We now automatically move non-rt clients into non-rt threads so the
client-rt.conf is obsolete.
Move the module-rt in client.conf and add conditions to disable modules.
Transparently load client.conf in case applications still specify
client-rt.conf.
Custon configuration in the client-rt.conf.d/ should be moved to
client.conf.d/
The src can listen to RequestProcess commands and so gets the
node.supports-request = 1 property.
The play-pull example can both be a driver that listens to
RequestProcess or a lazy driver so set this in properties as well.
We can now remove the priority.driver property because automatic
priority selection will make us a driver or not.
With this change, video-src to video-play-pull will use lazy scheduling
with play-pull as the driver. video-play-pull to v4l2src will use
normal scheduling and video-src to video-play will also use normal
scheduling.
The mapoffset should be using in the mmap call as the offset.
Mapping the whole memory before the offset and then ignoring the part
before it seems like it can work but it actually has some problems:
1. some drivers (v4l2) use the mapoffset to calculate the buffer to map
2. we waste resources for mapped but unused pages.
The problem with the mapoffset is that it needs to be page aligned and
that used to be a problem in the past. Nowadays PipeWire no longer set
the mapoffset for any of the memory that it allocates.
Make a method to get the current time to compare agains the pw_time-now
field. This is currently CLOCK_MONOTONIC but make this into a method
so that we can more easily change it later.
Whe using pw_*_new_simple(), pass the properties to the automatically
created context as well so that we can configure it.
This makes it possible to, for example, load the client-rf.conf using the
simple API as well.
In bluez5-dbus.c:impl_init, the info is passed to spa_bt_quirks_create,
which expects info to be non-null. But in this example, info is null, so
it will cause quirk table parse failure. Add an empty dict here to prevent
this error.
The tag param has a list of arbitrary key/value pairs. Like the Latency
param, it travels up and downstream. Mixers will append the info
dictionaries or do some more fancy merging.
The purpose is to transport arbirary metadata, out-of-band, through the
graph and it's used for stream metadata and other stream properties.
this event extends the bound_id event and sends the global properties as
well.
This can be used to get the object.serial, for example.
It can also be used in the future to let the server generate unique
property values, like the node.name, and let the client know about the
new property value.
Use the new requested buffer field to only queue the amount of samples
required by the resampler for the current quantum. This avoid spikes
when the maxsize block of samples is processed.
Fixes#2353
Make the alignment parameter optional when negotiating buffers.
Default to a 16 bytes alignment and adjust for the max cpu
alignment.
Remove the useless align buffer parameter in plugins, we always
set it to 16 anyway.
The posibility to drop single modifier was added in this development
circle (after 0.3.39 release). To have clients work with older versions
of PipeWire dropping all modifiers can be an option.
