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.
Also clamp the amount of input samples we push when flushing. do several
rounds of zero pushing until we have flushed enough.
Handle the cases where no input is needed or no output is generated.
Fixes crashes when downsampling from 96000 to 1000 Hz or so.
The order of attribute changes is random, so it's possible that controlCX is
accessible before the other devices, which marks the device as available but it
actually fails to open. Only consider the device accessible if both control and
PCM devices can be accessed.
This requires reacting to ATTRIB changes of pcm devices as well now.
Fixes#2534
We need to check the last offset against the size of the buffer, not the
remaining size in the buffer.
When the writing is split, this could cause the buffer to be reused
wrongly.
See #2536
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.
