rockbox/firmware/target/hosted/android/pcm-android.c, branch working

Do not include kernel.h in system.h.

2014-01-05T18:35:23+00:00

system.h doesn't need it on its own and this change makes it less
dependant on Rockbox internals.

android: Rewrite PCM playback without OnPlaybackPositionUpdateListener.

2013-04-01T09:26:12+00:00

The old way actually mis-used the API (I misunderstood the docs) because
it specified the marker position as a "low buffer watermark" but instead of a
future playback head position.

The replacement is a simple thread that writes the data regardless of the
filling level of the buffer (write() will just block) and polls the playback
state periodically.

Tweak some PCM drivers for less typecasting with the data pointer.

Yeah, sizeof (void) here with GCC is 1. If something has a problem
with that, we'll set it straight.

Revise the PCM callback system after adding multichannel audio.

2012-03-03T06:23:38+00:00

Additional status callback is added to pcm_play/rec_data instead of
using a special function to set it. Status includes DMA error
reporting to the status callback. Playback and recording callback
become more alike except playback uses "const void **addr" (because
the data should not be altered) and recording  uses "void **addr".
"const" is put in place throughout where appropriate.

Most changes are fairly trivial. One that should be checked in
particular because it isn't so much is telechips, if anyone cares to
bother. PP5002 is not so trivial either but that tested as working.

Shuffle some functions around so that interfacing with playback.c in particular isn't required. Though playback does finish the audio init, pcm doesn't care who does it.

Commit FS#12150 - Fully-functional audio mixer - and finally whip old limitations about playback of voice and other sounds when paused. Channels are independent in state and amplitude. Fade on stop/pause is handled by the channel's volume control rather than global volume which means it now works from anywhere. Opens up the possibility of plugin sounds during music playback by merely adding an additional channel enum. If any PCM drivers were not properly modified, see one of the last comments in the task for a description of the simple change that is expected. Some params are tunable in firmware/export/pcm-mixer.h as well.

Android: Greatly simplify the pcm callback mechanism on both, the Java and the C side. Should be more reliable now (if the old wasn't already).
