[vlc-devel] [PATCH 1/2] video_filter/blendbench: Create: add missing error-check

[Filip Roséen]

As blendbench.c:Filter relies on the p_sys->p_blend_image to refer to
a valid picture_t, we need to make sure that the relevant call is
successful in blendbench.c:Create (as we otherwise would have a
null-pointer dereference further down the road).
