Andreas Rheinhardt	8b4f7c0663	avcodec/me_cmp: Zero MECmpContext in ff_me_cmp_init() Not every function will be set, so zero the context to initialize everything. This also allows to remove an initialization in dvenc.c. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	7 months ago
Andreas Rheinhardt	b1a31b32ab	avcodec/me_cmp,dvenc,mpegvideo: Move ildct_cmp to its users MECmpContext.ildct_cmp is an array of function pointers that are not set by ff_me_cmp_init(), but that are set by users to one of the other arrays via ff_set_cmp(). Remove these pointers from MECmpContext and add pointers for the actually used functions to its users. (The DV encoder already did so.)

Andreas Rheinhardt	cd2e46a350	avcodec/me_cmp, mpegvideo: Move frame_skip_cmp to MpegEncContext MECmpContext has several arrays of function pointers that are not set by ff_me_cmp_init(), but that are set by users to one of the other arrays via ff_set_cmp(). One of these other users is mpegvideo_enc; it is the only user of MECmpContext.frame_skip_cmp and it only uses one of these function pointers at all. This commit therefore moves this function pointer to MpegEncContext; and removes the array from MECmpContext. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	7 months ago
Andreas Rheinhardt	182e647a64	avcodec/me_cmp, motion_est: Move me_(pre_)?_cmp etc. to MotionEstContext MECmpContext has several arrays of function pointers that are not set by ff_me_cmp_init(), but that are set by users to one of the other arrays via ff_set_cmp(). One of these other users is the motion estimation API. It uses MECmpContext.(me_pre\|me\|me_sub\|mb)_cmp. It is basically the only user of these arrays. This commit therefore moves these arrays to MotionEstContext; this has the additional advantage of making motion_est.c more independent from MpegEncContext.

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>	2 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
