Keep per graph latency. Sum all the graph latencies together and keep
this around as the process-latency.
Refactor the port latency setter. Make a function to recalculate the
latency of all other ports. Take into account the graph latencies.
Update the port latencies when the total graph latency changes.
First do the essential properties to set up the node, then set up the
node and then parse the params. The params might do some setup that
relies on a completely configured node, such as emit events.
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.
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.
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.
Set different icons for A2DP & HFP output routes, so that they look
different (in Gnome).
Don't call the non-HFP output route as "headset" or "handsfree" in this
case, to be less ambiguous about microphone availability.
Also set device.icon-name for the device too.
