# Rust bindings for V4L2
|
|
|
|
This is a vendored, One-KVM-specific subset of `v4l2r`.
|
|
|
|
It keeps only the pieces needed for video capture:
|
|
|
|
- generated Linux V4L2 bindings,
|
|
- safe low-level ioctl wrappers used by capture and device probing,
|
|
- memory handle helpers for `MMAP`, `USERPTR`, and `DMABUF`,
|
|
- core V4L2 types such as `Format`, `PixelFormat`, and `QueueType`.
|
|
|
|
The upstream crate also contains high-level device abstractions, stateful
|
|
decoder/encoder helpers, stateless codec controls, examples, and C FFI. Those
|
|
parts are intentionally removed here so this dependency stays scoped to capture.
|
|
|
|
## Build options
|
|
|
|
`cargo build` generates V4L2 bindings from the vendored Linux UAPI headers in
|
|
`include/`.
