The conf argument was unused before, but it is correctly populated
using the context's conf in pw_context_new(), so the code behaves
the same effectively.
This allows parsing standard conf sections from other configuration
sources, as long as the sections are placed in a dictionary.
Use `getaddrinfo` in `parse_address` instead of `inet_pton`.
Display Ipv6 addresses with scope identifiers correctly in `get_ip`
functions using `if_indextoname`.
Add some option to set manually group IDs of unicast streams
of devices.
Intel controllers don't appear to support more than one group at a time,
but in principle this can be done.
Keep track of the active number of mixer ports and update the global mix
io in sync with the data thread because that is where we will check the
state of the global mix io.
This is mostly important for output ports. When removing all links from
an output port, we first will clear all the mixer io and then remove the
global mixer with client_node_port_set_mix_info(). If we don't clear the
io before that, the data thread will be using that buffers as they are
cleared.
See !1915
When we clear the port io, pause the core until the invoke call
completed. This way we don't start processing other messages until we
have safely removed the port io.
Normally, when clearing a link on a port, first the mix io will be set
to NULL and then the format will be cleared, which clears the buffers
as well. By delaying the processing of the format clear until the io
is removed from the data thread we avoid taking away the buffer memory
from the processing thread prematurely.
When creating a link, first the format and buffers are configured and
then the io is set, which should be safe in all cases.
See !1915
Propagate the error if spa_system_eventfd_create() fails. Also copy
errno before calling spa_log_debug() in spa_system_eventfd_create() to
make sure it is not overwritten.
Fix some copypaste mistakes and other errors.
Add explanations for some more properties. Explain "drop-in" config
files. Explain filter-chain.conf.
Move configuration man pages under Configuration in TOC.
Add reference documentation for configuration settings & node/device
properties. We should have boring & exhaustive reference lists of all
the options, and an index where they can be looked up as needed.
The content is mostly stolen from the Wiki.
Add pipewire-client.conf.5, pipewire-jack.conf.5, and pipewire-device.7
that try to explain all available configuration settings for native/ALSA/JACK
clients, and parameters & properties devices.
Expand pipewire.conf.5 and pipewire-pulse.conf.5 with lists of supported
properties. Also explain environment variables.
Doxygen doesn't have an indexing mechanism suitable for configuration
settings, so add a simple one using an input filter and use it here.
Tweak styling a bit.
The rate we get from dlls can have a subsample precision. However,
the check for using process_copy is in sample precision. This means
that an adaptive stream will oscillate rather then lock into the
exact rate.
We need to load and apply the overrides in the order:
If absolute config path, use only that.
If environment variable, use only that.
Else
/usr/share/pipewire/*.conf.d/
/etc/pipewire/*.conf.d/
$HOME/.config/pipewire/*.conf.d/
Before this patch we would first apply $HOME and then /etc and /usr,
which is not expected.
