From 9b7ec42403073ee887efc531c153e6b1b6c15bab Mon Sep 17 00:00:00 2001 From: Nils Wallménius Date: Sun, 19 Jan 2014 16:31:59 +0100 Subject: Sync to upstream libopus Sync to commit bb4b6885a139644cf3ac14e7deda9f633ec2d93c This brings in a bunch of optimizations to decode speed and memory usage. Allocations are switched from using the pseudostack to using the real stack. Enabled hacks to reduce stack usage. This should fix crashes on sansa clip, although some files will not play due to failing allocations in the codec buffer. Speeds up decoding of the following test files: H300 (cf) C200 (arm7tdmi) ipod classic (arm9e) 16 kbps (silk) 14.28 MHz 4.00 MHz 2.61 MHz 64 kbps (celt) 4.09 MHz 8.08 MHz 6.24 MHz 128 kbps (celt) 1.93 MHz 8.83 MHz 6.53 MHz Change-Id: I851733a8a5824b61feb363a173091bc7e6629b58 --- lib/rbcodec/codecs/libopus/celt/bands.h | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) (limited to 'lib/rbcodec/codecs/libopus/celt/bands.h') diff --git a/lib/rbcodec/codecs/libopus/celt/bands.h b/lib/rbcodec/codecs/libopus/celt/bands.h index 96ba52a649..69901b1e33 100644 --- a/lib/rbcodec/codecs/libopus/celt/bands.h +++ b/lib/rbcodec/codecs/libopus/celt/bands.h @@ -41,7 +41,7 @@ * @param X Spectrum * @param bandE Square root of the energy for each band (returned) */ -void compute_band_energies(const CELTMode *m, const celt_sig *X, celt_ener *bandE, int end, int C, int M); +void compute_band_energies(const CELTMode *m, const celt_sig *X, celt_ener *bandE, int end, int C, int LM); /*void compute_noise_energies(const CELTMode *m, const celt_sig *X, const opus_val16 *tonality, celt_ener *bandE);*/ @@ -59,14 +59,15 @@ void normalise_bands(const CELTMode *m, const celt_sig * OPUS_RESTRICT freq, cel * @param bandE Square root of the energy for each band */ void denormalise_bands(const CELTMode *m, const celt_norm * OPUS_RESTRICT X, - celt_sig * OPUS_RESTRICT freq, const opus_val16 *bandE, int start, int end, int C, int M); + celt_sig * OPUS_RESTRICT freq, const opus_val16 *bandE, int start, + int end, int M, int downsample, int silence); #define SPREAD_NONE (0) #define SPREAD_LIGHT (1) #define SPREAD_NORMAL (2) #define SPREAD_AGGRESSIVE (3) -int spreading_decision(const CELTMode *m, celt_norm *X, int *average, +int spreading_decision(const CELTMode *m, const celt_norm *X, int *average, int last_decision, int *hf_average, int *tapset_decision, int update_hf, int end, int C, int M); @@ -104,8 +105,8 @@ void quant_all_bands(int encode, const CELTMode *m, int start, int end, opus_int32 total_bits, opus_int32 balance, ec_ctx *ec, int M, int codedBands, opus_uint32 *seed); void anti_collapse(const CELTMode *m, celt_norm *X_, unsigned char *collapse_masks, int LM, int C, int size, - int start, int end, opus_val16 *logE, opus_val16 *prev1logE, - opus_val16 *prev2logE, int *pulses, opus_uint32 seed); + int start, int end, const opus_val16 *logE, const opus_val16 *prev1logE, + const opus_val16 *prev2logE, const int *pulses, opus_uint32 seed); opus_uint32 celt_lcg_rand(opus_uint32 seed); -- cgit v1.2.3
