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. |

Convert multiplier for MV from int to ptrdiff_t.
This prevents emulated_edge_mc from not undoing mvy*stride-related integer overflows. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> |

avcodec: add emuedge_linesize_type
Currently all uses of the emu edge code as well as the code itself assume int linesize changing some but not changing all would introduce a security issue once all use this typedef a simple search and replace can be done to switch them all to ptrdiff_t Signed-off-by: Michael Niedermayer <michaelni@gmx.at> |

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> |
