We can increase the MAX_LATENCY again if we increase the amount of
buffers when we are using a small buffer.
Normally we ask for 4 * quantum-limit as the buffer. This should be good
to use 1 buffer and quantum-limit as the quantum with enough headroom
to not run out of buffers.
If we are however using less buffer-frames we need to be careful and
allocate an extra buffer. Imagine using a buffer of 4096 frames, we can
support a quantum of up to 2048 frames if we use 2 buffers.
See #3744
Half of the buffersize is not enough to support as a max-quantum, we
need to divide by (4 * frame_scale) to allow some headroom and account
for the DSD scaling. We do the same calculation to suggest a buffer size
using the quantum-limit.
See #3744
When the filter has no format property, just enumerate all possible
framerates. Handle error case where the filter has the wrong type.
Makes gst-launch gstpipewiresrc ! video/x-raw ! fakesink work.
See #1793
Actually count the number of frame fractions we add. If we added 0, we
don't have any supported framerate that intersects with the filter and we
try the next frame size.
See #1793
When we are notifying the application of changed params, don't emit any
changes applied to the params from within the callback with
pw_stream_update_params(). This will be done after we complete the
callback.
This also avoids reseting the change counter so that we don't
accidentally think we updated the formats param when we simply changed
some other params.
Only listen for packets from source.ip in the unicast (v4) case by
calling connect(). If packets from any source address is wanted, set
source.ip = "0.0.0.0".
Not waiting for HFP when no HFP backend should be checked via
adapter_connectable_profiles in spa_bt_device_check_profiles where the
relevant logic is.
Cleanup by moving the checks there.
Now that both the expected input and output of the resampler is placed
in the rate_match, rename the 'requested' field in pw_time to 'size'
and update the docs.
See #3750
Now that the resampler input size is set in the io_rate field when we
start we can add it to the pw_time struct as well.
This way we can know the required resampler input without having
to dequeue a buffer. This can be handy when the stream is a driver
and needs to know how much data to accumulate before starting the graph.
See #3750
When starting the converter, calculate the initial size needed by
the resampler to fill one quantum.
This makes it possible to get the requested amount of samples before
the first process call is made.
Unknown transports visible in DBus usually belong to a different
sound server instance that is talking to BlueZ.
Explain this in the warning message that we log, so that people can more
easily understand why things are not working.
SNAP containers have two main "audio" security rules:
* audio-playback: the applications inside the container can
send audio samples into a sink
* audio-record: the applications inside the container can
get audio samples from a source
Also, old SNAP containers had the "pulseaudio" rule, which just
exposed the pulseaudio socket directly, without limits. This
is similar to the current Flatpak audio permissions.
In the pulseaudio days, a specific pulseaudio module was used
that checked the permissions given to the application and
allowed or forbade access to the pulseaudio operations.
With the change to pipewire, this functionality must be
implemented in pipewire-pulse to guarantee the sandbox
security.
This patch adds support for sandboxing permissions in the
pulseaudio module, and implements support for the SNAP audio
security model, thus forbiding a SNAP application to record
audio unless it has permissions to do so.
The current code for pipewire-pulseaudio checks the permissions
of the snap and adds three properties to each new client:
* pipewire.snap.id: contains the Snap ID of the client.
* pipewire.snap.audio.playback: its value is 'true' if the client
has permission to play audio, or 'false' if not.
* pipewire.snap.audio.record: its value is 'true' if the client
has permission to record audio, or 'false' if not.
These properties must be processed by wireplumber to add or
remove access permissions to the corresponding nodes. That
code is available in a separate patch: https://gitlab.freedesktop.org/pipewire/wireplumber/-/merge_requests/567
Handle extend == 0 and don't expand the array but return -ENOSPC.
This makes it possible to handle static arrays, make a function to
make this easier. Remove pw_array_add_fixed() now that we support
this with extend==0 and because it was not used.
Round up the required space to next extend so that the total allocated
size if always a multiple of the extend.
Make pw_array_add_ptr() check for allocation errors instead of crashing.
Try to use `media.name` as the display name for a node
when none of the other keys are found in its properties.
For example, `pw_stream_new_simple()` only sets `media.name`
on the created node object by default.
