The == condition is a non-POSIX extension to shell.

It's not supported on NetBSD and it's a fatal error within the pkgsrc
framework, even if the condition might be unused.

Fixes #19964

Don't send IOSurface mapped pictures directly but copy them in a intermediate
picture with uswc.

This improve performances of filters since they could read on a GPU mapped
pictures.

Cf. 497efd3d

We can't do that for HEVC (since it may cause iOS crashes) but there was no
report of keyframes issues with H264.

Fixes #19967

Replaced by the faster Copy420_16_P_to_SP function.

Replaced by the faster i420_nv12 filter.

Mainly used by CVPX.

Since memset is used to set back pixels.

P010 is on MSB, and VLC_CODEC_I420_10B/VLC_CODEC_I420_10L are on LSB, so we
need to shift bits by 6 when doing the conversion. VLC_CODEC_I420_10L should be
used instead of VLC_CODEC_I420_10B since it's little endian.

It "worked" only because the conversion was tested while downloading and
uploading, so the download error was canceled by the upload error. This fixes
screenshot colors.

In order to use Uswc when copying packer pictures (RGB/YUYV).

This commit improve the Y plane copy speed from GPU images.

but codec is set.
