- added Android case to the configure script.
- renamed file memory.h to memory-bochs.h to fix conflict with NDK.
- fixed Android issues in some files.
sendwavepacket() directly calls the conversion method and output(). In all other
cases it puts the unmodified data into a buffer and the conversion thread is
doing the main job and puts the data into the output buffer chain.
TODO: resampling could also be done by the new thread.
NULL for all services and the dummy driver provides the stubs. Now falling
back to the dummy driver if the wavein or midiout services are not provided
by the selected driver.
- 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.
creates the object and returns a pointer to it. TODO: Rewrite of the sound
configuration to support a more detailed setup (e.g. waveout with alsa,
dummy wavein, midiout to a file).
creates the object and returns a pointer to it. TODO: The wavein and midiout
components should also move to separate classes. When finished, it should be
possible to configure the sound support more detailed (e.g. waveout with sdl,
midiout with alsa and the dummy driver for wavein). Creating a separate
module for the output to file(s) is also possible.
- soundlow: prepared code for 2 pcm parameter sets:
emulated: requested by sendwavepacket()
real: used for the sound output
- soundsdl: startwaveplayback() rewritten to set_pcm_data().
- soundmod: some beep init code fixes.
- OPL3: Added support to change the samplerate of the generator.
- SDL sound: convert wave packet to 16 Bit signed stereo format.
- Increased the maximum size of a single wave packet for playbck/recording.
- Define new structure bx_pcm_param_t and use it as a parameter for the method
sendwavepacket(). The method startwavepacket() is now called from
sendwavepacket() in case of a parameter change (temporary solution).
- soundsdl: Replaced waveready() call by some more accurate code for buffer
space check in sendwavepacket().
- soundsdl: Moved code for reading from audio buffer to a new function.
- soundsdl: Temporarily increase the audio buffer size.
- Preparing the SB16 code for the OPL emulation port from DOSBox.
- Reworked wave callback code to support 2 input sources (no mixing yet).
- Fixed SDL sound output.
- Beep generator fixes.
- Prepared the SB16 code for FM OPL output support (to be ported from DOSBox).
- Renamed wavedata callback type.
- Handle sample rate in the beep generator (TODO: handle data format).
- Don't call waveready() in the SB16 code.
- Attempt to fix SDL2 wave output using SDL_LockAudio() / SDL_UnlockAudio().
- SDL specific code in the beep thread no longer needed.
- Added framework for polling wave data and use it for beep output in sdl.
- Some work in the beep thread code (to be continued).
- Moved macros required for multithreading to bochs.h.
