Move the param enumeration code out of the main enum function.
Emit node events after completion of the set_param functions to ensure
we only emit things once.
Get the clock pointer using the io_changed stream event.
and update the clock before triggering the process
The clock needs to be updated in the data loop thread
and before triggering the process so move the calls to
`pw_stream_trigger_process` from gstreamer thread context
into the data loop thread context by invoking a callback
and update the clock inside the data loop callback
before the trigger
Sometimes you want to use the convolver as a delay without adding
latency so add a latency option to tweak the automatic latency
reporting. Use this in the upmix rear delay filters.
Collect the latency of the graph in filter-chain. We do this by first
inspecting the LATENCY ports on the plugins and us the notify value as
the latency on the node.
We then walk the graph from source to sink and for each node take the
max latency of all linked upstream peer nodes. We end up with the max
latency of the graph and emit this in the graph properties.
We then listen for the graph latency property and use that to update the
process_latency of the filter-chain, which will then update the latency
on the filter-chain ports.
Fixes#4678
Some ports can have latency information about the plugin, mark those
ports with the LATENCY HINT.
Also decouple the LADSPA hint flags from the SPA ones.
This allows to use the library in projects that use `-Wswitch-default`
without any
#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wswitch-default"
#pragma GCC diagnostic pop
This is useful as as the header is being pulled in via
pipewire/wireplumber headers into projects that might have this warning
enabled and would otherwise fail to build with -Werror.

3-way incoming calls are created in waiting state. When those calls are
hang-up before being active, the +CIEV: (callsetup = 0) should also be
managed for waiting calls.
One of the ideas behind retrying the sending of a failed packet with the
poll callback was to make sure that we do not end up with missing seqnums
by missing received credit due to some jitter.
However, the rate matching behaviour for ASHA is not clear and we do not
seem to face problems in local testing by just dropping the packet.
The two sides of a ASHA pair rarely if ever start together and the
sequence number was always a bit off due to the stateful nature of
reset_buffer and ASHA needing the sequence number to be matched to
the other side.
Simplify this by setting the sequence number for ASHA just before
flushing.
Rework the function a little so that it can take a list of formats and
only add the supported formats from that list and only once. It can
optionally select only the DSP formats.
Make a new PeerFormats param that can be set on ports to let it know
about the possible peer formats. This can be used by converters to calculate
an optimum conversion.
make the videoadpter query the follower formats, simplify them and then
set them as PeerFormats on the converter.
Implement peerformats in videoconvert. This makes EnumFormat on the port
depend on the negotiated format of the peer. It will suggest a Format
that most closely matches the current negotiated format with the available
PeerFormats. This then makes it possible to negotiate to the format that
would require the least amount of conversions.
Make the converter format a higher priority in all cases. The converter
has been negotiated first and is able to make a better suggestion for
the ideal format in all cases.
Make a function to create a filter. This is a pod that has all valid
defaults fixated and the invalid ones left unfixated.
Use this filter is a first attempt to negotiate a link format. The
effect is that a format will be chosen first that matches all the valid
defaults as much as possible instead of negotiating to the first thing
that matches.
Suppose we have a higher priority port with the format:
foo/bar
key: { default:1024, min:1, max:2048 }
And another port with two params:
foo/bar
key: 512
rate: 2/1
foo/bar
key: 1024
rate: 30/1
By first trying key: 1024 we negotiate to the more specific second property
with the higher rate.
