Add some padding to the delay buffer. If we wrap around, copy the
spilled samples to the front of the buffer. This makes it possible to
use the more optimized sse delay function in more cases.
In our current world, it is possible to have a negative delay. This
means that the stream should be delayed to sync with other streams.
The pulse-server sets negative delay and the Latency message can hold
those negative values so make sure we handle them in the helper
functions as well.
Do the delay calculations in pw_stream and JACK with signed values to
correctly handle negative values. Clamp JACK latency range to 0 because
negative latency is not supported in JACK.
We should also probably make sure we never end up with negative
latency, mostly in ALSA when we set a Latency offset, but that is
another detail.
So that a config override can disable the execution of the command by
setting the property to false in the pulse.properties config override.
Expose some conf.c method for this purpose.
Add support for some modules to use a module.$NAME.args config section
to override the arguments of the module. Update the docs.
Add more conditions to the module loading, use !false to also load the
module when the condition is not set and so that we don't have to
explicitly set each condition to true.
Improve module-profiler example config.
Make the xrun reporting as info. This can generate a lot of logging if
the error is persistent and the errors are also reported in pw-top etc.
Fixes#4361
The loop in the TSS gets an extra refcount and is unreffed when the TSS
destroy is called.
We can then also ref the queue during the function callback. When the
queue (thread) was destroyed during the callback, ignore the result and
continue with the next queues.
See #4356
When we clear we need to have all our queues removed from the TSS when
we delete the tss key or else they are leaked, check an warn about this
using a refcount of queued in the TSS.
See #4356
Make it possible to call loop_queue_destroy() from both the TSS destroy
and impl_clear() without races. We make sure that only one can remove
the queue from the queue list and cleanup. We also store the IN_TSS flag
in the flags so that we can see them before the queue is added to the
queue list. Only free the IN_TSS queue when the TSS destroy is called.
See #4356
Similarly as in spa_dbus, don't exit if bus goes down. Neither the
audio or midi Bluetooth backend reconnects to DBus, but they shouldn't
exit the process.
The convolver will parse integers as a sample delay (as before) but will
now also fall back to parsing it as a float in the time domain.
Specifying the delay in time is better because it does not depend on the
samplerate of the graph or the IR.
Store the biquad type in the biquad, remove some unused fields.
Init all the biquads with the identify before loading the channel
specific biquads. We will process the max of all the channel biquads.
Make sure we skip processing for the indentity ones.
Use a wrap around delay ringbuffer. We can then avoid some modulo
arithmetic and read more efficiently.
Also handle the delay convolver case better by reversing the taps and
reading the taps and delay buffer without extra overhead.
When we allocate data on an output port, always set it immediately on
the plugin. We let output nodes allocate data and input ports consume
it.
When we have no data on an output port, use discard data or NULL.
This ensure that the ports only have data when they are used by an input
port and otherwise use discards or NULL data.
Add sse optimized biquads.
Make a new dsp function to run multiple biquads on multiple channels.
This makes it possible to unroll some operations and run the channels
in parallel later.
Simply load a filter-chain with the new param_eq node and the
given filename in the config.
This fixes a number of issues such as not copying global properties to the
streams, setting a unique node.name etc...
