aarch64: hevc_idct: Fix overflows in idct_dc
This is marginally slower, but correct for all input values. The previous implementation failed with certain input seeds, e.g. "checkasm --test=hevc_idct 98". Signed-off-by: Martin Storsjö <martin@martin.st> |

lavc/aarch64: port HEVC add_residual NEON
Speedup is fairly small, around 1.5%, but these are fairly simple. Signed-off-by: Josh Dekker <josh@itanimul.li> |

lavc/aarch64: port HEVC SIMD idct NEON
Makes SIMD-optimized 8x8 and 16x16 idcts for 8 and 10 bit depth available on aarch64. For a UHD HDR (10 bit) sample video these were consuming the most time and this optimization reduced overall decode time from 19.4s to 16.4s, approximately 15% speedup. Test sample was the first 300 frames of "LG 4K HDR Demo - New York.ts", running on Apple M1. Signed-off-by: Josh Dekker <josh@itanimul.li> |
