2020-05-20swscale/utils: Fix invalid left shifts of negative numbersAndreas Rheinhardt
Affected the FATE-tests vsynth_lena-dv-411, vsynth1-dv-411, vsynth2-dv-411 and hevc-paramchange-yuv420p.yuv420p10. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc> (cherry picked from commit e2646e23be69bdef1e41d4decee1a4298701b8d1)
2019-05-12swscale: Add support for NV24 and NV42Philip Langdale
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.

2018-03-03swscale: Add p016 output support and generalise yuv420p1x to p010Philip Langdale
To make the best use of existing code, I generalised the wrapper that currently does yuv420p10 to p010 to support any mixture of input and output sizes between 10 and 16 bits. This had the side effect of yielding a working code path for all yuv420p1x formats to p01x.

We already rely on just mmap() in other places.

glibc introduced _DEFAULT_SOURCE in version 2.19 to replace _BSD_SOURCE and _SVID_SOURCE, which were deprecated in version 2.20. Add _DEFAULT_SOURCE where the latter two are used to be forwards-compatible and avoid warnings about the use of deprecated definitions.
