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/silk/decode_frame.c | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) (limited to 'lib/rbcodec/codecs/libopus/silk/decode_frame.c') diff --git a/lib/rbcodec/codecs/libopus/silk/decode_frame.c b/lib/rbcodec/codecs/libopus/silk/decode_frame.c index abc00a3d54..6a7cffbbe0 100644 --- a/lib/rbcodec/codecs/libopus/silk/decode_frame.c +++ b/lib/rbcodec/codecs/libopus/silk/decode_frame.c @@ -47,13 +47,10 @@ opus_int silk_decode_frame( { VARDECL( silk_decoder_control, psDecCtrl ); opus_int L, mv_len, ret = 0; - VARDECL( opus_int, pulses ); SAVE_STACK; L = psDec->frame_length; ALLOC( psDecCtrl, 1, silk_decoder_control ); - ALLOC( pulses, (L + SHELL_CODEC_FRAME_LENGTH - 1) & - ~(SHELL_CODEC_FRAME_LENGTH - 1), opus_int ); psDecCtrl->LTP_scale_Q14 = 0; /* Safety checks */ @@ -62,6 +59,9 @@ opus_int silk_decode_frame( if( lostFlag == FLAG_DECODE_NORMAL || ( lostFlag == FLAG_DECODE_LBRR && psDec->LBRR_flags[ psDec->nFramesDecoded ] == 1 ) ) { + VARDECL( opus_int16, pulses ); + ALLOC( pulses, (L + SHELL_CODEC_FRAME_LENGTH - 1) & + ~(SHELL_CODEC_FRAME_LENGTH - 1), opus_int16 ); /*********************************************/ /* Decode quantization indices of side info */ /*********************************************/ @@ -107,16 +107,16 @@ opus_int silk_decode_frame( silk_memmove( psDec->outBuf, &psDec->outBuf[ psDec->frame_length ], mv_len * sizeof(opus_int16) ); silk_memcpy( &psDec->outBuf[ mv_len ], pOut, psDec->frame_length * sizeof( opus_int16 ) ); - /****************************************************************/ - /* Ensure smooth connection of extrapolated and good frames */ - /****************************************************************/ - silk_PLC_glue_frames( psDec, pOut, L ); - /************************************************/ /* Comfort noise generation / estimation */ /************************************************/ silk_CNG( psDec, psDecCtrl, pOut, L ); + /****************************************************************/ + /* Ensure smooth connection of extrapolated and good frames */ + /****************************************************************/ + silk_PLC_glue_frames( psDec, pOut, L ); + /* Update some decoder state variables */ psDec->lagPrev = psDecCtrl->pitchL[ psDec->nb_subfr - 1 ]; -- cgit v1.2.3
