The PropInfo either has a registered id (and then also a name from the
type-info) or a custom name as a string.
In all cases, the description contains a free form text that clarifies
the property.
Use the description in the stream controls name.
For the modules that require a driver, don't add ourselves to
the pipewire.dummy group but instead just use the NODE_WANT_DRIVER
property to be assigned to a driver.
This makes it possible for the nodes to move to another driver than the
dummy driver (which has very high priority) and it avoids resampling in
cases where the nodes are linked to an audio source or sink.
Only make the driver node active when we assign it an always_process
node. Otherwise we can keep the driver passive until some other active
nodes are added.
Fixes a case where an need_driver node would automatically activate
the driver, even when nothing is to be scheduled.
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.
Make a custom thread_utils that can use the configured global
thread creator and set this in the data-loop.
This ensure that the data loop uses the creator thread when activated.
See #1495
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.
We are really interested in the error code of the statements we queued
before the sync so clear any previous error first. Otherwise we might
pick up a previous random error, which never gets cleared.
See #1714
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
