[features]
# v4l2 and nvjpeg are on by default but their backend code is fully gated
# `#[cfg(all(target_os = "linux", feature = "..."))]`, so off Linux they compile
# to nothing. nvjpeg is pure dlopen (no link-time CUDA dependency) — it loads
# libnvjpeg.so.12 at runtime and degrades to the V4L2/CPU decoders when absent.
