Actually move the stream properties in stream.props object for the pipe
tunnel module.
Set pipe.filename on the node. Remap this to device.string in pulse.
Add some more default properties on the pipe nodes.
See #2973
Some older servers set the io area after starting the node and so the
node runs first without io areas, just return an error instead of
crashing.
Fixes#2964
Choose the closest match to reduce resampling loss. If match is not equal, resample.
Keep the backwards compatibility retaining `filename` property. When both set, `filenames` takes priority
Make a real debug context with a log function and move it to a new file.
This way we don't need to redefine a macro.
Make a new context for debugging to a log file. Make new functions to
debug to a log file.
Move the stringbuffer to string utils.
Integrate file/line/func and topics into the debug log.
We can remove some more things from the pipewire log_object function and
also add support for topics.
Add new spa_debugc_ funnctions that take a context. The user should also
redefine the spa_debugc macro to handle the context.
Use this to let some plugins log the pod and format to the log without
using the global logger.
Also use this to remove our custom pod logger function by reusing the
spa one with a custom context.
BlueZ may send multiple PACs in the capabilities delimited by zero LTV.
Handle this case by selecting the "best" one.
The configuration size may also for BAP generally be different from PAC
size.
Add a new macro to mark deprecated keys. The macro will emit a warning
about the symbol being deprecated.
PW_ENABLE_DEPRECATED will suppress the deprecation warning.
Add PW_REMOVE_DEPRECATED to completely remove the deprecated symbols.
Fixes#2952
Add SPA_SCALE32_UP that scales a uint32 without overflow.
Use this for scaling the threshold in ALSA.
Fix the scaling in audioconvert of the buffer size, the scaling was
wrong and it was also causing an overflow resulting in choppy sound in
some cases.
See #2680
Keep per stream audio info. We copy the global rate and format to
everything but allow for the channel positions to be overwritten
per stream. Invalid channel positions will revert to the default
again.
With a taget.object, this makes it possible to link the echo cancel
stream to specific pro audio sink ports.
Fixes#2939
Refactor get_rt_priority_range().
When we can't set the requested priority, use rlimit to clamp it
and try again. If this clamped value is bigger than RT_PRIO_MIN,
we can allow this.
The result is that the RTPRIO is set to the max of the user rlimit
RTPRIO, as long as it's more than 11. Previously it would fall back
to RTKit.
Add some more formats that can be used in pipewire streams so that
pulseaudio will see them as valid devices/streams.
It is possible that this will result in an invalid format on the client
when there is no pulseaudio format defined, but that is ok.
See !1499
Currently, doxygen is run by ninja in the top-level build directory,
therefore the "doc" folder is always created there. However, when
pipewire is built as a subproject, it should not touch the top-level
build directory because it can cause conflicts and because the
documentation won't be created where meson thinks it will be,
so the "doxygen" target will always be dirty and installation will fail.
If only one of rates is provided, propagate it. If both are provided and are inequal, warn.
This configuration appears to be broken for obvious reasons
A bug was introduced with the refactoring in da26563. In arm_init,
the buffer passed to spa_cpu_read_file is allocated and it is just
going to return that. So cpuinfo will actually point to buffer on
the stack, which need not be freed with a call to free.
The crash resulting with the incorrect free.

Split files into separate files.
Move type annotations to a matching -types.h files.
Move helpers to matching -utils.h files.
Add helpers to parse generic audio and video info.
Quoting https://docs.pipewire.org/page_dma_buf.html section "v4l2":
```
It's the the responsibility of the producer while the add_buffer event
to choose DMA-BUF as the used buffer type even though no modifier is
present, if it can guarantee, that the used buffer is mmapable.
```
As Gstreamer internally can mmap dmabufs just fine, support this case.
This enables dmabuf support with V4L2 and libcamera.
This was also tested against Gnome-Shell, which correctly handles this
case and only chooses DmaBuf if the negotiated format has a modifier,
i.e. if the Gstreamer peer supports the format with
`GST_CAPS_FEATURE_MEMORY_DMABUF`.
Fixes 602aa7d541
The drm format modifier value `0` is actually `DRM_FORMAT_MOD_LINEAR`,
a commonly used modifier. Unfortunately there appears to be no value
that can savely used as placeholder for "no value", as e.g.
`DRM_FORMAT_MOD_INVALID` is often used to indicate an implicit modifier.
Thus add a new flag that clearly indicates whether the modifier
value is set or not, add it to `spa_video_info_raw` and the util
functions.
Closes https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/2943
According to https://docs.pipewire.org/page_dma_buf.html, i.e. announce
each format once with, once without `SPA_FORMAT_VIDEO_modifier`
property.
Note: currently libcamera always uses `DRM_FORMAT_MOD_LINEAR` (`== 0`),
so `pix.modifier()` returning `0` does not mean that no modifier is
supported.
This is needed for clients using the new DMABuf negotiation pattern,
such as gstpipewiresrc after 602aa7d5.
