When the stream has more channels than the filter inputs or outputs,
don't try to connect an invalid filter port but ignore the input and
clear the output.
pthread_getschedparam() always returns non-negative values, so checking
if its return value is less than zero always evaluates to false.
Also, pthread functions don't set errno. While logging a warning
message, use the return value of pthread_getschedparam() instead of
errno.
First go over all the input and collect pointers and the size that we
need to copy. Then go over all destinations and copy the source or
clear the buffer memory.
This fixes the problem where extra planes in the destination would get
a 0 size, which would make the converter produce 0 output. It also
ensure that the output size is consistent.
Add in input/output stream, setup the talker/listeners.
Implement IEC61883 audio packets, send and receive data.
Implement talker encoding.
With this, audio can be sent and received from MOTU M64.
Join a READY listener MRP attribute when we recveive the transmit
response.
Also listen for talker attributes.
Remove attribute callbacks, we don't need them because we moved the
packet construction in the MRP users.
Implement notify for listener attributes.
A connect will now make my MOTU send samples to PipeWire.
Remove some of the json parsing for now, work with descriptors.
Remove some parsing code.
Implement GET_AVB_INFO.
Keep descriptors in a list.
Add some utils.
Listen to all messages. We don't seem to receive TSN messages from our
local host it seems.
Reply with not-implemented for an AEM_COMMANDS.
Implement some mode ADP messages.
The default metadata update may be delayed for some time after
SET_DEFAULT, since the session manager has to work on it.
MOVE_* commands need to know what the client thinks is the current
default sink, so that they can decide between "move to default" and
"move to specific device".
To avoid race condition here, stash the default value set by the client
and use it in the MOVE_* commands, until the metadata update arrives.
