variables again to let the threads end normally. Re-implenented the method
closewaveoutput() for some modules, move the destructor code to it and call it
after leaving the mixer thread. This fixes a deadlock in the "soundwin" module
if Bochs is compiled with plugin support.
- Implemented wave output using the 'soundfile' driver including dual wave
output in wavemode 3. Removed now obsolete output file handling and other
cleanups. The wave input (recording) feature is not affected by the
wavemode setting.
- Moved VOC file handling to the soundfile code.
- Updated iodev makefile dependencies.
- soundlow: use direct output if no PCM callback is registered.
- soundlow/soundfile: re-implemented openwaveoutput() method to support
runtime changes of wave mode or file (only implemented in the 'file'
driver, stub for others).
- soundfile: don't initialize mixer thread and PCM callback if thread is
already running / no output() delay in that case.
- Added the capability to load up to 4 sound drivers and added methods to
get pointers to the waveout, wavein and midiout services of a driver.
- Rewrite of the SB16 midi file output code. In midimode 2 and 3 the midiout
service of the 'file' driver is used. Removed obsolete midi file handling.
- Re-implemented the closemidioutput() method to make runtime changes of the
midi setup work with the new code.
- waveout: added support for RIFF WAVE format and raw output. The formats
'voc' and 'wav' are detected by file extension, raw output is used otherwise.
- midiout: added support for raw midi output (no header, no deltatime).
The 'mid' format is detected by file extension, raw output is used otherwise.
- Added 'midiout' parameter to the global sound option to specify the device
if necessary. The related SB16 parameter now only specifies the output file.
- TODO: Rewrite of the sound configuration and output code to support dual
output (device and file).
- New code is based on the dummy sound driver and file output code from SB16.
- The midiout feature supports the MIDI file format.
- The waveout feature currently only supports the VOC format.
TODO:
- Add support for a more detailed sound configuration (waveout to device,
midiout to a file.
- The waveout feature should support WAV and RAW file formats.
- Move VOC file handling from soundmod.cc to soundfile.cc.
- Finally remove file handling code from sound devices.
