The workaround is typically needed with usb-cameras using jpeg streams.
Re-enabling the skip shouldn't affect what the commit was trying to do,
i.e. fix encoded streams like h264 etc.
Fixes: bcf0c0cf8 (v4l2: only skip buffer for raw formats)
If kernel socket queues for different streams get out of sync, it will
mess up time alignment of different streams. If that happens, flush to
resync.
If total latency becomes too large, flush queue.
Get accurate queue sizes from tx timestamping.
Use TX timestamping to figure out the accurate amount of unsent data,
including controller buffers. SIOCOUTQ does not report accurate data
size as it includes overheads.
Now that we have ASHA & BAP, this->device_set now refers to the device
set of the active profile. It cannot be used to produce
EnumProfile/EnumRoute.
Fix this by computing the device set for given profile(s) as needed.
Use `needs` to specify job dependencies explicitly instead of relying on
stages for ordering. This allows jobs from multiple stages to run concurrently
without having to wait for unrelated jobs in earlier stages.
See https://docs.gitlab.com/ci/yaml/#needs for more information.
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.
The params contain the send/recv streams from the point of view of the
manager (and not the driver as was assumed before). This means we need
to swap send/recv in the driver, not the manager.
This makes things interoperate with JACK/netjack2.
See #4666
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.
