Denny	ef172a04c6	Cleanup - removed synchronized blocks since the buffer processor thread is the only thread managing recorders.	2017-03-03 10:04:21 -05:00
Denny	a877afcceb	Updates buffer processing in recorder manager so that we're not blocking any of the decoding channel producer threads that are trying to push audio packets to the recorder manager. Adds an overflowable packet queue and services the queue once a second followed by an idle recorder check (and disposal).	2017-03-03 10:01:32 -05:00
Denny	f51ae0b5da	Resolves issue with periodic instances of audio recorders not being shutdown correctly. Adds recorder monitor as a fail-safe to automatically shutdown recorders that don't receive an end-call indication.	2017-03-03 05:56:32 -05:00
Denny	6e94d9ce51	#108 [WIP] Created new ThreadPool class with a static ScheduledThreadExecutor that is now shared by all components. Removed ThreadPoolManager from all classes. Consolidating into 1 pool seems to have reduced CPU usage by ~15-20%. Overall memory usage is also reduced.	2017-01-22 09:33:47 -05:00
Denny	a57183c4cc	#90 - updated metadata and attributes to carry channel system/site/name values to support audio recording name generation. Updated always unsquelched decoder state to reset the PRIMARY_TO address to the channel name since the decoder will never push a value to this attribute and it's needed to correctly display audio content.	2017-01-22 06:44:07 -05:00
Denny	bc8873de01	#90 [WIP] merged metadata management for channel state, decoder states and audio metadata into a new metadata class. The new metadata class is maintained for each decoding audio channel, or in the future, a decoding TDMA channel. Audio playback, recording and streaming all use the same metadata object for the channel. The list of channel processing gui panels have been deleted and channel processing status will now reside in a table where each table row is a metadata instance from the processing channel. The channel processing manager is responsible for adding/removing the channel's metadata instance to/from the metadata table. This allows the channel processing table to be the controller for the messages, events and channel spectrum views, keyed to the selected table row metadata. ... I still have to clean up the gui components and wire in the table selection listeners.	2017-01-17 19:24:54 -05:00
Denny	7865e813de	#66 resolves issue with baseband recorders and loggers not being removed from channel processing chains when processing stops. This is now handled in the channel processing manager where baseband recorders and message/event loggers are added at processing start and removed at processing stop.	2017-01-08 05:21:42 -05:00
Denny	0cf26da94e	#65 resolves issue where on audio recorder startup an IO exception is thrown. Traps the exception and shuts down the recorder.	2017-01-07 10:56:57 -05:00
Denny	3af4b953f4	Changes internal audio sample rate from 48 kHz down to 8 kHz. Updates the P25 audio module to output 8 kHz audio. Updates the audio recorder to record at 8 kHz rate. ... Note: required updated JMBE 0.3.3 library which supports 8 kHz audio output sample rate.	2016-08-19 21:09:39 -04:00
denny	f7f6c2fc3e	Merges changes from master branch to resolve issue with CPU and memory ... and constraints on scheduled thread pool saturation. Adds a new scheduled thread pool for each processing chain that the components in the chain can share, versus the single shared pool exposed by the threadpoolmanager class.	2016-02-15 15:47:14 -05:00
denny	4be63d4b95	Work in progress. ... -Started work on new channel editor channel viewer/controller -Removed a number of unused buffer package classes -Moved automatic frequency control to be a module and removed special handling -Added IUnfilteredRealBufferListener & Provider interfaces -Completely removed the ResourceManager class	2016-02-13 14:57:12 -05:00
denny	67b4aa3a0e	Adds error handler for new audio recorder starts. Currently chasing a ... bug where Linux runs out of FileDescriptors, even though we're explicitly closing out file channels. Error handler sets flag to prevent any further audio wave recorders from being started and logs the same.	2015-12-13 09:01:29 -05:00
denny	98c70a1b12	Resolved issue with wave recorders not shutting down correctly, causing ... errors with max file handles is exceeded.	2015-12-11 21:33:20 -05:00
denny	a6c7c4f5d1	P25 Decoder updates - work in progress. ... Updated jmbe library to work with version 0.3.1	2015-11-15 19:53:42 -05:00
denny	9c69733034	Decouples DecoderState from the Decoder and makes DecoderState inherit ... from Module so that Decoder can function independent of DecoderSTate and DecoderState can more cleanly interface with other modules. Resolves issue with LTR-type decoders where the AudioModule was filtering demodulated audio buffers before the decoder received the audio - demodulated audio buffers are now copied before creating AudioPackets.	2015-09-26 05:45:34 -04:00
denny	732d478502	Resolved timing issue in wave writer	2015-09-13 06:18:46 -04:00
denny	575197bd98	Interim checkin for call recording.	2015-09-11 14:01:47 -04:00
denny	0f85b7260a	Adds event logging, code cleanup and some decoder issue resolution.	2015-09-02 19:41:44 -04:00
denny	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	2015-09-01 07:10:26 -04:00
