We have various modules that set the priority higher than the dummy and
freewheel driver (ffado, netjack,...). This makes it impossible to use
the freewheel driver on them.
Use a memstream to collect the arguments so that it can dynamically
allocate as much memory as necessary.
Use a dynamic pod builder to construct the pods so that they can be of
arbitrary size.
Fixes#4166
Only set use the graph rate and duration when the ffado.sample-rate
and ffado.period-size properties are set to 0. Othersize use the
configure values.
Without this patch, it would just ignore the settings and always use the
graph rate.
Change the GenericFd data type to SyncObj. It's probably better to
explicitly state the data type than to make something generic. Otherwise
we would need to transfer the specific fd type somewhere else and there
is no room for that in the buffer and the the metadata is not a good idea
either because it can be modified and corrupted at runtime.
Add the SyncTimeline metadata. This contains 2 points on two timelines
(SyncObj datas in the buffer). The buffer can be accessed when the
acquire_point is signaled on the timeline and when the buffer
can be released, the release_point on the timeline should be signaled.
Add a SPA_PARAM_BUFFERS_metaType in the Buffers object. This contains a
bitmask of the mandatory metadata items that should be included on a
buffer when using this Buffers param.
Make the buffer allocation logic skip over the Buffers params that
require unavailable metadata.
This can be used to, for example, enforce specific metadata to describe
extra buffer memory (such as the meaning of generic file descriptors).
One such use is the explicit sync, where an extra buffer data is needed
for the sync fd along with metadata that contains the sync_point.
Parse the metas right after we fixate the params and collec them in the
metas array. We don't have to loop twice and then we can simply pass the
prepared metas to alloc_buffers.
In case there are multiple Buffers params, take the first valid one and
ignore invalid ones.
In order to show metadata changes when monitoring, a sync must be
triggered just like it is done for other objects, to make sure that
`dump_objects()` is called some time later and the changed metadata
objects are shown.
Otherwise metadata changes would never be displayed unless there
was a change to a different type of object, whose event handlers
do trigger a sync.
Fixes#4053
When for some reason we don't manage to transfer data from the source
or to the sink (timeout, scheduling problems..), try to do it when we
get a timeout to avoid xruns.
`registry_event_global()` creates an `object` object for every object,
not just those matching `data::pattern`. However, previously
`registry_event_global_remove()` only destroyed those objects
that matched the given pattern. Fix that by destroying
every object.
Fixes#4001
Fixes 47e1f38f03 ("pw-dump: also dump object removal")
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.
(cherry picked from commit e2e8cf7944)
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()`.
Fixes: cacdcc1b62 ("pw-mon: add filter param to hide props and/or params")
Fixes#3997
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.
See #3994
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")
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.
