The id is useless when dealing with props params, we need to use the
name of the property as the key. Also the id can clash with other ids
of other plugins.
Some follower nodes don't support all audioadapter params (For example, param
SPA_PARAM_Props is not supported by 'support.null-sink'). This change adds a
check to avoid unsuported errors when requesting a param that is not supported
by the follower.
Add PropInfo for all the params that we can configure at construct
time and also add them as PROP_params.
This way you can configure the headroom at runtime with this:
pw-cli s <id> Props '{ params = [ "api.alsa.headroom" 1024 ] }'
Expose the card object and always obtain one per pcm.
Keep the configured format in the card object.
Add a api.alsa.multi-rate property. When multi_rate is disabled,
only allow the last configured card rate on all PCMs.
This works around drivers that can't handle multiple samplerates
on their PCMs.
With this patch it should be mostly safe to configure multiple
sample rates in pipewire.conf

First check if the bluez dbus service is active before doing a
GetManagedObjects() call.
Else we might try to activate the bluetooth dbus service, which
should normally only be activated during bootup.
Scale the buffer size with the rate conversion ratio. Also make sure
that we can at least produce a maximum quantum of samples.
If we have large upconversion (8KH -> 48KHz) and small input
buffers, we would not allocate enough space for the output buffer
and cause xruns in the sink.
Fixes#1809
Simplify the key-value pair parsing for AT+IPHONEACCEV commands,
and move the handling of {key,indicator}-value pairs into
dedicated functions. Furthermore, fix a comment.
Keep track of the negotiated parameters and use those to construct
the Buffers param.
Use the FrameAllocator to allocate buffer memory. Keep a request for
each buffer and queue them.
In requestComplete, put the request metadata info into the buffer and
header and write the finished buffer id to a ringbuffer. Then wake up
the data thread to pop the finished buffer_id and push it in the
graph.
Remove some old files.
Instead of doing pointer arithmetic through actual pointers, cast them
to the proper integer types.
This is functionally equivalent to the previous code but is clearer for
the compiler.
Fixes#1018
The event is emitted by a node that is not a driver but wants the graph
to be scheduled. The command is sent to the driver and suggest that the
graph be scheduled.
The inotify_event field has a variable sized type, so it's recommended to store
it at the end of the storage unit. Fixes gnu-variable-sized-type-not-at-end warning.
