From 46ae64cd60166ead412bacc1bf03e9c8f8965e2c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?R=C3=A9mi=20Verschelde?= Date: Mon, 18 Nov 2019 09:56:18 +0100 Subject: Revert "Update opus to 1.3.1 and opusfile to 0.11" This reverts commit e00426c512a7905f5f925d382c443bab7a0ca693. The way we handle platform-specific intrinsics is not good, so the current state will not compile on armv8. This commit also requires SSE4.1 support, which is likely not a good idea for portable binaries. We'll have to redo this with more caution after 3.2 is released, or we might simply drop opus as we're only using it as dependency for theora right now. Fixes #33606. --- thirdparty/opus/silk/A2NLSF.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'thirdparty/opus/silk/A2NLSF.c') diff --git a/thirdparty/opus/silk/A2NLSF.c b/thirdparty/opus/silk/A2NLSF.c index b487686ff9..b6e9e5ffcc 100644 --- a/thirdparty/opus/silk/A2NLSF.c +++ b/thirdparty/opus/silk/A2NLSF.c @@ -40,7 +40,7 @@ POSSIBILITY OF SUCH DAMAGE. /* Number of binary divisions, when not in low complexity mode */ #define BIN_DIV_STEPS_A2NLSF_FIX 3 /* must be no higher than 16 - log2( LSF_COS_TAB_SZ_FIX ) */ -#define MAX_ITERATIONS_A2NLSF_FIX 16 +#define MAX_ITERATIONS_A2NLSF_FIX 30 /* Helper function for A2NLSF(..) */ /* Transforms polynomials from cos(n*f) to cos(f)^n */ @@ -130,7 +130,7 @@ void silk_A2NLSF( const opus_int d /* I Filter order (must be even) */ ) { - opus_int i, k, m, dd, root_ix, ffrac; + opus_int i, k, m, dd, root_ix, ffrac; opus_int32 xlo, xhi, xmid; opus_int32 ylo, yhi, ymid, thr; opus_int32 nom, den; @@ -239,13 +239,13 @@ void silk_A2NLSF( /* Set NLSFs to white spectrum and exit */ NLSF[ 0 ] = (opus_int16)silk_DIV32_16( 1 << 15, d + 1 ); for( k = 1; k < d; k++ ) { - NLSF[ k ] = (opus_int16)silk_ADD16( NLSF[ k-1 ], NLSF[ 0 ] ); + NLSF[ k ] = (opus_int16)silk_SMULBB( k + 1, NLSF[ 0 ] ); } return; } /* Error: Apply progressively more bandwidth expansion and run again */ - silk_bwexpander_32( a_Q16, d, 65536 - silk_LSHIFT( 1, i ) ); + silk_bwexpander_32( a_Q16, d, 65536 - silk_SMULBB( 10 + i, i ) ); /* 10_Q16 = 0.00015*/ silk_A2NLSF_init( a_Q16, P, Q, dd ); p = P; /* Pointer to polynomial */ -- cgit v1.2.3
