patch

Clang needs a fix from https://ffmpeg.org/pipermail/ffmpeg-devel/2019-August/247682.html to compile ffmpeg with Altivec. Since VSX is supported only in little-endian variant, we only need a patch for libswscale/ppc/swscale_altivec.c.
Comment 1 Thomas Zander freebsd_committer freebsd_triage 2019-08-23 13:24:20 UTC 
The 2019Q3 branch contains ffmpeg-4.1, the patch does not apply there.
