Use `meson.project_{build,source}_root()` instead of
`meson.{build,source}_root()` because those functions
do not work as expected when used inside a subproject,
and they have been deprecated in meson 0.56.0.
The paths are calculated relative to the project root,
so use the appropriate functions to retrieve it
instead of using the current build/source directory.
Commit d06a2e2140
added support for finding libcamera under two different
names. However, due to breaking changes in libcamera[1],
the current codebase only supports the latest version,
thus drop support for the old name.

Previously, when a sample is "committed" from an upload stream,
its reference count is set to 1. This is problematic if,
when the sample is committed for a second time, there are
streams playing the sample as the reference count will go out
of sync.
The problem can be easily triggered, especially with longer samples:
pactl upload-sample a-long-sample.ogg
pactl play-sample a-long-sample
pactl play-sample a-long-sample
pactl upload-sample a-long-sample.ogg # while playing
When the first stream finishes playing, it will free the sample,
which can cause problems e.g. for the second stream playing the
sample at that very moment.
Fix that by decoupling the buffer from the sample and making
the buffer reference counted. And remove the reference counting
from the samples as it is no longer needed.
Futhermore, previously, the reference counts were ignored
when the removal of a sample was requested. That is fixed
as well.
The previous issue can be triggered easily as well:
pactl upload-sample a-long-sample.ogg
pactl play-sample a-long-sample
pactl remove-sample a-long-sample # while playing
Fixes#1953
Create a new event for modules ('destroy') which is emitted from
`module_free()`. It is used by the module loading logic, to handle
when a module is destroyed without properly loading first.
Store the modules whose load has been initiated by a particular
client in the `pending_modules` list of the client. When the
client disconnects, "detach" the client from the pending module
objects. This way the reference count need not be increased
for asynchronous module loads.
Furthermore, if the module can load synchronously, do not create
the pending module object at all.
Only call `spa_list_remove()` in `stream_free()` if the
stream is pending. `spa_list_remove()` does not reinitialize
the list node, therefore calling `spa_list_remove()` again
after the stream has been removed from the pending list
will corrupt the pending list of the client.
When we can't fill a complete block, report the amount of data that we
used in missing/played instead of the complete missing part.
Fixes audio breaking up when looping in mpv.
Fixes#1132
After we get a reposition request, bring the state to the SYNC state
again so that clients can align with the new position.
Fixes a problem with reposition when using the jack transport.
Fixes#1907
If the supplied buffer has smaller (or equal) size than the
length of the string, then `strncpy()` will not place a null
terminator in the buffer.
Fix that by always setting the last byte of the buffer to zero.
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.
Always reevaluate the tlength or total buffered samples when the
quantum changes, even for the first sample because it is possible that
we completely miscalculated the length when we started, like when the
quantum is force high and the requested latency is low.
Also only increase the calculated tlength, for smaller sizes we don't
need to do anything, we can keep the latency as is it.
See #1930
When we are draining or underrunning, read whatever we have in the
ringbuffer instead of silence. This places the last samples before
the drain into the sink, padded with 0.
Fixes#1549
This reverts commit c14e89a578.
This makes it impossible for flatpak apps to remove links. Maybe:
- Flatpaks apps are not allowed to make lingering links
- Flatpak apps can only delete their own links.
- Some flatpaks apps needs to be tagged as manager in order to created
lingering links and destroy any link.
Fixes#1920
When we have a fix_* flag set, make an extra format description with the
wildcards. This makes it possible for the session manager to fall back
to something when selecting a target and format.
Also only advertize the valid pulseaudio formats for the wildcards.
Fixes#1912
