Cargo Features

uvc-src has no features set by default.

[dependencies]
uvc-src = { version = "0.2.1", features = ["jpeg"] }
jpeg = mozjpeg-sys

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.
