i.e. the IP reference contained in the IPv6 record may be an IPv4 address).
With this change, sink creation is skipped if a sink with the same advertised name already exists.
Determine application executable file so that the result can be trusted,
and the file exists in the current namespace.
Don't use /proc/pid/cmdline, since that contains whatever was specified
by the exec() call.
Stop our own data-loop and enter/iterate/leave it from the jack thread.
This runs all our nodes in the JACK thread and removes 2 context
switches (jack to and from pw thread).
We can possibly do this nicer by only pushing our own streams onto a
new custom data-loop but that's for later.
Add a new JACK sink/source pair that translates to a single JACK
client.
The JACK playback port appears as PipeWire source and is processed
directly, synchronously, through the complete pipewire graph into
the PipeWire sink that is then made available on the JACK capture
ports.
Because all this happens in the same JACK cycle with no delay, the
latency is 0. A jack_iodelay on the JACK server has exactly the same
latency as the jack_iodelay on the PipeWire side.
The PipeWire sink and source are forced into the same rate and
buffer_size as the JACK server and can't dynamically change.
This only supports Audio for now.
When we consumed all the buffer data, don't clear all the fds but only
those that were already consumed in the message. It is possible that we
already have fds for the next message and we don't want to discard
those.
Fixes some intermittend memory map errors.
Calculate the stats at the start of the new cycle. The results will be
about the previous cycle but this gives more accurate results because
we can also include awake and finish times of remote nodes.
Make sure not to change the status of the activation in the ready event
so that we don't overwrite the status of the last cycle yet.
This means we can always set the AWAKE and awake_time, the remote node
might update it when triggered but that's ok.
After processing we can update the FINISHED state for non-remote nodes,
the remote nodes will update it after they complete the process
function.
Pass the ready status to the client-node using the state array.
Don't just SPA_STATUS_HAVE_DATA on the server side but use the value
from the client.
This avoids some potential extra work when a driver sink pulls in data
with the NEED_DATA ready callback but then the server performs the
actions (tee) as if it were SPA_STATUS_HAVE_DATA.
