e4323df347 Resolves issue #244 - updates the P25 IMBE audio module to correctly
detect encrypted audio state so that encrypted audio is not (incorrectly)
decoded and played back to the user.

Processes HDU and LDU2 messages to identify encrypted call state.  Once
established, all subsequent LDU1/2 messages are decoded only if the call
is unencrypted.  If an LDU1 message is received out-of-sequence, meaning
that the initial HDU message was missed, then the LDU1 is cached until
we receive an LDU2 message and correctly determine the call encryption
state.

6bfe98dae6 #78 patch group alias and call event management. Adds new PatchGroupAlias which is a temporary alias group that is added to the alias list by the decoder state. The P25 decoder state maintains a mapping of patch group identifier to patched talkgroups and creates the patch group alias. This allows audio recording and audio streaming of patched talkgroups, according to the aliases corresponding to the group of patched aliases contained in the patch group alias.
Event logging is now pared down to only logging events when the internal patch group mapping is updated.

a56935f92c Closes #74 - adds support for vendor-specific (Motorola) TSBK patch group management. Processes patch group channel grants and updates and allocates voice channel processing. Logs call events for patch group add (register) and patch group delete (deregister). Also adds call event logging when there is a planned control channel shutdown--logged only once. 2016-07-31 07:52:01 -04:00

12ff5513b7 Adds preliminary support for legacy P25 CAI VSELP voice frames. VSELP 1
and 2 messages simply capture the message at this point -- don't yet
know the format for the voice frames and embedded signalling.

4025f88951 P25 and Airspy work in progress
Updated p25 decoder state to better track calls and call detects from
a trunked channel

Fixed issue with false detects on LDU2 encrypted call messages

Fixed Airspy channel allocation ... will allocate channels across the
entire bandwidth, minus 50 kHz on either end, and will not adjust the
center frequency if it's not needed.

Fixed traffic channel teardown -- traffic channels are immediately 
removed now, without a fade delay.

AudioMetadata - updated flag is now reset upon copying the metadata

f4d8ea281d Initial commit of redesigned internal processing and audio management.
Note: Several of the decoders are currently non-functioning in this
commit.  If you want the latest functioning codebase, please checkout
the commit prior to this one.  All decoders will eventually be updated
with this new architecture.

Currently broken:
- Logging and recording
- Aux decoders (Fleetsync/MDC/LoJack/Tait)
- LTR/Passport decoders

Changes in this commit:
- Module architecture for decoders and components with central
provisioning by the DecoderFactory
- Transition from Complex sample stream processing to float buffer
processing for improved memory management
- Redesigned filter structures - to support buffers and streams
- Resolved several memory leak issues
- Universal sharing of the thread pool manager
- Added centralized audio management with call/user prioritization and
new gui with mute/volume controls
- Embedded audio metadata for eventual streaming support
- Redesigned ProcessingChain to support independent re-use
- Added new TrafficChannelManager to handle traffic channel allocations
- Traffic Channel pool size and Call timeout available in P25 and
MPT1327 configs
- Redesigned channel and decoder gui components
