    API调用视频鉴黄v1(不推荐)

    最近更新时间: 2019-07-11 17:59:09

    视频鉴黄提供视频内容检测,识别视频中是否存在色情内容。

    • 支持存储在七牛云 bucket(支持华东、华北和华南 bucket)或 非七牛云 bucket 中的视频进行视频鉴黄。
    • 支持实时处理和异步处理两种方式:实时处理时,视频鉴黄结果会在识别完成后立即返回;异步处理时,会立即返回job_id,视频鉴黄结果通过job_id获得。
    • 视频鉴黄结果会返回所有视频片段是属于色情、性感、还是正常的识别结果。同时为了让用户知道一个视频整体的分类,返回的结果会包含视频片段中出现过的分类,并显示属于这个分类的视频片段的最高的置信度。
    • 可以通过设置请求参数,仅返回满足客户需求的视频片段(例如:用户仅需要返回色情的视频片段,以便对这部分内容做人工审核)。
    • 支持一次调用同时请求鉴黄、鉴暴恐、敏感人物识别。请查看文档中三鉴(鉴黄、鉴暴恐和敏感人物识别)同时调用的示例。

    视频片段segments视频鉴黄是把视频截帧后,对截帧图片进行鉴黄。当连续帧推理结果一致时,表示这些帧都属于同一种类型,则把这一时段的视频认为是一个视频片段。

    注意: 需要在 POST 请求的 head 部分添加七牛鉴权,以进行用户身份验证。

    参数 类型 必选 说明
    vid string 调用者设置的视频唯一标识,异步处理的返回结果中会带上该信息
    data.uri string 视频地址
    params.async boolean true是异步处理,false是同步处理,不填则取默认值false
    params.vframe.mode int 截帧逻辑,可选值为[0, 1]0表示每隔固定时间截一帧,固定时间在vframe.interval中设定;1表示截关键帧。不填表示取默认值1
    params.vframe.interval int params.vframe.mode0时,用来设置每隔多长时间截一帧,单位s, 取值范围为1~60,不填则取默认值5s
    params.save.bucket string 保存截帧图片的Bucket名称,目前只支持华东的bucket。如何创建七牛云bucket,请参见文档
    params.save.prefix string 截帧图片名称的前缀,图片名称的格式为<prefix>/<video_id>/<offset> (图片命名格式仅供参考,业务请不要依赖此命名格式)
    params.hookURL string 视频检测结束后的回调地址
    ops.op string 视频检测执行的命令,支持多种视频检测操作。目前,视频鉴黄的命令就是pulp
    ops.op.params.labels.label string 对某个命令返回label进行过滤,必须与ops.op.params.labels.selectops.op.params.labels.score一起使用。例如,视频鉴黄的命令pulp的label有0色情, 1性感, 2正常。如果设置为label=0和select=2,则返回结果中只返回label=0的片段。注:score 越高,说明属于这一个分类(label)的概率越高。比如色情、性感、正常的label,正常这个label对应的score最高,则说明图片最有可能是正常的。
    ops.op.params.labels.select int ops.op.params.labels.label中设置的label,设置过滤条件,1表示忽略不选,2表示只选该类别。
    ops.op.params.labels.score float 过滤返回label结果的置信度参数,当ops.op.params.labels.select=1时表示忽略不选小于该设置的结果,当select=2时表示只选大于等于该设置的结果

    价格

    视频鉴黄的工作流程如下:
    1)按照API里面的设置对视频进行截帧,不额外收费
    2)对截帧进行图片鉴黄
    所以,视频鉴黄的价格最终还是图片鉴黄的价格,具体价格请参考

    服务价格

    视频鉴黄是对视频截帧后,对截帧进行图片鉴黄,所以视频鉴黄价格实际使用的是截帧图片鉴黄的价格,与图片鉴黄共用范围。

    例:
    某月视频文件使用视频鉴黄服务,视频截帧的数量为400万,即视频鉴黄产生的图片鉴黄量为400万;当月图片文件使用鉴黄服务,其调用量为106万。则这个月总的图片鉴黄调用量为506万,账单金额则为:
    图片鉴黄:

    3000000*0.155/100+2000000*0.145/100=4650+2900=7550元
