Recording engine (detailed)

Referenced In

Field	Type	Description	Default
name	string	Required. Recording engine. `browser` records the Chrome viewport (concurrency-safe); `ffmpeg` records the screen and supports any application. Accepted values: `browser`, `ffmpeg`	—
target	string	Optional. What the `ffmpeg` engine captures. `display` records the full screen, `window` the active window, `viewport` the browser content area. Ignored by the `browser` engine, which always captures its tab. `window` and `viewport` are best-effort (captured full-screen, then cropped). If unset, defaults to `window` when the recording’s `surface` is an app surface and to `display` otherwise. `viewport` doesn’t apply to app surfaces (they have no browser viewport). Accepted values: `display`, `window`, `viewport`	—
fps	integer	Optional. Capture frame rate for the `ffmpeg` engine. Minimum: 1	`30`
