Function buildHwScaleFilter

buildHwScaleFilter(
    opts: {
        accel: Hwaccel;
        width: number;
        height: number;
        format?: string;
        mode?: "fast_bilinear" | "bilinear" | "bicubic" | "neighbor" | "area";
    },
): string
Build a GPU-accelerated scale filter.

Throws for accelerations ffmpeg has no GPU scaler for (videotoolbox and the D3D/DXVA/VA-API-on-Windows paths do not ship one) rather than silently emitting a software scale the caller would think is accelerated.
Parameters
- opts: {
      accel: Hwaccel;
      width: number;
      height: number;
      format?: string;
      mode?: "fast_bilinear" | "bilinear" | "bicubic" | "neighbor" | "area";
  }
  - accel: Hwaccel
  - width: number
  - height: number
  - Optionalformat?: string
    Optional format string for VAAPI (e.g. 'nv12|cuda').
  - Optionalmode?: "fast_bilinear" | "bilinear" | "bicubic" | "neighbor" | "area"
Returns string
