typedef int(* | FishSoundDecoded_Float )(FishSound *fsound, float *pcm[], long frames, void *user_data) |
Signature of a callback for libfishsound to call when it has decoded PCM audio data, and you want this provided as non-interleaved floats. | |
typedef int(* | FishSoundDecoded_FloatIlv )(FishSound *fsound, float **pcm, long frames, void *user_data) |
Signature of a callback for libfishsound to call when it has decoded PCM audio data, and you want this provided as interleaved floats. | |
Functions | |
int | fish_sound_set_decoded_float (FishSound *fsound, FishSoundDecoded_Float decoded, void *user_data) |
Set the callback for libfishsound to call when it has a block of decoded PCM audio ready, and you want this provided as non-interleaved floats. | |
int | fish_sound_set_decoded_float_ilv (FishSound *fsound, FishSoundDecoded_FloatIlv decoded, void *user_data) |
Set the callback for libfishsound to call when it has a block of decoded PCM audio ready, and you want this provided as interleaved floats. | |
long | fish_sound_decode (FishSound *fsound, unsigned char *buf, long bytes) |
Decode a block of compressed data. |
Decode functions and callback prototypes.
typedef int(* FishSoundDecoded_Float)(FishSound *fsound, float *pcm[], long frames, void *user_data) |
Signature of a callback for libfishsound to call when it has decoded PCM audio data, and you want this provided as non-interleaved floats.
fsound | The FishSound* handle |
pcm | The decoded audio |
frames | The count of frames decoded |
user_data | Arbitrary user data |
FISH_SOUND_CONTINUE | Continue decoding |
FISH_SOUND_STOP_OK | Stop decoding immediately and return control to the fish_sound_decode() caller |
FISH_SOUND_STOP_ERR | Stop decoding immediately, purge buffered data, and return control to the fish_sound_decode() caller |
typedef int(* FishSoundDecoded_FloatIlv)(FishSound *fsound, float **pcm, long frames, void *user_data) |
Signature of a callback for libfishsound to call when it has decoded PCM audio data, and you want this provided as interleaved floats.
fsound | The FishSound* handle |
pcm | The decoded audio |
frames | The count of frames decoded |
user_data | Arbitrary user data |
FISH_SOUND_CONTINUE | Continue decoding |
FISH_SOUND_STOP_OK | Stop decoding immediately and return control to the fish_sound_decode() caller |
FISH_SOUND_STOP_ERR | Stop decoding immediately, purge buffered data, and return control to the fish_sound_decode() caller |
long fish_sound_decode | ( | FishSound * | fsound, |
unsigned char * | buf, | ||
long | bytes | ||
) |
Decode a block of compressed data.
No internal buffering is done, so a complete compressed audio packet must be passed each time.
fsound | A FishSound* handle (created with mode FISH_SOUND_DECODE) |
buf | A buffer containing a compressed audio packet |
bytes | A count of bytes to decode (i.e. the length of buf) |
FISH_SOUND_ERR_STOP_OK | Decoding was stopped by a FishSoundDecode* callback returning FISH_SOUND_STOP_OK before any input bytes were consumed. This will occur when PCM is decoded from previously buffered input, and stopping is immediately requested. |
FISH_SOUND_ERR_STOP_ERR | Decoding was stopped by a FishSoundDecode* callback returning FISH_SOUND_STOP_ERR before any input bytes were consumed. This will occur when PCM is decoded from previously buffered input, and stopping is immediately requested. |
FISH_SOUND_ERR_BAD | Not a valid FishSound* handle |
FISH_SOUND_ERR_OUT_OF_MEMORY | Out of memory |
int fish_sound_set_decoded_float | ( | FishSound * | fsound, |
FishSoundDecoded_Float | decoded, | ||
void * | user_data | ||
) |
Set the callback for libfishsound to call when it has a block of decoded PCM audio ready, and you want this provided as non-interleaved floats.
fsound | A FishSound* handle (created with mode FISH_SOUND_DECODE) |
decoded | The callback to call |
user_data | Arbitrary user data to pass to the callback |
0 | Success |
FISH_SOUND_ERR_BAD | Not a valid FishSound* handle |
FISH_SOUND_ERR_OUT_OF_MEMORY | Out of memory |
int fish_sound_set_decoded_float_ilv | ( | FishSound * | fsound, |
FishSoundDecoded_FloatIlv | decoded, | ||
void * | user_data | ||
) |
Set the callback for libfishsound to call when it has a block of decoded PCM audio ready, and you want this provided as interleaved floats.
fsound | A FishSound* handle (created with mode FISH_SOUND_DECODE) |
decoded | The callback to call |
user_data | Arbitrary user data to pass to the callback |
0 | Success |
FISH_SOUND_ERR_BAD | Not a valid FishSound* handle |
FISH_SOUND_ERR_OUT_OF_MEMORY | Out of memory |
