Use the new requested buffer field to only queue the amount of samples
required by the resampler for the current quantum. This avoid spikes
when the maxsize block of samples is processed.
Fixes#2353
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.
The posibility to drop single modifier was added in this development
circle (after 0.3.39 release). To have clients work with older versions
of PipeWire dropping all modifiers can be an option.
Let video-src unconditionally call _trigger_process() when it is
ready. This will either start the graph when it is the driver or emit
a RequestProcess event to the driver.
Let video-play-pull intercept the RequestProcess command and use it
to do a trigger_process(). Otherwise use a timer to pull in the next
frame.
This commit uses the video-src-alloc and video-play-reneg templates to create
examples for manual fixation at the format negotiation phase. These
clients simulate modifier negotiation done by clients handling DmaBufs.
Note: Neither client is capable of proper DmaBuf handling!
video-play-fixate can be used to test if a producer is capable to
fallback to shm buffer transport, while video-src-fixate can only be
used with the former example!
The previous code had alsa optional if pipewire-alsa was on
auto/disabled bug failed later with missing alsa if media-session was in
the session manager array. Which it is by default.
Fixes#1632
If the device doesn't have an active Route, also check the EnumRoute to
see if there is something available. If nothing is available, also avoid
selecting this node.
Fixes#1624
For default nodes, that are explicitly configured, skip the route check.
This makes it possible for the user to select a non-available node
as the default still.
Fixes#1624
It's not really the responsibility of the session manager to load the
bluez5 device quirks, and it's easier for eg. Wireplumber if it doesn't
need to do it.
Move loading bluez-hardware.conf to be the responsibility of the bluez5
spa plugin, similarly as the alsa plugin deals with the ACP database.
Put the configuration to share/spa-0.2/bluez5, mirroring the plugin
directory structure in lib/spa-0.2/bluez5.
When none of the nodes have a valid passthrough format, don't check if
passthrough is possible.
Without the check, it is possible that a node has a common format with
the peer that is not a passthrough format, like a raw audio format.
Fixes#1587
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.
Instruct the policy to not configure audio adapter nodes in DSP mode. Instead,
Device nodes will always be configured in passthrough mode, and client nodes
will be configured in convert or passthrough mode depending on whether the
client format matches the device format or not.
The current _info_update() methods will always reset the change_mask in
the new info structure.
This causes problems if multiple updates are applied to the info before
the rescan in the session manager of pulse-server is excuted. The first
update is cleared and this causes the session manager to sometimes miss
the state changes of nodes and fail to suspend them.
Add a new method to merge with optional reset of the various
introspection info structures. We can use this instead and simply
accumulate all changes until the rescan code has processed all changes.
Make sure we always suspend before reconfiguring a device.
Put the node and the device in passthrough mode when requested. Move
back to DSP mode after the node is unlinked.
Parse the exclusive flag of a stream once when the node info changes.
Use a new variable 'passthrough' to remember the current state of
a node and the peer.
Parse non-raw formats as well.
Check if two nodes can passthrough by intersecting the EnumFormat
params. If it is possible, configure the node for passthrough.
Don't try to reconnect nodes in passthrough.
Fail if we can't find a node compatible with passthrough.
See #629
If a program using pipewire-alsa calls snd_pcm_close() immediately after
snd_pcm_prepare() without reading or writing any data the client node
may be removed before the session manager can link it, which would
result in the following log warnings:
can't link 35:40 -> 43:48: link-factory: unknown input port 48
error id:25 seq:11467 res:-22 (Invalid argument): link-factory: unknown input port 48
can't link 35:41 -> 43:46: link-factory: unknown input port 46
