qsv_stub.rs

1//! Stub Intel QSV encoder, compiled when the `qsv` feature is **off**.
2//!
3//! Keeps `qsv::QsvEncoder` a real type so the dispatcher in
4//! `encode/mod.rs` compiles unchanged, but construction always errors —
5//! auto-select then skips the Intel tier, and an explicit
6//! `EncoderBackend::Qsv` request surfaces the error. Enable `--features
7//! qsv` to compile the real oneVPL-backed encoder (`qsv.rs`).
