When we are not working RT, only request a buffer when we recycled one
or when we had no buffers in the queue.
The reason is that we only want to request a new buffer when the
converter recycled a buffer and thus when the resampler has a new
input size suggestion.
We also want to request a new buffer when there is no new buffer to
queue. This would be an underrun but we need to keep on requesting
buffers in this case or else we stall forever.
Keep a counter for the amount of times pw_init() was called and
only clear everything when pw_deinit() was called an equal amount of
times.
Also ensure that pw_init() can be called again after pw_deinit().
Fixes#2238
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...
This mode allows using a json file generated by pw-dump as input,
in order to visualize it.
Example usage:
pw-dump > dump.json
pw-dot -j dump.json -sL
This enables developers to easily visualize user dumps and at liberty switch
visualization modes (all, smart, detail, etc) without requiring the user
to do anything except for generating the initial dump.
And use this in spa_json_format_float() where we also avoid invalid
json floats.
Use json float format in some places where we serialize json floats.
Add a unit test.
See #2223
After dequeueing the buffer, the code immediately checks if it is NULL,
and never modifies the variable. Therefore there is no need to check
again when the buffer is enqueued.
Add a property to select the upmix method. PSD is enabled by default
but a new simple upmixing algorithm is available that duplicates
channels and avoids lowpass filter on the FC and disables widening.
Fixes#861
Support setting extra properties on the sink and source with the
sink/source_properties.
Fix construction of the module arguments, the sink/source.props needs to
be inside the object..
Fixes #2201
When a particular AvahiWatch is being dispatched, it cannot
be freed because `watch_callback()` accesses it after
the callback.
Introduce a member (`dispatching`) to coordinate
the deferred freeing in that case.
The timeouts are not affected because the `AvahiTimeout`
object is not accessed after the callback is called.
Use target-object=<serial/name> instead of path=<id> for specifying
sink/src targets. Deprecate path= argument.
Change device provider to preferably expose serials instead of ids.
In a dynamic builder we can only save the offsets in the array and
deref after we completed building everything.
Increase the control limits.
See #2179
Resizes the buffer dynamically. Be careful with getting the address
of a pod in the buffer, it might not be valid after building more stuff
with the builder.
Add an option to do a hilbert transform on the generated rear channels
to do a 90 degree pahse shift on them. This can improve spacialization
of the rear channels.
See #861
