[FFmpeg-devel] [PATCH] Use v4l2 input format automatically if filename starts with "/dev/video"

Andrey quoted these bits of code to show that checking filename for NULL is
not necessary. I believe his proof is conclusive for that point.

Yes, it should. Do you intend to propose the patch that invokes stat() on
all supported operating systems, check that can not devolve into a security
issue in the context of probing, find the relevant list of major/minor
pairs and a way of testing the dynamically allocated ones soon, or are you
just bikeshedding.

Because if you are just bikeshedding, I believe the patch with a lower
score, EXTENSION instead of MAX maybe, would be fine.
