Add jack.connect-audio and jack.connect-midi to specify an array of port
names to link to instead of the default phyisical ports.
Also actually fixes linking the midi ports correctly.
Take the current cycle times early and in all cases. We can use this to
get the current frame time for debugging purposes instead of the more
heavy jack_frame_time().
Rate limit the xrun warnings.
Make a function that can initialize raw audio info from a dict and fill
in the defaults. We can use this in many of the modules when the audio
format is parsed.
Use the helper instead of duplicating the same code.
Also add some helpers to parse a json array of uint32_t
Move some functions to convert between type name and id.
Add spa_json_begin_array/object to replace
spa_json_init+spa_json_begin_array/object
This function is better because it does not waste a useless spa_json
structure as an iterator. The relaxed versions also error out when the
container is mismatched because parsing a mismatched container is not
going to give any results anyway.
Unloading the module on stream errors is a bit too much because a
suspend can clear the stream error again (or the error might not be
fatal)
This can happen for example when negotiation fails on some stream ports
(wireplumber tries to link the midi ports to audio ports) and it's
better to not completely fail on that.
Fixes#4121
JACK current_msec can be in MONOTONIC_RAW or MONOTONIC, depending on how
JACK was compiled (but it's likely MONOTONIC_RAW). PipeWire requires the
nsec field to be in MONOTONIC so take some time snapshots from both
clocks and apply a translation.
Also make sure we only get the nsec time from streams that exist.
See #3886
Remove some includes of private.h
Add some methods to get the mempool of client and context so that we can
remove direct access.
Move some things around.
Use methods to get pw_loop variables.
See #3243
Our sink and source callbacks are called twice, once when the graph
starts and once when it completes, make sure we don't signal the jack
graph twice or we get corrupted output.
Fixes#3255
This way we can search for the real jack library instead of using our
custom libjack.so. Add an option to override the search path with
LIBJACK_PATH and an option to select the library name to load.
It is possible that we destroyed the source/sink when we get a latency
update from jack, don't try to update the source/sink in that case or
we will crash.
Stop our own data-loop and enter/iterate/leave it from the jack thread.
This runs all our nodes in the JACK thread and removes 2 context
switches (jack to and from pw thread).
We can possibly do this nicer by only pushing our own streams onto a
new custom data-loop but that's for later.
Add a new JACK sink/source pair that translates to a single JACK
client.
The JACK playback port appears as PipeWire source and is processed
directly, synchronously, through the complete pipewire graph into
the PipeWire sink that is then made available on the JACK capture
ports.
Because all this happens in the same JACK cycle with no delay, the
latency is 0. A jack_iodelay on the JACK server has exactly the same
latency as the jack_iodelay on the PipeWire side.
The PipeWire sink and source are forced into the same rate and
buffer_size as the JACK server and can't dynamically change.
This only supports Audio for now.
