macOS has no OSS (/dev/dsp) support, but dsd-fme currently compiles and links OSS code unconditionally, leading to build and link failures.
This PR:
* disables OSS backend cleanly on macOS
* provides a no-op openOSSOutput() stub to satisfy callers
* guards OSS-specific headers and ioctl usage
* preserves existing behavior on Linux/OSS platforms
This allows dsd-fme to build and run correctly on macOS using PulseAudio/CoreAudio paths.
This does not include DES-XL due to needing to know HDU or LDU2 and complications of SDRtrunk P1 ESS handling, and also unknown Phase 2 method for XL.
Nor TDEA (never observed on P25 despite in spec);
Use sed to replace line in ITPP CmakeLists.txt file to update the cmake_minimum_required to an acceptible version for newer cmake;
Include SIMD Math Libraries libopenblas, liblapack-devel, libfftw3-devel for Cygwin64;
If perceived performance issues arise, may consider removing the Math Libraries above from Cygwin64 install script
Fix cyg_portable.sh for newest version of Cygwin64;
Fix p25_frequency process_channel_to_freq to allow a channel value of (0000);
Fix Event Format Nit and add EOT Delay on CC for EDACS/PV;
Using -* exhibits unusual behavior and may read contents of directory and set any value based on what is in there;
Don't use for future CLI arguments;
Update Usage;
This is primarily a fix for those CCR Radios that use the static silence frame and doesn't encrypt it either at the start of, or end of TX;
The Zeroes Fix (000D2C00000000) is for Anytone or TXI who has a load of zeroes starting, or ending a TX, or during the TXI window on certain VC-F frames;
NXDN: Redo NXDN VCALL_ARIB based on observed values and ARIB STD-B54;
Add UTF16 to UTF8 encoding for DMR Talker Alias when its UTF16;
Encoding Unicode / UTF16 to UTF8 Allows for display into Ncurses Terminal, Event History, etc when its CJK and not normal ISO7/ ASCII or UTF8 encoded as UTF16;
Might be beneficial to convert and run all encoded text through UTF8 encode in the future.
MBE: Make tweaks to audio and wav file handling, allow writing to static wav files even if audio out device is NULL (writeSynthesizedVoiceMS);
DSTAR: Fix Issue with DSTAR where double writes would occur in single static .wav files;
Adding a new method to allow a user to enter a generic keystream len and static keystream via a string that is loaded into a bit array to xor against ambe frames;
This method is intended to be used to allow
Reset static_ks_counter as various places in code;
Remove the static_ks_counter reset from KWD SCR link control and tweak SO bits;
Fix Forced KS application to work in both slots;
Allow Static Wav File or Per Call Wav File in SDRTrunk MBE format playback; #298
Same as above for .amb, .dmb, and .imb format playback;
Update Usage and Docs;
Fix Per Call Issue introduced with commit re-enabling single static wav file where single channel audio decode types would not write to per call temp wav files and be deleted after event history cycled them;
Fix Issue with YSF where double writes would occur in .wav files;
Fix Issue with M17 where incorrect rate audio would write to static .wav file by converting to stereo output;
Seperate Per Call and Create Method to Allow EDACS Analog Calls to be written to static wav file by downsampling and stereo interleaving audio to proper spec;
Issues were introduced in commit # c7b25c60af
