clipbin-obs starts the pinned libobs on a dedicated thread, opens exactly the bundled plugin allowlist, and records official capture sources through one hardware encoder into keyframe-aligned Matroska segments. Status reaches Recording only once the source has a picture and the segment grows on disk. clipbin-probe lists and verifies hardware encoders and records from a real capture source, printing status, health and segment events for validation.

//! Makes development builds run against the OBS runtime in target/obs-runtime.
|
|
//!
|
|
//! OBS starts `obs-ffmpeg-mux` from the running executable's directory, and on
|
|
//! Windows the OBS DLLs must sit beside the executable too, so they are linked
|
|
//! (Unix) or copied (Windows) into the Cargo profile directory. A symlink keeps
|
|
//! the helper's `$ORIGIN/../lib` runpath pointing into the runtime. Packaged
|
|
//! builds place the executable in the runtime's own bin directory instead (see
|
|
//! clipbin_obs::RuntimeLayout).
