Log device name and stream direction
Don't log xrun errors in alsa, we signal the xrun signal, which should
take care of logging if any.
Log quantum in xrun.
ratelimit xrun messages.
The announce messages are not put in a queue so we don't need
to allocate one (and a timer). Without the timer, we avoid wakeups
and consume less power.
See #225
We only set the OUT flag when we put the buffer on an io area and
might need to recycle later.
Before placing the output buffer into the io area, recycle any
buffer that might be left in there.
Only emit the ready callback when we have some data queued.
If we get an error after receovering, ignore it and assume we filled
the buffer completely. We need to do this or otherwise we stop the
timer and audio stops.
JACK can handle 2 buffers at most, make the default buffer allocator
allocate 2 buffers when no params are given.
Prefer 2 buffers, it allows some form of async fill/consume
We can produce data whenever the io area status != HAVE_DATA. We
don't need to look for NEED_DATA.
Also recycling buffer happens whenever the status != HAVE_DATA.
The card name (id) can be configured with udev rules to remain
constant based on where the device is plugged in even when there
mulitple of the same devices.
This allows the upstream node to put buffers back to its pool in case
they were left around in the ready list locally when the alsa-pcm-sink
was last paused.
Fixes#203
This is more in line with wayland and it allows us to create new
interfaces in modules without having to add anything to the type
enum. It also removes some lookups to map type_id to readable
name in debug.
FreeBSD doesn't provide timerfd and eventfd functions. These are implemented in
3rd party library called epoll-shim. Link targets requiring these functions to
this library.
Add some padding, tweak some padding
Remove count in the clock, it's useless
For video frames we will want to use metadata to place
this on individual buffers.
Add a clock name to the clock, remove the old api/clock_id. This makes
it easier to add descriptive names
Place the alsa card number in the clock name.
Check the clock name of the master clock and if it matches our own
clock, disable rate matching.
Add flags to the rate match io area
Add flag to activate/deactivate rate match
Set active flag in rate match when slaved
Update rate before starting resample
