We don't need to pass the client to the module create and load
functions, they can work without a client.
The only place the client is used is to access the properties to make a
new connection to pipewire. This is also however not a good idea, we
should simply use the defaults used by the context or else a client
could set strange properties like remote.name etc for these internal
connections.
Also removing the dependency of the client will make it possible to load
modules from the startup script or other modules later.
First set some of the port flags and data, especially the owner_data
before calling pw_impl_port_set_mix(), which will use the owner_data
to send the mix_info.
See #2847
We don't always need to send buffers to a remote port, when the port
is an output port, all the mix ports use the same buffers. This means
that when we add another link to a port, we don't get the mix_info
anymore and then we don't know the peer_id and we don't complete the
link and we don't call the connection_callback.
Instead, send the mix_info right before sending the Buffer Io area. We
always do this for all mix io and after we have sent the buffers so this
is a better place.
Fixes#2841
When a client is not sending any data when it should be and causes an
underrun, mark it as idle and record the timestamp.
When a client is idle for pulse.idle.timeout seconds, set the stream
as inactive. When more data is received, set it back to active.
Add a pulse.idle.timeout option to set a global server default or
a per-stream value. Set the server default to 5 seconds. A value of 0
can be used to disable this feature.
With this change, badly behaving clients that are not sending any data
will be paused so that the sinks can suspend to save battery power.
Fixes#2839
Make a method to pause and resume a stream and keep track of the paused
state of the stream. Use this function instead of setting the stream
inactive/active so that we get nice logging for each state change.
When a server is started, try to publish the pending services.
When a server is stopped, republish the services.
This makes it possible to load and unload the tcp protocol after loading
the zeroconf publish module and it will do the right thing.
Loop over the servers and use its family and port to publish the
zeroconf services.
This avoids exposing the services when we don't have any TCP servers
running to accept connections.
It also avoids exposing the services twice with both IP4 and IP6
addresses.
It also exposes the services with a port that is actually usable, in
case it's not the same as the default port.
The monitor mode does not create a echo-cancel-playback node, and makes the
echo-cancel-sink node to be a monitor node with media class Stream/Input/Audio
(instead of Audio/Sink).
Some applications get confused when their output stream node is not linked
directly to the actual device node. Having echo-cancel-sink as a monitor node
avoids this problem, allowing those applications to work properly even if echo
cancel is enabled.
This mode is disabled by default. You can enable it by passing the specific
option (monitor.mode = true) in the args when loading the module in the
pipewire context.modules configuration section.
Just like the optional build, make all field parsing optional. This
will leave the fields with their default values if they are not parsed
from the param.
We can then remove our custom functions and use the generic ones in
various places.
Add a new seq field in the param-info struct. Users can use this
field to keep track of pending param updates.
Store the latest seq number of the param update in the seq field. Remove
all params that don't match the sequence number because they are too
old. This avoids duplicate old params in pw-dump output.
Rework the pulseaudio manager with this same method.
Make it possible for a aec-plugin to provide props/params
through module-echo-cancel and make it possible for a
aec-plugin to listen and react to these props/params getting updated.
Add method enum_props() that is used under setup_streams() to
get props from aec_plugin.
Add get_params() and set_params() for updating and getting
aec-plugin params under the input/output_param_changed calls
and getting params under setup_streams().
Do not use old delayed data in play_buffer when a new stream is started.
Copy silence to output until play_buffer has been filled with new data
instead.
Add a target.delay.sec property to module-loopback that uses a
ringbuffer to further delay the signal to the requested value. This
also takes into account the graph delay to get an end-to-end delay.
Add a -d property to pw-loopback to control this.
Implement latency_msec on the pulse module with this new property so
that it behaves similar to pulseaudio.
Pulseaudio requires that we call pa_stream_write with a multiple
of frame_size bytes. Because our ringbuffer is a power of two, this
might cause problems at the edge of ringbuffer where a sample is
split between the end and beginning of the ringbuffer.
Avoid this by letting pulse allocate a buffer instead and memcpy
the requires samples into it.
Fixes multichannel output on module-pulse-tunnel.
