Rémi Denis-Courmont	a6c10d05fe	lavu/floatdsp: RISC-V V vector_fmul_scalar This is based on existing code from the VLC git tree with two minor changes to account for the different function prototypes.	2 years ago
Rémi Denis-Courmont	04d092e7d5	lavc/audiodsp: RISC-V F vector_clipf RV64G supports MIN & MAX instructions natively only on floating point registers, not general purpose ones. The later would require the Zbb extension. Due to that, it is actually faster to perform the clipping "properly" in FPU. Benchmarks on SiFive U74-MC (courtesy of Shanghai StarFive Tech): audiodsp.vector_clipf_c: 29551.5 audiodsp.vector_clipf_rvf: 17871.0 Also tried unrolling with 2 or 8 elements but it gets worse either way.	2 years ago
Diego Biurrun	9a9e2f1c8a	dsputil: Split audio operations off into a separate context	11 years ago
Ben Avison	9d8ecdd8ca	vc-1: Add platform-specific start code search routine to VC1DSPContext. Initialise VC1DSPContext for parser as well as for decoder. Note, the VC-1 code doesn't actually use the function pointer yet. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Mason Carter	832e190632	vc1: arm: Add NEON assembly For: ff_vc1_inv_trans_{8,4}x{8,4}_{dc_,}neon ff_put_pixels8x8_neon ff_put_vc1_mspel_mc{0,1,2,3}{0,1,2,3}_neon (except for 00) Based on ARM assembly code in libavcodec/arm by Rob Clark and Mans Rullgard.

Diego Biurrun	73b704ac60	arm: Add some missing header #includes	12 years ago
Mans Rullgard	b692d246ea	vp8: arm: separate ARMv6 functions from NEON This is a preparation for complete ARMv6 optimisations. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	d526c5338d	ARM: allow runtime masking of CPU features This allows masking CPU features with the -cpuflags avconv option which is useful for testing different optimisations without rebuilding. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Michael Niedermayer	c266eb1928	arm: Fix 10l typo Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Ronald S. Bultje	bd66f073fe	vp8: change int stride to ptrdiff_t stride. On 64bit platforms with 32bit int, this means we won't have to sign- extend the integer anymore.	13 years ago
Diego Biurrun	32f3c541bc	doxygen: Do not include license boilerplates in Doxygen comment blocks.	13 years ago
Ronald S. Bultje	a5dfeb612e	VP8: armv6 optimizations. From 52.503s (~40fps) to 27.973sec (~80fps) decoding of 480p sintel trailer, i.e. a ~2x speedup overall, on a Nexus S. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
