When we duplicate the filter, also duplicate the control values instead
of reusing the same value for all copies. We then duplicate the value
ourselves when setting a control. This makes it possible to later use
this for volume control.
This will call the process function as soon as a new buffer is dequeued.
This can be used to keep the buffer at a certain fill level instead of
the minimal fill level without the flag.
Fixes#3480
Piggy back on the Latency param change to emit a stream changed event
because we now might have a link between the stream and a device.
We should really watch for new links and emit change events for the
streams that it links to.
Fixes#3522
This makes the clock.force-quantum setting and node.force-quantum
suspend all drivers and resume them in the new quantum.
This is essential in order to change the quantum on an IRQ based
driver because it will otherwise refuse to change the graph quantum.
Don't just forward the tag and latency events to the follower but let
the audioconvert aggregate and emit the updated tag/latency event
that is then configured on the follower.
When using the DSP mode of the audioconvert, this results in an
accumulated latency/tag from all the DSP ports instead of just
the last DSP port param update.
Put properties with media. prefix in tags in pw-cat.
Always first clear the params before we start enumerating new ones.
Otherwise we only clear them when we see the first result and there
might not be a result.
`wpctl status` shows the description of device nodes. Therefore, the
videotestsrc and audiotestsrc are listed as "(null)" if the example
configuration of the sources is used.
Set the description in the example for how to configure the audiotestsrc
and the videotestsrc.
Let the source write into a ringbuffer when there is data available.
We then read from the ringbuffer when scheduled and use a dll to keep
the delay constant. We can later make this a driver and use the rate
correction to tweak the timeouts instead of resampling.
See #3478
Round down the size and avail to the frame size to make sure we always
send aligned frames.
When we don't have the required size, set the buffer to 0 but still send
whatever we have in the ringbuffer or else it stays there until some
unknown time when it gets flushed out again with new data.
