[FFmpeg-devel] [PATCH 1/3] avfilter/vf_ssim360: Use correct type in sizeof

[Anton Khirnov]

Quoting Andreas Rheinhardt (2023-03-12 22:52:49)
> SSIM360Context.ssim360_hist is an array of four pointers to double;
> so sizeof(*ssim360_hist[0]) (=sizeof(double)) is the correct size
> to use to calculate the amount of memory to allocate, not
> sizeof(*ssim360_hist) (which is sizeof(double*)).
> 
> Use FF_ALLOCZ_TYPED_ARRAY to avoid this issue altogether.
> 
> Fixes Coverity issue #1520671.
