To make an rnnoise filtered source:
pactl load-module module-ladspa-source source_name=rnnoise_mic label=noise_suppressor_mono plugin=/usr/lib64/ladspa/ladspa/librnnoise_ladspa.so
To make an equalizer sink:
pactl load-module module-ladspa-sink sink_name=eq_out label=mbeq plugin=/usr/lib64/ladspa/mbeq_1197.so
When inputs/outputs are specified, find the node:port and link them.
Fall back to the first/last node for input/output if no node is given.
Fall back to all input/output ports when no ports are given.
If the profiler manages to fill the complete buffer, we would have 8MB
of data that we need to allocate on the stack. Don't do that and instead
use a preallocated buffer large enough to copy things into.
SPA_MEMBER is misleading, all we're doing here is pointer+offset and a
type-casting the result. Rename to SPA_PTROFF which is more expressive (and
has the same number of characters so we don't need to re-indent).
To set the io on the mixer ports, we need to use the same id that
was used to add the port, not the id we use to identify the mixer
structure.
Fixes#759
Only implement the null echo cancel implementation for now.
And skeleton webrtc echo cancel implementation
It uses 4 streams arranged as:
input ---+---> source
^
|
sink ---+---> output
The output of the source is the filtered input of the input stream
(linked a master source) based on the data going from sink to
the output (linked to a master sink).
All streams are arranged in the same group so that the echo canceler
does not have to deal with clock drift. For echo cancelers that can
handle clock drift we might want place the source and sink chains
in different groups.
Pass properties as global properties so that they are applied
to both streams. Make sure node.name is set on both streams so that
they look good in tools like carla.
Do not return an error immediately if connect() fails with EAGAIN. Check
if it completed successfully with getsockopt() when the socket becomes
writable instead.
This is the way to handle non-blocking connect() by the book but after
testing it seems that the case when connect() fails with EAGAIN is when
the listen backlog is full on the server side and in that case the
server socket is closed. So even though connect() completes successfully
according to getsockopt() the client socket is no longer usable
(on_remote_data() will get both SPA_IO_OUT and SPA_IO_HUP in mask on the
first call after connect() returned EAGAIN).
Make it possible to specify different channels and positions
per stream so that we can do remapping as well.
Make sure we only copy available input channels and set the remaining
channels empty.
