Parse the quantum_limit parameters and use this to scale the buffers so
that they can contain the maximum allowed samples instead of the
hardcoded 8192 value.
See #1931
We take half of the current quantum as the period size for batch
devices. Limit this to the default quantum to ensure we don't end up
with too much headroom.
The pulseaudio pa_ato* functions set errno and return -1, when the
number cannot be parsed.
Some parts of parsing the profile files (e.g. parse_eld_device) rely on
these functions returning errors when the input is not a number.
Make the alignment parameter optional when negotiating buffers.
Default to a 16 bytes alignment and adjust for the max cpu
alignment.
Remove the useless align buffer parameter in plugins, we always
set it to 16 anyway.
Currently, `release_card()` uses `find_card()` to find the card
by the index stored in the state object. However, `find_card()`
increments the reference count of the object, therefore
`release_card()` will drop the reference that it has just
created by calling `find_card()` and not the "calling scope's"
reference. This prevents the card objects from being
freed when the SPA handle is cleared.
Fix it by having `release_card()` take a pointer to the card
and not its index.
The `card` structure uses `uint32_t` for its index member,
on the other hand, the `state` structure uses `int`. No code
depends on it being `int`, therefore change it to `uint32_t`
for consistency.
EAC3 needs to be opened in 4x the rate of the EAC3 stream, which can be
32, 44.1 or 48 KHz. Some clients already multiply but others don't.
Check here what is the case and fix it up.
Fixes#1902
The id is useless when dealing with props params, we need to use the
name of the property as the key. Also the id can clash with other ids
of other plugins.
Add PropInfo for all the params that we can configure at construct
time and also add them as PROP_params.
This way you can configure the headroom at runtime with this:
pw-cli s <id> Props '{ params = [ "api.alsa.headroom" 1024 ] }'
Expose the card object and always obtain one per pcm.
Keep the configured format in the card object.
Add a api.alsa.multi-rate property. When multi_rate is disabled,
only allow the last configured card rate on all PCMs.
This works around drivers that can't handle multiple samplerates
on their PCMs.
With this patch it should be mostly safe to configure multiple
sample rates in pipewire.conf
See #1547
The pulseaudio channel map can only hold 32 AUX channels and we reuse
them when we need more. When we find a duplicate channel, map it to the
next AUX channels.
