calculateRenderSize static method

Size calculateRenderSize(
  1. BuildContext context, {
  2. required Size videoSize,
  3. required bool isFullScreenMode,
})

计算视频的实际渲染尺寸和宽高比

Calculate the actual rendering size and aspect ratio of the video.

Implementation

static Size calculateRenderSize(
  BuildContext context, {
  required Size videoSize,
  required bool isFullScreenMode,
}) {
  // 获取当前方向和屏幕尺寸
  final screenSize = MediaQuery.of(context).size;
  // logi("calculateRenderSize: screenSize: $screenSize, videoSize: $videoSize");

  // 如果视频尺寸为空或非法，则根据屏幕方向分配默认尺寸
  if (videoSize == Size.zero ||
      videoSize.width <= 0 ||
      videoSize.height <= 0 ||
      videoSize.aspectRatio <= 0) {
    return screenSize;
  }

  // 竖屏视频（portrait video）
  // TODO: 竖屏视频在全屏与非全屏模式下可能需要不同的布局策略，待后续需求明确后区分
  if (videoSize.height > videoSize.width) {
    return _calculatePortraitDimensions(screenSize, videoSize);
  }

  // 横屏视频（landscape video）
  final aspectRatio = videoSize.aspectRatio;
  return isFullScreenMode
      ? _calculateLandscapeFullScreenDimensions(screenSize, aspectRatio)
      : _calculateLandscapeNonFullScreenDimensions(screenSize, aspectRatio);
}
