Comment (by slhck):

 My thinking was that the libvmaf maintainer would check these bug reports.
 The crash only occurs when using VMAF in ffmpeg. I don't get any segfault
 on the same sequences after converting them to YUV and running VMAF
 directly:

 {{{
 ffmpeg -i test-in.mp4  -c:v rawvideo -pix_fmt yuv420p in.yuv
 ffmpeg -i test-out.mp4  -c:v rawvideo -pix_fmt yuv420p out.yuv
 cd ~/Documents/Software/vmaf
 ./run_psnr yuv420p 1920 1080 ~/Downloads/in.yuv ~/Downloads/out.yuv
 ...
 Aggregate (mean): PSNR_score:46.498158
 }}}
