用于ruby的Google云视频智能API示例

require "google/cloud/video_intelligence"

# 初始化客户端
video_intelligence_service = Google::Cloud::VideoIntelligence.new

# 视频文件路径
video_path = "path/to/your/video.mp4"

# 配置请求
features = [Google::Cloud::VideoIntelligence::Feature::LABEL_DETECTION]
config = { label_detection_mode: :SHOT_MODE }

# 开始分析
operation = video_intelligence_service.annotate_video(
  input_uri: video_path,
  features: features,
  video_context: { label_detection_config: config }
)

# 等待操作完成
operation.wait_until_done!

# 处理结果
result = operation.result

# 输出标签信息
result.annotation_results.each do |annotation_result|
  annotation_result.segment_label_annotations.each do |label_info|
    puts "Label: #{label_info.entity.description}"
    puts "Confidence: #{label_info.confidence}"
  end
