Make a new DRAINED status.
Place the DRAINED status on an input IO when a stream is out of
buffers and draining.
All nodes that don't have HAVE_DATA on the input io need to copy
it to the output io and return the status. This makes sure the
DRAINED is forwarded and nodes return DRAINED from _process()
DRAINED on the resampler flushes out the last queued samples and then
forwards the DRAINED in the next iteration.
Emit a new drained signal from the context when a node returns
DRAINED. Use this to trigger the drained signal in the stream.
Always take the state of the builder to get the newly filtered
object, even in the case there is no filter.
Handle the case where we can't copy the pod in the case of
a NULL filter by reverting the state of the builder.
Rework the function a bit to make it possible to pass a NULL
result (to calculate the required size, for example)
Fixes#226
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.
The choice array might have excess elements when the type has been
changed, for example by fixation. This is not a problem and the
excess elements should simply be ignored.
Using the short name of a type without the base part is common enough
that a common utility method is warranted.

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.
So that we can check for negative value.
Also don't signal incomplete graph when we signaled more than
expected, this can happen when we add new nodes in the current
cycle and then triggered the driver.
Add a asprintf helper function that handles errors correctly.
Use this in places where we use asprintf to avoid warnings when we
don't check the return value.
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.
If an ID cannot be de-referenced, e.g., because the builder buffer is
too small, spa_pod_filter() still reports success, but the result is
NULL. Any subsequent access to result will cause a segfault.
Return an error if no pod is found to properly propagate and handle the
error.
The segfault can be reproduced by using the v4l2 module with Vivid
devices [0], because the buffer for the v4l2 controls is too small.

This is more in line with wayland and it allows us to create new
interfaces in modules without having to add anything to the type
enum. It also removes some lookups to map type_id to readable
name in debug.
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.
