Some applications might expect the process function to run concurrently
with the callbacks. PipeWire tries to avoid this by using a lock for the
duration of the process callback. Make an option to disable this.
See #1576
When the node is suspended, don't take into account the lock-quantum
settings or else the graph would not want to change to the requested
quantum of the node.
Say we have a jack node with node.lock-quantum = true and
node.latency=256/48000. When it joins the graph and is suspended, the
lock-quantum is ignored and the node.latency is set on the graph.
After that, the lock-quantum ensures the graph quantum doesn't change
anymore until the node is suspended.
When we move a node from one driver to another, move the quantum and
rate if the target driver was idle so that we can mostly continue
uninterupted until a quantum/rate change is calculated.
When the driver is going to be idle or not running, avoid updating
the quantum.
This is mostly when a node is moved to another driver. Changing the
quantum of the old driver would have the clients briefly see the useless
quantum before being moved to the new driver.
We just check the initial size of the buffer and remember that, we
should not emit (or schedule) a bufsize change callback.
Emiting the callback should really only be done after the buffer size
changes after activate completed.
Fixes some jconvolver startup problems.
default-session-manager is only used in the pw-uninstalled.sh developer
script. c25cec230c added the ability to
use the system-installed wireplumber but other than that this option is
largely superfluous.
Drop it and pick whichever the first entry to session-manager is. For
the vast use-case of either MS or WP this will just work fine and for
the niche case of building both SMs one just needs to make sure the
order is as desired.
And in the case of no session manager, the config line to start the SM
is now commented out.
The sources are used by the documentation, so rather than duplicating
the checks for whether to build it or not, just define it as
always-present empty array and fill it when needed.
Otherwise we get a meson error if media-session is disabled but
documentation is enabled.
Upstream libcamera commit 32635054bc76e2ababd8ea2177fca1f88229541a
changed "planes" on `FrameMetadata` to be a function. Adapt
the plugin code accordingly.
Keep track of the last scheduled sync operation and wake up listeners
when it completes.
The waiters also compare against the last issued sync so that when multiple
syncs are pending from multiple threads, they will all wakeup instead of
just one.
Fixes some lockups with ardour6.
Right now, meson -Dsession-managers=wireplumber will fail the build
because the default session manager option is set to media-session - and
if that isn't being built we error out.
Use an 'auto' value instead, selecting the first session-manager in the
list as the default one.
We have -Dsession-managers and -Ddefault-session-manager, the latter is
currently only used for pw-uninstalled.sh. Let's adjust the error
message to use "default" so it's a bit easier to understand by this may
fail with -Dsession-managers=wireplumber.
When multiple links are created at the same time for the same port, we
get into a race where multiple links will try to set a format
asynchronously and eventually break the links. Avoid this by marking the
port as busy for as long as an async format or buffer is pending and
avoid starting new link negotiation when one of the ports is busy.
This problem was observed when ardour6 tries to link all device capture
ports to its single monitor port.
For the stream group, we break into the three components we write out
and print those.
For the IPv6 address printing inside [], we can make this a condition on
the printf statement.
In one we can duplicate the spa_asprintf call without real drawbacks.
The second one can be split up without losing details. Note that there
is another one in backend-native.c where splitting it up will make the
code harder to understand. The warning for that one remains.
Change codec factory names to api.codec.bluez5.*, so that they won't
conflict with old config file lib name rules for api.bluez5.*
Specify the fallback library name when loading the codecs, so that it
works without the rules in config files.
Check if we actually managed to add the param to the builder before we
try to deref it.
Use a safer deref that checks the sizes of the pod and builder.
Each dictionary needs to fully match but out of the dicts we have, only
one needs to match to apply. Reword that for clarity.
Also document regex vs normal string comparison vs the magic null
string.
This is a multi-step process involving 4 processes and two modules.
Let's add some graphs to make this slightly easier to comprehend for
those not familiar with how portals work.
