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.
The current implementation assumes these are mutually exclusive, but
Yamaha MusicCast requires an auth-setup step following the digest
authentication.
`rtsp_auth_reply` could be dropped in favour of `rtsp_options_reply`,
but you may end up in a loop if the other end keeps responding with 401.
Yamaha MusicCast (or at least the RX-A880) seems to be stricter about
the URI here, as it rejects `*`. Examples, such as those documented by
OpenAirplay, use the real URI.
Clang 15 at least with my build configuration emits warnings about
function prototypes that lack argument types. Most notably this
happens with functions that take no arguments which in compiler view
equates to the void type i.e. void f(void) instead of void f(). As I
understand, this will become an error in some future Clang release,
so might as well fix it now.
Since these were discovered not by a linter but by the actual compiler
for my particular build configuration, some f() may have escaped for
now. But at least it's enough to build PipeWire with most optional
features enabled even when -Werror=strict-prototypes is enabled.
For anyone else wanting to have a go at this, these can be upgraded
from warnings to errors by adding -Werror=strict-prototypes to the
custom CFLAGS which probably works with GCC, too, but has only been
done with Clang 15.0.2.
Finally my editor automatically stripped trailing spaces upon saving
the modified files. I assume it's probably not worth keeping those
invisible bytes around but this may have slightly dubious implications
as it did also turn indented empty lines of JACK license header into
regular empty lines.
