问题

GeneratedVideo 查重记录创建失败，报错 float32 is not JSON serializable。

根因

cv2.normalize() 返回 np.float32 数组，color_histograms 直接存进 VideoFingerprint.to_dict() 后，SQLAlchemy JSON 字段序列化时 Python 原生 json.dumps 不支持 numpy 类型。

修复

VideoFingerprint.to_dict() 中统一转 Python 原生类型：

  • color_histograms: np.float32 → float
  • duration: 统一转 float
  • resolution: np.int32 → int

影响范围

  • generate_video 任务：查重记录创建
  • render_edit_plan 任务：查重记录创建
