Instead of binding the socket to 0.0.0.0 with port 0, make some config
options source.ip and source.port to configure this. This makes it
possible to bind to other interfaces or to use a fixed port for the
data messages.
Fixes#4144
First try to parse the float value as a JSON number and then fall
back to atof to get the locale dependent variant.
This transparently makes things work with values such as 0.5 and 0,5.
Fixes#4234
Our current AES67 sender setup requires that that PTP driver drive the
entire graph. This adds support for allowing the AES67 RTP sink to be
driven by an arbitrary driver, while still using the PTP driver for
sending data on the network.
When aes67.driver-group is specified a pw_filter is created with no
ports, node.always-process = true and node.group set to the
aes67.driver-group. When set to PTP, this gives us process callbacks at
the PTP rate which we use to get the current PTP time in the RTP sender
by interpolating the clock snapshots from the pw-filter.

We allow a quantum of jitter in the write timestamp. The previous value
of 32 seems to be empirically determined, using the actual quantum
allows us to reason about this better.
When the combine-stream module is used as a source and the input streams
are overlapping, mix the samples instead of overwriting the previous
samples.

sndfile actually supports reading and writing from/to stdin/out with the -
filename, so allow that.
Add support for streaming in dsf, dff and midifile as well.
Add a -a option to pw-cat use a pipe with raw bytes, otherwise try to
use the parsers and sndfile to read/write from/to stdin/stdout.
You can then do things like:
sox 2L-053_04_stereo-DSD64.dff -t dsf - | pw-cat -pdv -
pw-cat 07.Joe.Satriani.Clouds.race.across.the.sky.wav | pw-cat -pv -
pw-cat -rmv --target=0 - | pw-mididump -
Fixes: #4204
Avoids need for additional configuration to allow disabling send (which
in turn was needed to avoid errors when a network interface is not
available on start).
In circumstances where the network interface is not ready yet,
creating a send socket will fail. This may be ok if we only
intend to use rtp-sap as a listener, therefore add an option for it.
Place the async state of the node in its activation.
Don't increment the pending state of the driver when an async node is
found because the async nodes will not trigger the driver when they
complete.
See !2104
`pw_link_info::error` was previously not cleared when a link was destroyed,
leading to a memory leak if an error message had been set. For example,
if format negotiation fails, and as a result the link is destroyed.
Don't schedule nodes that didn't receive us as the driver node yet
because they will not be able to signal us when they complete and leave
us xrun.
Also only count the nodes that we will actually schedule and expect a
signal from, set this in the pending activation counter. This can be
less when some nodes are still starting or receiving the driver
activation record.
This eleminates some errors when adding and removing nodes.
See #4182
Check if the node is FINISHED instead of checking the refcounts. It's
possible that the refcounts are 0 but the node was not scheduled or
finished yet.
If the node is not FINISHED but TRIGGERED, we can run the recover
without reporting an error.
Any other state is an error and we need to log this and recover.
See #4182
Use ATOMIC_LOAD to get status.
Debug the pending state after decrementing so we debug the value we
are actually going to test.
Add node id to debug lines to better track things.
Don't just overwrite the state with FINISHED but only do this when the
state was AWAKE.
The server might already have started a new cycle and placed
NOT_TRIGGERED as the state. Or, it might have changed the state to
INACTIVE. In all cases, we should not overwrite the state unless it was
AWAKE and we should only trigger peers when we were AWAKE.
This fixes some spurious xruns and glitches.
See #4182
When the queue is full, before this patch we used to go into usleep in
the hope that the other thread will run and empty the queue and that we
can retry after the usleep.
This however does not always work because the other thread might be waiting
for the thread that does the invoke call and we lock forever.
Therefore we should always try to make progress in some way. Instead of
waiting, allocate an (or use the previously allocated) overflow queue and
write to that one. We can chain multiple overflow queues together as many
as we need (but we might want to bound that as well).
The loop.retry-timeout property is now deprecated.
See #4114
We have various modules that set the priority higher than the dummy and
freewheel driver (ffado, netjack,...). This makes it impossible to use
the freewheel driver on them.
Use a memstream to collect the arguments so that it can dynamically
allocate as much memory as necessary.
Use a dynamic pod builder to construct the pods so that they can be of
arbitrary size.
Fixes#4166
Only set use the graph rate and duration when the ffado.sample-rate
and ffado.period-size properties are set to 0. Othersize use the
configure values.
Without this patch, it would just ignore the settings and always use the
graph rate.
Commit d04a28daef moved the configuration
of the IO_Position after we removed the node from the old driver but
forgot to move the code that updates the pending_state.
See #4094
Add a type to the events, which can be MIDI1 or UMP.
Add debug functions for UMP messages.
midifile only supports saving MIDI1 format files for now. It will convert
to MIDI1 when asked to write an UMP message.
In pw-cat, convert the MIDI1 messages to UMP before sending into the
graph.
Add OSC and UMP control types and make sure the mixer converts to the
selected format.
Mostly useful for legacy filters that use the old MIDI format, placing
the Midi control type in the format will make the mixer convert to it.
Make sure we clear IO_Buffers on the port and mixer before we clear the
buffers or the format. The IO_Buffer is used to check if the port should
be processed or not and its update is synchronized with the data-thread.
Set IO_Buffers on the mixer and node only after we have configured the
buffers on the node.
See #4094
