* lsws/ppc/yuv2rgb: Fix transparency converting from yuv->rgb32.Carl Eugen Hoyos2021-01-24
| | | | | | Based on 68363b69 by Reimar Döffinger. Fixes ticket #9077.
* lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bumpAnton Khirnov2021-01-01
| | | | They are not properly namespaced and not intended for public use.
* lavu: move LOCAL_ALIGNED from internal.h to mem_internal.hAnton Khirnov2021-01-01
| | | | That is a more appropriate place for it.

* swscale/rgb2rgb_template: use shuffle macro on big-endian archesAndriy Gelman2020-12-12
| | | | | | | | | | | | | | Fixes fate-qtrle-32bit on big-endian. The macro does a simple byte swap on uint8 array without any casts, so it's valid on big-endian arches. The mentioned test was failing because the byteswap function shuffle_bytes_3210_c() is used in the pixel format conversion (argb->bgra).

* libswcale/input: use more accurate planer rgb16 yuv conversionsMark Reid2020-10-06
| | | | | | | These conversion appears to be exhibiting the same rounding error as the rgbf32 formats where. I seperated the rounding value from the 16 and 128 offsets, I think it makes it a little more clear. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

| | | | | | | | | | 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: 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 x18 is a reserved platform register on Darwin and Windows. x8/w8 seems to be unused in this function though (and same about x10 and x14), so there's really no reason to use x18 here - just change the uses of x18/w18 into x8/w8 instead without any further rewrites.
