Always reevaluate the rate matching even when we did not change the
follower state.
It is possible that we were a follower from some node with the same
clock and now become a follower of a node with a different clock. The
follower state doesn't change but we need to activate the rate matching
logic in that case.
Fixes rate matching in pro audio (playback) when capture and playback
are moved to another driver.
Variables enclosed with @ are replaced with the value of the variable.
The sink.name should remain @DEFAULT_SINK@.
Escape the enclosing @ to prevent substitution of DEFAULT_SINK with an
empty string while generating pipewire.conf.
We first need to do the setup, which we start when setting the Format
param.
This causes the module to unload when starting pavucontrol because it
tries to start the record in the wrong state.
See #3778
After we set the format, probe if we can do EXPBUF and enable/disable
the ALLOC_BUFFERS flag on the port.
This should gracefully handle the case where EXPBUF is not available.
Fixes#3821
When we try to alloc buffers but EXPBUF is not supported, make sure to
clear the alloc_buffers flag so that the caller can try again with
allocated buffers instead.
See #3821
If the manager gave us a different channel count than we had by
default or configured, assume everything is AUX channels.
Also handle the case where the manager is sending more than our
MAX_CHANNELS channels.
Move some of the tracking code for the DLL to where it is used.
Add resync.ms (default 10) option at which we give up rate adjusting
and instead do a hard resync. This results in a jump in the position
of the graph clock.
When we get a node info about our own state, we can use the active state
of the node to decide if we are running or not.
Otherwise, we will try to hide ports from JACK clients that suspend
(while still active).
See #3794
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.
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.
When freewheeling we will immediately schedule a new graph cycle when we
get a process call because the graph completed.
When the process call is not done, because of some xrun or
because some node was removed that causes the graph to fail completion,
The next cycle will happen after a timeout.
This timeout was calculated as the ideal wakeup time (after a quantum of
time) and would accumulate for each timeout. The result is that the
timeout ended up far in the future and would stall the freewheel driver
for a long time.
Fix this by always setting the next timeout to wakeup time + freewheel.timeout
seconds. Also add a config property for the timeout (10 seconds, like
jack2 by default).
Primark True Wireless earbud doesn't support sbc-xq. Having it
enabled causes bluez to enter into a loop enabling/disabling
the device dozens of times per minute, making it unusable.
GStreamer uses a time stamp for the decoding time, but PipeWire uses an
offset to the presentation time. Thus, the pipewiresink must not use the
DTS as dts_offset, but has to calculate the offset.
If the buffer's DTS is invalid, assume that dts is pts.
get_device_info() requires us to call update_object_info() in the added
and updated events.
Fixes a bug where the properties were invalid in the avahi txt record.
When the session manager sends an error to the client, it typically
also destroys the node after the error, which causes the stream to go
to STATE_UNCONNECTED via proxy_removed(). In that case, make sure
we exit the loop early, otherwise it will take 30 seconds to unblock
gst_element_set_state()
This is a revised version of the fix that was commited via !1763
and then reverted, as it was problematic. Now the code ensures
that it breaks out only if the state was previously CONNECTING
or higher.
The monitor sources also list the port of the sink and so the active
port needs to be collected as well so it doesn't fall back to the first
port (which might not be available).
Keep a list of ports for the node. When the node goes away, clear the
port links to the node. Handle the case where the port no longer has a
node.
This avoids a crash when, for example, the node permission is removed
and the port points to the now freed node_data.
Fixes#3708
