[FFmpeg-devel] [PATCH v2] tests/fate/vcodec: Limit mem alignment for vsynth..mpeg2-422 tests

[softworkz]

From: softworkz <softworkz at hotmail.com>

These tests:

- vsynth2-mpeg2-422
- vsynth1-mpeg2-422
- vsynth_lena-mpeg2-422

were failing on newer CPUs where av_cpu_max_align() returns
values > 32. This patch sets cpuflags to disable avx512
extensions for those tests only.
