AQ strength scale is from 1 (low) - 15 (aggressive) (from 1 to 15) (default 8) When Spatial AQ is enabled, this field is used to specify AQ strength. Set 1 to minimize GOP-to-GOP rate fluctuations (default false)
Set this to 1 to enable automatic insertion of non-reference P-frames (default false) Set 1 to indicate zero latency operation (no reordering delay) (default false) set to 1 to enable Temporal AQ (default false) set to 1 to enable Spatial AQ (default false) When lookahead is enabled, set this to 0 to disable adaptive B-frame decision (default true) If forcing keyframes, force them as IDR frames. When lookahead is enabled, set this to 1 to disable adaptive I-frame insertion at scene cuts (default false) Delay frame output by the given amount of frames (from 0 to INT_MAX) (default INT_MAX) (from -2 to INT_MAX) (default any)Īny E.V. Number of concurrent surfaces (from 0 to INT_MAX) (default 32) Number of frames to look ahead for rate-control (from -1 to INT_MAX) (default -1) Multi-pass optimized for constant frame size (only for low-latency presets) Multi-pass optimized for image quality (only for low-latency presets) Override the preset rate-control (from -1 to INT_MAX) (default -1) Set the encoding level restriction (from 0 to 51) (default auto) Set the encoding profile (from 0 to 3) (default main) Set the encoding preset (from 0 to 11) (default medium) Supported pixel formats: yuv420p nv12 p010le yuv444p yuv444p16le bgr0 rgb0
