#6691: Segfault when running libvmaf with psnr option
----------------------------------+--------------------------------------

----------------------------------+--------------------------------------
Using latest ffmpeg and latest libvmaf (`d84caaa`) under macOS 10.12. When
running the `libvmaf` filter without options, everything works fine. When
adding `psnr=1` as explained in the docs, I get a segfault.
