From f993365447d8dc5bb28c76a003cecd045c3abaf7 Mon Sep 17 00:00:00 2001 From: Jörg Hohensohn Date: Mon, 5 Jan 2004 20:42:51 +0000 Subject: Moved the low-level playback functionality into a new, separate module "mp3_playback". This e.g. allows to export a memory playback API to the plugins, opens the door to games with sound, UI sounds, etc. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@4192 a1c6a512-1295-4272-9138-f99709370657 --- firmware/export/mp3_playback.h | 73 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 73 insertions(+) create mode 100644 firmware/export/mp3_playback.h (limited to 'firmware/export/mp3_playback.h') diff --git a/firmware/export/mp3_playback.h b/firmware/export/mp3_playback.h new file mode 100644 index 0000000000..2767092b75 --- /dev/null +++ b/firmware/export/mp3_playback.h @@ -0,0 +1,73 @@ +/*************************************************************************** + * __________ __ ___. + * Open \______ \ ____ ____ | | _\_ |__ _______ ___ + * Source | _// _ \_/ ___\| |/ /| __ \ / _ \ \/ / + * Jukebox | | ( <_> ) \___| < | \_\ ( <_> > < < + * Firmware |____|_ /\____/ \___ >__|_ \|___ /\____/__/\_ \ + * \/ \/ \/ \/ \/ + * $Id$ + * + * Code that has been in mpeg.c/h before, now creating an encapsulated play + * data module, to be used by other sources than file playback as well. + * + * Copyright (C) 2004 by Linus Nielsen Feltzing + * + * All files in this archive are subject to the GNU General Public License. + * See the file COPYING in the source tree root for full license agreement. + * + * This software is distributed on an "AS IS" basis, WITHOUT WARRANTY OF ANY + * KIND, either express or implied. + * + ****************************************************************************/ +#ifndef _MP3_PLAYBACK_H_ +#define _MP3_PLAYBACK_H_ + +#include + +/* functions formerly in mpeg.c */ +void mp3_init(int volume, int bass, int treble, int balance, + int loudness, int bass_boost, int avc, int channel_config); +void mpeg_sound_set(int setting, int value); +int mpeg_sound_min(int setting); +int mpeg_sound_max(int setting); +int mpeg_sound_default(int setting); +void mpeg_sound_channel_config(int configuration); +int mpeg_val2phys(int setting, int value); +int mpeg_phys2val(int setting, int value); +char *mpeg_sound_unit(int setting); +int mpeg_sound_numdecimals(int setting); +#if defined(HAVE_MAS3587F) || defined(SIMULATOR) +void mpeg_set_pitch(int percent); +#endif + +/* new functions, to be exported to plugin API */ +void mp3_play_init(void); +void mp3_play_data(unsigned char* start, int size, + void (*get_more)(unsigned char** start, int* size) /* callback fn */ +); +void mp3_play_pause(bool play); +void mp3_play_stop(void); + + +#define SOUND_VOLUME 0 +#define SOUND_BASS 1 +#define SOUND_TREBLE 2 +#define SOUND_BALANCE 3 +#define SOUND_LOUDNESS 4 +#define SOUND_SUPERBASS 5 +#define SOUND_AVC 6 +#define SOUND_CHANNELS 7 +#define SOUND_LEFT_GAIN 8 +#define SOUND_RIGHT_GAIN 9 +#define SOUND_MIC_GAIN 10 +#define SOUND_NUMSETTINGS 11 + +#define MPEG_SOUND_STEREO 0 +#define MPEG_SOUND_STEREO_NARROW 1 +#define MPEG_SOUND_MONO 2 +#define MPEG_SOUND_MONO_LEFT 3 +#define MPEG_SOUND_MONO_RIGHT 4 +#define MPEG_SOUND_KARAOKE 5 +#define MPEG_SOUND_STEREO_WIDE 6 + +#endif /* #ifndef _MP3_PLAYBACK_H_ */ -- cgit v1.2.3
