Michael Niedermayer	b50559fc0b	libavcodec/x86/dsputilenc: drop and 0xffff that should have becomei redundant Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
James Almer	561bfc85eb	x86/dsputilenc: implement SSE2 versions of pix_{sum16, norm1} Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Christophe Gisquet	0810608e23	x86: hevc_mc: better register allocation The xmm reg count was incorrect, and manual loading of the gprs furthermore allows to noticeable reduce the number needed. The modified functions are used in weighted prediction, so only a few samples like WP_* exhibit a change. For this one and Win64 (some widths removed because of too few occurrences): WP_A_Toshiba_3.bit, ff_hevc_put_hevc_uni_w 16 32 before: 2194 3872 after: 2119 3767 WP_B_Toshiba_3.bit, ff_hevc_put_hevc_bi_w 16 32 64 before: 2819 4960 9396 after: 2617 4788 9150 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

Diego Biurrun	b5aa485513	ppc: Move vec_unaligned_load macro to util_altivec This allows reusing it from multiple files.	11 years ago
Anton Khirnov	5fdaf312c5	flac: make avpriv_flac_parse_block_header() inline This avoids all the ABI troubles associated with avpriv_. Since this function is very small and does not depend on any tables, making it inline should have no adverse effects.	11 years ago
Anton Khirnov	f13ffb6636	flacdec: do not overwrite a channel layout set by the caller The channel layout mask for non-standard layouts is typically stored at the container level (as a vorbiscomment tag) for FLAC.	11 years ago
