JACK can handle 2 buffers at most, make the default buffer allocator
allocate 2 buffers when no params are given.
Prefer 2 buffers, it allows some form of async fill/consume
When we finished processing the history it might be possible that we
need to skip some samples from the input. Implement this by adding
a start offset for the samples in the buffer.
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
We can produce data whenever the io area status != HAVE_DATA. We
don't need to look for NEED_DATA.
Also recycling buffer happens whenever the status != HAVE_DATA.
Example executable that runs an output audioadapter using audiotestsrc as slave
with an input audioadapter using alsa-pcm-sink as slave for easy testing.
The example-control executable does not play audio. This is because
alsa-pcm-sink needs a data system to run. This patch fixes the example by
loading a data system from libspa-support before creating the nodes.
If the target node is set to 0, remove the autoconnect flag. This makes
the session manager disable stream autoconnect and some other program
needs to connect the stream to a sink or node.
Use the channelmap from the file, if available.
Add option to specify/override the channel map for playback.
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.
The card name (id) can be configured with udev rules to remain
constant based on where the device is plugged in even when there
mulitple of the same devices.
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.
Add an option to allow the user to disable examples, this will allow to
build pipewire without alsa. Without this option, build with
-Dpipewire-alsa=false -Dalsa=false fails on:
src/examples/meson.build:47:0: ERROR: Unknown variable "alsa_dep".
