* swscale: Fix AltiVec/VSX build with recent GCCDaniel Kolesa2019-10-04
| | | | | | | | | | | | | The argument to vec_splat_u16 must be a literal. By making the function always inline and marking the arguments const, gcc can turn those into literals, and avoid build errors like: swscale_vsx.c:165:53: error: argument 1 must be a 5-bit signed literal Fixes #7861.

* 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. Fixes #7861. Signed-off-by: Daniel Kolesa <daniel@octaforge.org> Signed-off-by: Lauri Kasanen <cand@gmx.com>

* lsws/ppc/yuv2rgb_altivec: Replace vec_lvsl/vec_perm with vec_xlChip Kerchner2019-08-13
| | | | | | | | | | gcc 6.x and 7.x generate wrong code for little endian machines for the vec_lvsl/vec_perm instruction combos in some cases. The bug was fixed in version 8.x If these instructions are replaced with vec_xl, the problem goes away for all versions of the compilers. Fixes ticket #7124.

* libswcale: Fix possible string overflow in test.Adam Richter2019-05-13
| | | | | | | | | | | In libswcale/tests/swcale.c, the function fileTest() calls sscanf in an argument of "%12s" on character srcStr[] and dstStr[], which are only 12 bytes. So, if the input string is 12 characters, a terminating null byte can be written past the end of these arrays. This bug was found by cppcheck.

* swscale: Add test for isSemiPlanarYUV to pixdesc_queryPhilip Langdale2019-05-12
| | | | | | Lauri had asked me what the semi planar formats were and that reminded me that we could add it to pixdesc_query so we know exactly what the list is.
* swscale: Add support for NV24 and NV42Philip Langdale2019-05-12
| | | | | | | | | | | The implementation is pretty straight-forward. Most of the existing NV12 codepaths work regardless of subsampling and are re-used as is. Where necessary I wrote the slightly different NV24 versions. Finally, the one thing that confused me for a long time was the asm specific x86 path that did an explicit exclusion check for NV12. I replaced that with a semi-planar check and also updated the equivalent PPC code, which Lauri kindly checked.

On x86, SSE2 is ~7. Curiously, the Power C version takes as many cycles as the x86 SSE2 version, yikes it's fast. Note that this function uses VSX instructions, but is not marked so. This is because several existing functions also make that mistake. I'll submit a patch moving them once this is reviewed.
