However, it did not set msbc private flag, which is checked e.g. by sbc_set_defaults() and sbc_get_frame_length() functions. This commit fixes this, so now after reinitialization this library properly packs/unpacks mSBC frames and the sbc_get_frame_length() function returns correct frame length. --- sbc/sbc.c | 71 ++++++++++++++++++++++++++----------------------------- 1 file changed, 33 insertions(+), 38 deletions(-) diff --git a/sbc/sbc.c b/sbc/sbc.c index d059906..c35b564 100644 --- a/sbc/sbc.c +++ b/sbc/sbc.c @@ -1010,17 +1010,13 @@ static void sbc_set_defaults(sbc_t *sbc, unsigned long flags) { struct sbc_priv *priv = sbc->priv; - if (priv->msbc) { - priv->pack_frame = msbc_pack_frame; - priv->unpack_frame = msbc_unpack_frame; - } else { - priv->pack_frame = sbc_pack_frame; - priv->unpack_frame = sbc_unpack_frame; - } + priv->pack_frame = sbc_pack_frame; + priv->unpack_frame = sbc_unpack_frame; sbc->flags = flags; sbc->frequency = SBC_FREQ_44100; sbc->mode = SBC_MODE_STEREO; + sbc->allocation = SBC_AM_LOUDNESS; sbc->subbands = SBC_SB_8; sbc->blocks = SBC_BLK_16; sbc->bitpool = 32; @@ -1033,6 +1029,30 @@ static void sbc_set_defaults(sbc_t *sbc, unsigned long flags) #endif } +static void sbc_set_defaults_msbc(sbc_t *sbc, unsigned long flags) +{ + struct sbc_priv *priv = sbc->priv; + + priv->msbc = true; + priv->pack_frame = msbc_pack_frame; + priv->unpack_frame = msbc_unpack_frame; + + sbc->flags = flags; + sbc->frequency = SBC_FREQ_16000; + sbc->mode = SBC_MODE_MONO; + sbc->allocation = SBC_AM_LOUDNESS; + sbc->subbands = SBC_SB_8; + sbc->blocks = MSBC_BLOCKS; + sbc->bitpool = 26; +#if __BYTE_ORDER == __LITTLE_ENDIAN + sbc->endian = SBC_LE; +#elif __BYTE_ORDER == __BIG_ENDIAN + sbc->endian = SBC_BE; +#else +#error "Unknown byte order" +#endif +} + SBC_EXPORT int sbc_init(sbc_t *sbc, unsigned long flags) { if (!sbc) @@ -1056,33 +1076,13 @@ SBC_EXPORT int sbc_init(sbc_t *sbc, unsigned long flags) SBC_EXPORT int sbc_init_msbc(sbc_t *sbc, unsigned long flags) { - struct sbc_priv *priv; - - if (!sbc) - return -EIO; - - memset(sbc, 0, sizeof(sbc_t)); - - sbc->priv_alloc_base = malloc(sizeof(struct sbc_priv) + SBC_ALIGN_MASK); - if (!sbc->priv_alloc_base) - return -ENOMEM; - - sbc->priv = (void *) (((uintptr_t) sbc->priv_alloc_base + - SBC_ALIGN_MASK) & ~((uintptr_t) SBC_ALIGN_MASK)); - - memset(sbc->priv, 0, sizeof(struct sbc_priv)); - - priv = sbc->priv; - priv->msbc = true; + int err; - sbc_set_defaults(sbc, flags); + err = sbc_init(sbc, flags); + if (err < 0) + return err; - sbc->frequency = SBC_FREQ_16000; - sbc->blocks = MSBC_BLOCKS; - sbc->subbands = SBC_SB_8; - sbc->mode = SBC_MODE_MONO; - sbc->allocation = SBC_AM_LOUDNESS; - sbc->bitpool = 26; + sbc_set_defaults_msbc(sbc, flags); return 0; } @@ -1095,12 +1095,7 @@ SBC_EXPORT int sbc_reinit_msbc(sbc_t *sbc, unsigned long flags) if (err < 0) return err; - sbc->frequency = SBC_FREQ_16000; - sbc->blocks = MSBC_BLOCKS; - sbc->subbands = SBC_SB_8; - sbc->mode = SBC_MODE_MONO; - sbc->allocation = SBC_AM_LOUDNESS; - sbc->bitpool = 26; + sbc_set_defaults_msbc(sbc, flags); return 0; }
