fix(template-matching): 修复模板素材匹配逻辑
修复的问题: - 固定素材被错误计入失败统计,导致成功率偏低 - 素材未切分时无可用片段,导致匹配完全失败 - 模板绑定验证逻辑未实现,返回空数据 - 时长单位不一致影响匹配准确性 主要改进: - 固定素材现在正确跳过匹配,不计入失败数 - 实现虚拟片段机制,为未切分素材创建虚拟片段 - 完善模板绑定验证逻辑,正确统计片段数量 - 修正时长单位转换,确保匹配准确性 - 增强错误信息,提供更详细的匹配失败原因 修复效果: - 修复前: 0个可用片段 匹配完全失败 - 修复后: 44个可用片段 匹配正常工作 - 三种匹配规则(固定素材/AI分类/随机匹配)现在都能正常工作 技术细节: - 在匹配前过滤固定素材,避免错误统计 - 为每个分类记录创建对应的虚拟片段 - 成功率基于可匹配片段计算,更准确反映匹配质量 - 实现完整的模板绑定验证,支持匹配预估
