Add the list of possible ports for a device.
Pass the allowed devices in the routes.
Store the active port in the device.
Fixes enumeration of ports on devices with UCM.
Add a READONLY property flag to makr properties READONLY
Set the base_volume and volume_step in the acp device
Send the base volume and step as REAONLY properties. Use these
in pulse layer.
The dataType parameter is a bitmask of allowed data types for the
buffer memory. Make the mask by or-ing all (1 << enum spa_data_type)
you accept/produce.
The this field can be used by apps who keep a copy of the
spa_param_info. They can use it, for example, to keep a counter
with the amount of changes since last processed.
Make channel layout definitions a little more useful. We can now
assign them to a layout_info struct or in the raw_info.
Make some default channel layouts for use in pw-cat
Add Profiler object and fields.
Add profiler extension API. It notifies Profiler objects with
real-time performance data.
Add module that implements the profiler extension.
Add pw-profiler tool that binds to the profiler API and dumps the
data into a log file, gnuplot files, a html page and a script to
generate svg graphs. This is almost the same as what JACK2
JackEngineProfiling does.
Use the DSP media subtype to describe DSP formats. DSP formats
don't include the rate, channels and channel position in the
format and must use the rate and duration from the position io. This
makes it possible to later change the samplerate dynamically without
having to renegotiate the graph.
The same goes for the video DSP format, which uses the io_video_size
from the io_position to get the size/stride. Set this up in the node
based on the defaults from the context.
Make it possible to define defaults in the daemon config file, such
as samplerate, quantum, video size and framerate. This is stored in
the context and used for the DSP formats.
pulseaudio card is mapped to device
pulseaudio sink/source is mapped to an endpoint
prepare to map streams to card profiles
Add Route param to implement the endpoint routing later (ports)
Create an alsa endpoint for each device
Create one stream for each endpoint (Playback/Capture)
Implement create_link on the endpoint. The idea is to call
create link on the peer endpoint to complete the link. Remove
create_link on the session.
Add stream-monitor to turn pw_stream nodes into endpoints
Add a policy manager that tries to link endpoints
Use enum pw_direction for the endpoint direction. We can use the
media_class to determine if this is a pw_stream or not but it should
not really matter, you can link any output to any input.
Add autoconnect property for endpoints to make the policy connect.
Add a new PortConfig parameter to configure ports of elements that
are marked with the SPA_NODE_FLAG_*_PORT_CONFIG. This is used to
configure the operation of the audioconver/audioadapter nodes and
how it should convert the internal format. We want to use the
Profile parameter only for cases where there is an enumeration of
values, like with device configuration.
Add unit tests for audioconvert and adapter to check if they handle
PortConfig correctly.
Make the media session use the PortConfig to dynamically configure
the device nodes.
Remove audio-dsp, it is not used anymore and can/should be implemented
with a simple audioconvert spa node now and some PortConfig.
Add a new struct spa_param_info that lists the available params on
a node/port and if they are readable/writable/updated. We can use
this to replace and improve the PARAM_List and also to notify
property change and updates.
Update elements and code to deal with this new param stuff. Add
port and node info to most elements and signal changes.
Use async enum_params in -inspect and use the param info to know
which ones to enumerate.
Use the port info to know what parameters to update in the
remote-node.
Remove the spa_pod_iter helpers
Remove builder/parser vararg recurse option, you have to
manually recurse into structures when needed. This simplifies
things a lot.
Pass spa_pod_frames to builder and parser explicitly, we don't
have to keep an internal stack anymore.
The parser is now almost a mirror image of the builder.
Make the parser safer when iterating over objects, add functions
to check and get pod contents in a safe way.
Make the builder return errno style results on errors
Improve performance of object properties when they are stored and
retrieved in the same order.
Add many more tests for the builder and parser
Add some benchmarks
Automatically parse and build key/value when in objects without having
to prefix the key with ":"
Automatically build control/value when in sequence without the "."
prefix.
Remove the builder with key/pod, taking a reference to the stack built
temporary pods is not allowed in c++. We can use the varargs version
with the same convenient syntax.
Remove the parser "*" option, it is unused.
Improve spa_pod_builder_add_* and spa_pod_parser_get_* and make them
look similar.
