* swscale/x86/output: add AVX2 version of yuv2nv12cXNelson Gomez2020-06-14
| | | | | | | | | | 256 bits is just wide enough to fit all the operands needed to vectorize the software implementation, but AVX2 is needed to for a couple of instructions like cross-lane permutation. Output is bit-for-bit identical to C. Signed-off-by: Nelson Gomez <nelson.gomez@microsoft.com>
* swscale: make yuv2interleavedX more asm-friendlyNelson Gomez2020-06-14
| | | | | | | | | Extracting information from SwsContext in assembly is difficult, and rearranging SwsContext just for asm access didn't look good. These functions only need a couple of fields from it anyway, so just make them parameters in their own right. Signed-off-by: Nelson Gomez <nelson.gomez@microsoft.com>

* swscale: arm: fix NEON hscale initJosh de Kock2020-05-15
| | | | | | | | | | | | | | | | | The NEON hscale function only supports X8 filter sizes and should only be selected when these are being used. At the moment filterAlign is set to 8 but in the future when extra NEON assembly for specific sizes is added they will need to have checks here too. The immediate usecase for this change is making the hscale checkasm test easier and without NEON specific edge-cases (x86 already has these guards). This applies the same fix from 718c8f9aa59751bb490e2688acf2b5cb68fd5ad1 on the 32 bit arm version of the function, fixing fate-checkasm-sw_scale there.

* swscale/vscale: Increase type strictnessAndreas Rheinhardt2020-04-27
| | | | | | | | | | | | | | | | | | | | | | | | | libswscale/vscale.c makes extensive use of function pointers and in doing so it converts these function pointers to and from a pointer to void. Yet this is actually against the C standard: C90 only guarantees that one can convert a pointer to any incomplete type or object type to void* and back with the result comparing equal to the original which makes pointers to void generic pointers to incomplete or object type. Yet C90 lacks a generic function pointer type. C99 additionally guarantees that a pointer to a function of one type may be converted to a pointer to a function of another type with the result and the original comparing equal when converting back. This makes any function pointer type a generic function pointer type. Yet even this does not make pointers to void generic function pointers. Both GCC and Clang emit warnings for this when in pedantic mode. This commit fixes this by using a union that can hold one member of any of the required function pointer types to store the function pointer. This works even for C90.

The double free is because the pointer to cascaded_context of an sw_context is not set to NULL after freeing it.

* swscale/aarch64: use multiply accumulate and shift-right narrowSebastian Pop2020-01-04
| | | | | | | | | | | | | | | | | | | This patch rewrites the innermost loop of ff_yuv2planeX_8_neon to avoid zips and horizontal adds by using fused multiply adds. The patch also uses ld1r to load one element and replicate it across all lanes of the vector. The patch also improves the clipping code by removing the shift right instructions and performing the shift with the shift-right narrow instructions. I see 8% difference on an m6g instance with neoverse-n1 CPUs: $ ffmpeg -nostats -f lavfi -i testsrc2=4k:d=2 -vf bench=start,scale=1024x1024,bench=stop -f null - before: t:0.014015 avg:0.014096 max:0.015018 min:0.013971 after: t:0.012985 avg:0.013013 max:0.013996 min:0.012818 Tested with `make check` on aarch64-linux.

* swscale: Replace illegal vector keyword usage in altivec codeDaniel Kolesa2019-10-04
| | | | | | | | | | | | | | | | | | | | | While this technically compiles in current ffmpeg, this is only because ffmpeg is compiled in strict ISO C mode, which disables the builtin 'vector' keyword for AltiVec/VSX. Instead this gets replaced with a macro inside altivec.h, which defines vector to be actually __vector, which accepts random types. Normally, the vector keyword should be used only with plain scalar non-typedef types, such as unsigned int. But we have the vec_(s|u)(8|16|32) macros, which can be used in a portable manner, in util_altivec.h in libavutil. This is also consistent with other AltiVec/VSX code elsewhere in the tree.
