When the stream requests a 0 size buffer, don't start the drain but
simply queue a 0 size buffer.
Sometimes, switching quantums and drivers might request a 0 buffer
async and this should not cause a drain operation.
Deprecate pw_stream_get_time() in favour of _get_time_n() that contains
the size of the pw_time structure. Make the old one fill in the fields
up to the buffered field. Make the new one use the size to decide how
much info to fill in.
Add a new buffered field in pw_time that contains the buffered data
inside the converter/resampler. This leaves the queued field with
purely the user provided size in the buffers.
Use get_time_n() in places.
Library code generally shouldn't modify global state, so pw_init()
should not result to changing the C locale.
Instead, set the C locale in main() for tools and daemons.
We'll still setlocale for LC_MESSAGES, to get translated UI elements in
wireplumber. This workaround should be removed eventually...
Make all tools output to stdout (pw-mon mostly) so that we can pipe the
output around.
Send errors to stderr.
fprintf(stdout, ...) -> printf(...)
setlinebuf for stdout so that pipe works better.
See #2110
Mark some structures, arrays static/const at various places.
In some cases this prevents unnecessary initialization
when a function is entered.
All in all, the text segments across all shared
libraries are reduced by about 2 KiB. However,
the total size increases by about 2 KiB as well.
This also brings the advantage that all tools, examples, modules, components
can also be compiled standalone out-of-tree using libpipewire from the system
Just like the real free() we should just ignore a NULL pointer, makes the
caller code easier for those instances where properties are optional.
Patch generated with concinelle with a few manual fixes.
Don't just store the id in the metadata but a JSON object with
the node name. This makes it possible to easily introspect the
metadata and also extend the metadata with more fields later.
Instead of matching the metadata id to the global ids we now
have to match it against the name.
Make methods to load_config and load/save state. For now the config
and state directories are the same but it might not be. Implement
the search path for all config/state files as:
$XDG_CONFIG_HOME/[$prefix]/$name
$HOME/.config/[$prefix]/$name
$PIPEWIRE_CONFIG_DIR/pipewire/[$prefix]/$name
/etc/pipewire/[$prefix]/$name
Make some config files for jack and RT clients. Make pw-cat use the
client-rt config.
Use core state and config management in media-session.
Move all session manager state and config files to the build dir and
set the PIPEWIRE_CONFIG_DIR to this build dir.
