The module detects remote snapcast servers and creates a new sink
with protocol-simple for each server.
It sets up a new stream on the server for the sink with JSON-RPC.
If a node was unprepared and we're moving it to another driver, don't
try to unprepare and prepare it to the new driver because then we end up
with a prepare node that should not be scheduled.
Fixes#4017
Handle ipv6 addresses.
Support 0 port, which uses a free port to listen on.
Place the list of addresses we listen on as a property of the module so
that dynamically allocated ports can be retrieved.
Add macro SPA_CMP to do 3-way comparisons safely, and use it to avoid
signed integer overflows.
Fix also float/double comparisons (previously 0.1 == 0.8 since cast to
return type int).
Fix Id/Bool comparisons so they can return negative value.
Kernel-provided MTU does not work for USB controllers and the correct
packet size to send can be known currently only from RX. So we are
waiting for RX to get it.
The known problem is USB-specific, we shouldn't need the workaround for
other transport types.
Don't wait for POLLIN for non-USB controllers on connect, but ready
things on POLLOUT as usual.
For non-USB controllers, pick some sensible packet sizes to use
initially, before we switch to same size as for RX.
Since `spa/utils/cleanup.h` is not a private header anymore, there is
no need for a separate `pipewire/cleanup.h` since the definitions of
the cleanup routines can now be moved into the respective headers.
This makes it possible to discover a local RAOP, pulse or RTP services
and connect to them.
IPv6 addresses need the interface appended to local addresses to
make the connection work.
Add capture.props and playback.props to configure the created streams
with arbitrary properties.
Improve format parsing, make it possible to have different formats peer
stream.
Improve some of the property handling.
This can now also be used to upload a stream to a snapcast server, add
an example of this to the docs.
The default kernel pool size on the input is 200 cells. A cell is
about 28 bytes long so the maximum message that can be received in one
go is about 5600 bytes. This causes problems when using amidi to upload
larger sysex messages because they simply can't be received by the
sequencer.
It if however possible to increase this limit with the set_client_pool()
function. Increase the pool size to at least the quantum_limit * 2.
This ensures we can receive and send at least 2 quantums of raw data,
which should be a fairly long sysex message.
Make a min and max value for the pool size. There is an upper limit of
2000 in the kernel but make this configurable and clamp the final
pool size to the min/max.
Make the MAX_EVENT_SIZE 256, because this is how the sequencer seems to
splits the input data as well and it results in less wasted space in the
output buffer.
See #4005
The larger events need to be copied into the target buffer at the same
offset as the source buffer or else we overwrite the header and make
a corrupt buffer.
snd_midi_event_encode() will reset the encoder when it returns an
encoded event. It is possible that the function returns with an encoded
event when the internal buffer is full, in that case we need to push the
event and continue encoding without reseting the encoder.
0 is not a snd_midi_event_encode() error, so don't handle it like
one.
The messages, mostly sysex, can be split over multiple control message.
This happens when we read large messages from the sequencer, the
snd_seq_event_input function returns split messages that we transfer to
control messages directly.
When we send those messages out, however, the encoder wants the complete
message before it will return a valid event that we can send out. Keep
on calling the encoder with the control events until we get a complete
message that we can send out.
Fixes#4005
Add a count to each invoke item that is updated with an increasing
loop atomic counter. Flush items from the queues based on their count
so that items are flushed in the order they were added even if they
were added to different queues.
Instead of doing (cycle+1) & 1 for output ports, simply swap the io
areas depending on the port direction (0 = input, 1 = output) and
just to cycle&1 for all ports.
