lavc: Edge emulation with dst/src linesize
Allow supporting files for which the image stride is smaller than the maximum block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge. |

avcodec/x86/videodsp: Small speedups in ff_emulated_edge_mc x86 SIMD.
Don't use word-size multiplications if size == 2, and if we're using SIMD instructions (size >= 8), complete leftover 4byte sets using movd, not mov. Both of these changes lead to minor speedups. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> |

avcodec/x86/videodsp: Properly mark sse2 instructions in emulated_edge_mc x86 simd as such.
Should fix crashes or corrupt output on pre-SSE2 CPUs when they were using SSE2-code (e.g. AMD Athlon XP 2400+ or Intel Pentium III) in hfix or hvar single-edge (left/right) extension functions. Tested-by: Ingo Brückl <ib@wupperonline.de> Signed-off-by: Michael Niedermayer <michaelni@gmx.at> |

Rewrite emu_edge functions to have separate src/dst_stride arguments.
This allows supporting files for which the image stride is smaller than the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge. |

lavc: introduce VideoDSPContext
Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch(). Signed-off-by: Luca Barbato <lu_zero@gentoo.org> |
