1// Shape-compatible stubs used by docs.rs builds (DOCS_RS=1).
2//
3// These definitions mirror the real bindgen-generated FFmpeg bindings in type
4// and name, but contain no actual FFmpeg code.  All functions are no-op stubs
5// that never run; they exist only to make the dependent crates compile so that
6// rustdoc can render their public APIs.
7//
8// Maintenance note: add entries here whenever a new ff_sys symbol is referenced
9// in ff-probe, ff-decode, or ff-encode.  The values of integer constants are
10// taken from the FFmpeg 7.x headers for reference accuracy, but correctness at
11// runtime is irrelevant — docs.rs never executes this code.
