Andreas Rheinhardt	0228e27ded	checkasm/motion: Don't allocate AVCodecContext Instead use one on the stack to avoid pulling in all of libavcodec. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	1 year ago
Martin Storsjö	d69d12a5b9	checkasm: motion: Test different h parameters Previously, the checkasm test always passed h=8, so no other cases were tested. Out of the me_cmp functions, in practice, some functions are hardcoded to always assume a 8x8 block (ignoring the h parameter), while others do use the parameter. For those with hardcoded height, both the reference C function and the assembly implementations ignore the parameter similarly. The documentation for the functions indicate that heights between w/2 and 2*w, within the range of 4 to 16, should be supported. This patch just tests random heights in that range, without knowing what width the current function actually uses. Signed-off-by: Martin Storsjö <martin@martin.st>	3 years ago
Martin Storsjö	237730f0e0	checkasm: motion: Make the benchmarks more stable Don't use the last random offset, but a static one. Signed-off-by: Martin Storsjö <martin@martin.st>	3 years ago
Martin Storsjö	900424cda9	checkasm: Provide enough alignment in the new motion test This fixes the checkasm test in some setups on x86. Signed-off-by: Martin Storsjö <martin@martin.st>	3 years ago
Swinney, Jonathan	c471cc7474	lavc/aarch64: motion estimation functions in neon - ff_pix_abs16_neon - ff_pix_abs16_xy2_neon In direct micro benchmarks of these ff functions verses their C implementations, these functions performed as follows on AWS Graviton 3. ff_pix_abs16_neon: pix_abs_0_0_c: 141.1 pix_abs_0_0_neon: 19.6 ff_pix_abs16_xy2_neon: pix_abs_0_3_c: 269.1 pix_abs_0_3_neon: 39.3 Tested with: ./tests/checkasm/checkasm --test=motion --bench --disable-linux-perf Signed-off-by: Jonathan Swinney <jswinney@amazon.com> Signed-off-by: Martin Storsjö <martin@martin.st>	3 years ago
