Check for NULL when importing a buffer and log a message instead of
trying to deref the NULL pointer and crash.
Add some more logging to mem when importing a bad fd.
See #3998
gst_pad_get_current_caps may return NULL and passing that into
gst_caps_is_equal may result in fatal critical log due to the
"g_return_val_if_fail (GST_IS_CAPS (caps1)" check. Fix by checking for
NULL to avoid this.
(cherry picked from commit 95127d8a18)
Some clients like many camera apps, including Cheese or Snapshot,
trigger a lot of unnessecary renegotiations. While arguably that should
be solved on a Gstreamer level, we can help out by checking if the
preferred new caps are the same that are already in use and skip the
renegotiation in this case.
This allows several apps to e.g. take pictures without a slow and heavy
stream restart.

Using `g_autoptr` and related modern helpers more often makes
the code smaller, easier to follow and maintain.
No behavior changes intended.
(cherry picked from commit 594e3fa09f)
All pw_core event handlers (`on_core_*()`) currently receive a pointer
to `struct data`, not `struct proxy_data`; as can be seen from the
`pw_core_add_listener()` call in `main()`.

Both the GPtrArray and its contents are leaked in case of success.
`pw_stream_connect()` copies the params as needed, so use `g_autoptr()`
to free the array and with it, its contents.
The threadloop might fail to create because of missing plugins, so
handle that.
The context might fail to create because of some fatal config error or
missing plugin, handle that too instead of crashing.

Debug and trace log messages are often written based on the stderr
logging, where code location is always visible.
journalctl does not show the code location without extra tricks,
which makes user-submitted debug logs from journal more cryptic.
Make journal log more similar to stderr logs by prepending the code
location and log level in the log message when the log topic
level is >= DEBUG.
Move the bits that are used in the realtime thread away from the bits
from the main thread to avoid bitfield races. Move some fields in rt
structs to make it explicit that they are only to be modified from the
realtime threads.
When resample.disabled=true, which is now the default, Format has zero
rate, so latency buffers get zero size. The rate in this case is the
graph rate.
Fix by just using the delay in samples, as all streams must in any case
run at same rate for the combining to work.
Fixes: bff252ce60 ("combine-stream: actually make use of resample.disable")
The eventfd is read/written from/to the data thread and the main thread
concurrently with the update_active() function.
Use an atomic compare and swap to make this update atomic and avoid an
inconsistency between the active boolean and the eventfd. This could
result in the eventfd being unsignaled while the active flag was true
and the application receiving a timeout and XRun in its poll loop.
Fixes#3711
resample.disable was made to default to true, but copying it to stream
properties was forgotten so it didn't have any effect. Make sure to copy
it.
This will also prevent different input/output streams from negotiating
to different rates, which would result to broken audio since we are just
passing sample data through.
A quite big number of UVC cameras - due to firmware or kernel driver
issues - have bad timestamps of the first frame, confusing clients
like pipewiresrc.
Drop the first frame, as this seems to be the most reliable workaround
for the time being.

clear_port() clears all struct mix and removes the port, and can occur
before port io is set to NULL. In this case the port memmaps are not
freed, and are leaked until client pool closes.
Fix by freeing the old io memmap when setting io to NULL, also when the
port was already cleared, so that the memmap lifecycle is the same as
that of the IO.
false by default, when true, no warning will be logged when the
context.modules in the config is empty. This can be useful when the
application wants to load all the modules itself.
We don't actually do anything when the name, factory or path is NULL so
don't count this as an action.
Commenting out these keys is a usual way for commenting out complete
sections.
Call _activate() in the aec spa plugin before both capture and sink
streams are started and call _deactivate() after both capture and sink
streams are stopped, to make sure _run() is not called while the spa
plugin is inactive.
