  • 使用设备抓拍能力或者即时抽帧的方式采集图片,若设备是萤石/海康设备,且具有抓图能力集,则可以使用抓拍能力采集图片;若设备不具备抓拍能力(如国标设备等)则可以使用即时抽帧的方式采集图片
  • 获取文件下载/在线播放地址接口

Memo

云抓拍接口注意事项

  • 使用图片抓拍接口前,需要先确认设备是否具备抓图能力集:support_capture=1则设备支持抓拍,若为0则不支持抓拍。可以通过设备序列号查询设备能力集,
  • 设备抓图能力有限,建议两次抓拍间隔在4秒以上

单元测试

  • 使用前把 t/TestYs7.pm 中的 app_key和secret替换成为自己的
  • 使用 make test 命令进行单元测试
