RenderConfig constructor

RenderConfig({ required int width, required int height, required int frameCount, int fps = VideoDefaults.fps, int startFrame = 0, Quality quality = Quality.high, bool cacheEnabled = true, })

Creates a validated render configuration.

Implementation

RenderConfig({
  required this.width,
  required this.height,
  required this.frameCount,
  this.fps = VideoDefaults.fps,
  this.startFrame = 0,
  this.quality = Quality.high,
  this.cacheEnabled = true,
}) {

    throw ArgumentError.value(width, 'width', 'must be positive and even (yuv420p output)');
  }
  if (height <= 0 || height.isOdd) {
    throw ArgumentError.value(height, 'height', 'must be positive and even (yuv420p output)');
  }
  if (fps <= 0) {
    throw ArgumentError.value(fps, 'fps', 'must be positive');
  }

  }
  if (startFrame < 0) {
    throw ArgumentError.value(startFrame, 'startFrame', 'must be >= 0');
