Updated audio packet wave recorder to correctly dequeue audio packets
to ensure that the overflowable buffer queue accounting process was
working correctly.
Updated overflowable buffer queue's poll() method to correctly decrement
the queue size counter.
Resolved issue where the mutable metadata was being prematurely reset
and causing the end audio packet to be mis-identified. This resulted
in the recording manager not stopping the recording on command with the
timeout mechanism kicking in after a brief delay.
so that the modules are reset after they are shut down, in order to
prepare for processing chain reuse.
Previously, the modules were reset upon startup, but after any traffic
channel metadata had already been transferred to the channel state,
causing the metadata to be lost and allowing initial audio packets to
stream without any metadata and related streaming/monitoring rules.
only update the center frequency when needed and to place the set of
decoding channels adjacent to the right side of the tuner's center
frequency when the complete set of channels fit into the usable half
bandwidth of the tuner.
Adds 500 ms delay to initial registering for samples from all tuners to
feed the spectral display/waterfall. The existing approach of immediately
registering for samples was causing the airspy tuner to lockup
aperiodically. Investigation via debugger didn't show any application
thread locks ... usb master processor was continuing to service libusb
timeouts. Unable to debug internal airspy processes. Adding the delay
to startup seems to be a usable solution.
Reverts PLL gain values to version 0.3.4beta2 values to restore P25
decoder performance.
This change in conjuction with recent channel sample rate change should
restore P25 channel decoding to comparable levels from 0.3.4b2.
Updates decoder types to specify channel sample rate and pass/stop
frequencies for requested channels. Updates tuner channel source
managers to accept a channel specification for channels that are
allocated.
channel manager so that channel source requests can have a start
timestamp specified and the channel can be preloaded with samples from
the delay buffer. If no timestamp is specified, current time is assumed.
This feature requires corresponding updates to any decoder that wishes
to implement the timestamped sample preloading functionality.
