Christophe Gisquet	57b1eb9f75	dcadsp: scan coefficients linearly in dca_lfe_fir This change is inspired by x86 asm where it frees a register. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Christophe Gisquet	ad507d7907	x86: dcadsp: implement SSE lfe_dir Results for Arrandale/Windows: 32: 1670 -> 316 64: 728 -> 298 Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Christophe Gisquet	87ec849fe9	dcadec: remove scaling in lfe_interpolation_fir The scaling factor is constant so it is faster to scale the FIR coefficients in the tables during compilation. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago

James Almer	fbf98375e4	x86/imdct36: don't build imdct36_float_sse on x86_64 targets There's an SSE2 version as well, and x86_64 guarantees that instruction set is present.

Michael Niedermayer	6904168c79	avcodec/mjpegdec: Print error in case of CMYK Also fail if AV_EF_EXPLODE is set. We do not fail by default, but rather return some image as it may be usefull to the end user to see what is on the image, for example text could be read quite fine and objects recognized.

James Almer	3f3d748cab	x86: Move XOP emulation to x86util We need the emulation to support the cases where the first argument is the same as the fourth. To achieve this a fifth argument working as a temporary may be needed. Emulation that doesn't obey the original instruction semantics can't be in x86inc.
