Add an interface that can manager a dbus connection.
Make a dbus interface in the core that can create connections running
in the core main loop. Keep this as support for spa plugins.
Make a new PropInfo parameter that allows us to iterate all
properties. Make some new fields to set labels and names for
properties. We will be able to add more things to describe the
properties this way.
Use the Props param to simply query or set properties.
We can now make int enum properties and describe all possible
values with labels, we don't need to register types anymore.
This then makes it possible to enumerate the v4l2 controls and make
them available as control params.
Add an info property flag that should not be taken into account
when intersecting. We use this for docs and labels.
Improve builder, make it possible to make struct properties with
flags.
Add some docs to the property flags and ranges.
Add a permissions call that can be used to update the permissions
of global objects. This can be used to set specific permissions
on certain objects, hide objects and define the permissions on new
objects. The system is quite generic so that we can extend it later
with more complicated match rules or so.
List the factory interfaces that are provided.
The interface id of the typemap is always 0 to avoid the chicken and
the egg problem.
Check debug env variable
Don't recurse into the directory of systemd when it was not found.
There are still some issues because libudev is actually provided
by systemd these days and we still need that for building the v4l2 and
alsa monitors.
Add a check against letting the required number of ports become
negative for a node. With certain timing between the main and data
thread, this can otherwise happen.
For nodes where links are unlinked and relinked, a negative number may
mean that the scheduler skips the node and doesn't call
process_output().
Remove the per-port memory and only use per-node memory. This will
make it possible to share memory between ports in the future.
Keep refs to memory on the buffers and free (close) the memory
when no longer used.
The control values do not have to contain valid values when they
are set so don't try to parse them. Instead just do a simple sanity
check on the size.
Handle the case where we clear the io area, go back to the default
node properties.
Do not send the offset and size in the add_mem call, just send the
fd and the flags. The area that we need to map from this to find the
meta, chunk and data are sent in a separate call. This should make
it possible to truncate the memory to a larger size to dynamically
allocate more shared memory for a client.
Remove the Id data type, it's not needed.
Don't automatically map memory in remote.c
Pass the original memory type from server to client.
Handle DmaBuf mem in video-play now that the server passed it on.
Add control objects for all controllable properties on ports.
Try to link compatible control properties in autolink.
Allocate shared memory for the output property memory and configure
the io area on the ports when the controls are linked.
Send the shared memfd to clients when the io area is configured.
Add port_set_io support in remote.c, mmap the control io area and
set on the port.
Add some param helpers
Add volume control to export-source update the volume before
sending each buffer.
Make an int return from pw_node_for_each_port() so that we can return
errors or early exit.
Add pw_port_for_each_param() to iterate params. And use this to collect
the formats.
Reorganize the io parameter ids and objects. Make separate enumerations
for buffer, control, input and output properties.
Add a volume output property to export-source. This is still unused
but will eventually be routed to a PropsIn io area where it can
control the volume of a mixer, for example.
Make a method to find the memory block for the given ptr. We can
use this to find the memfd of the memory if there is any. We can
then remove the Shared metadata on buffers.
When the input port param enumeration has no result, use the NULL
filter to still enumerate the output port parameters instead of
returning nothing.
Fix the offset in the gst element.
Pass a spa_pod as the control io area. The pod is not supposed to
change in structure, only the values do so we can achieve the same
kind of performance as passing a single value but still allow for
more complex io area layouts to be passed later.
Add control properties to audiotestsrc for frequency and volume
and add a test program.
Add size parameter to set_io for additional checks and to make it
easy to know how much control data we can write.
Make it possible to configure multiple io areas on a port by giving
an id to set_io.
Add some types to enumerate the supported ids
Make an area to exchange buffers and one to specify pull ranges.
The idea is to make more area types for controlable properties.
Implement enumeration of IO areas in volume.
