直播水印开发指南_视频直播(LIVE)-阿里云帮助中心

直播水印功能可以给直播视频添加水印，通过本文档您可以了解如何实现直播水印功能。

应用场景

版权保护：水印是保护版权的一种常用措施，视频直播服务提供了直播水印功能，可以对直播视频添加水印。

广告：在直播过程中，可以通过直播水印功能在视频中打上广告标签，比如优惠活动等信息。

前期准备

使用水印功能，需要准备水印图片。目前视频直播只支持图片水印，如果您有文字水印需求，可以将文字制作成PNG图片形式（水印图片支持JPG、PNG格式）。
水印图片URL地址。目前视频直播只支持URL地址形式访问水印图片，暂不支持直接上传图片，使用直播水印功能时，请确保视频直播服务能够长期有效地访问您的水印图片。

功能配置

使用直播水印功能需要进行功能配置，配置内容分为水印模板和水印规则两部分。

水印模板：配置水印相关信息，包括水印在直播视频中的位置，透明度，水印图片地址等。

水印规则：配置水印应用规则，包含AppName，StreamName，关联水印模板。

配置水印模板

目前可以通过视频直播控制台以及API配置水印模板。

控制台配置水印模板

登录视频直播控制台。
在左侧导航栏选择功能管理>直播水印，进入直播水印页面，选择水印模板页签。
选择待配置的播流域名。

单击添加水印模板，配置水印模板。

您可以在预览区域查看水印效果，通过调整预览画面尺寸、水印尺寸和位置等信息对实际效果进行实时预览。水印模板参数及说明如下表所示。

参数	描述
水印模板名称	水印模板的名称。支持输入中英文、数字、短划线（-）、下划线（_）符号，长度不超过30个字符。
水印描述	水印信息描述。支持输入中英文、数字、字符，长度不超过128个字符。
水印素材	输入HTTP或HTTPS链接的水印图片地址。建议水印图片地址是OSS的HTTP永久有效地址或者长期鉴权的有效地址。
坐标原点	水印在输出视频画面的大概位置，用于标示水印初始位置，水印将根据此坐标原点进行偏移。取值：右上（默认值）右下左上左下
预览画面尺寸（宽x高）	可以根据实际视频信息输入，预览对应的展示位置和效果。单位：像素。
水印尺寸（宽x高）	水印图片的大小，宽度将根据高度自适应。取值范围：[0，4096]。单位：像素。
水印水平偏移	水印在输出视频画面上水平偏移距离。取值范围：[0，4096]。单位：像素。
水印垂直偏移	水印在输出视频画面上垂直偏移距离。取值范围：[0，4096]。单位：像素。
透明度	水印图片的透明度，值越小越透明，100%代表不透明。取值范围：[0，100]。单位：百分比。

单击保存，完成水印模板配置。
添加水印模板成功后，会弹出添加水印规则提示框。您可以单击立即添加，为此模板添加水印规则；如果您暂不需要添加水印规则，可以选择稍后再说，后续添加。水印规则配置，请参见配置水印规则。
说明
水印模板配置完成后，需要再添加水印规则，并在水印规则中关联水印模板，设置AppName、StreamName，且必须与直播推流地址的AppName、StreamName保持一致，重新推流后，播流中才能带水印。

API配置水印模板

使用API配置水印模板时，建议您结合控制台进行配置（水印模板参数设置较为复杂，控制台配置水印模板可以使用可视化界面拖动以及预览水印位置）。

首先，您通过视频直播控制台添加一个水印模板。

完成各项参数配置后，查询水印模板信息。

说明

各参数说明AddLiveStreamWatermark - 添加⽔印模板API。

到此即完成水印模板配置，配置水印模板之后需要配置水印应用规则。

重要

直播水印暂不支持与直播时移同时配置使用。

配置水印规则

在配置水印模板之后，需要进行水印规则配置。水印规则可以关联水印模板。

水印规则同样可以通过视频直播控制台以及API方式进行配置。

控制台配置水印规则

登录视频直播控制台。
在左侧导航栏选择功能管理>直播水印，进入直播水印页面，选择水印规则页签。
选择待配置的播流域名。

单击添加水印规则。

水印规则参数及说明如下表所示：

参数	描述
规则名称	水印规则名称。支持输入中英文、数字、字符，长度不超过32个字符。
规则描述	水印规则描述。支持输入中英文、数字、字符，长度不超过128个字符。
AppName	播流所属应用名称。AppName必须与推流地址中的AppName名称一样，水印模板才能生效。支持数字、大小写字母、短划线（-）、下划线（_），长度不超过256个字符。
StreamName	直播流名称。规则如下：直接写流名称则仅匹配该流名称。示例：`liveStreamA`。可进行模糊匹配。如果需要匹配全部直播流，仅输入星号（）即可。也可以进行前匹配或后匹配。格式要求：匹配项需要用`()`符号包围，多个匹配项用竖线`\|`分隔；模糊匹配的星号（）只能放在最前面或最后面。示例：`(abc\|123)`表示匹配所有前缀为abc或者123的流；`(t1\|t2)`表示匹配所有后缀为t1或t2的流。支持数字、大小写字母、短划线（-）、下划线（_）、星号（*）、等号（=），长度不超过256个字符。
水印模板	选择已配置好的水印模板。若无模板，请先添加水印模板，具体操作请参见配置水印模板。

单击保存，完成水印规则的配置。
说明
水印规则配置成功后，需要重新推流后，播流中才能带水印。

}

说明

<AppName>不超过256字符，支持数字、大小写字母、短划线（-）、下划线（_），暂不支持星号（*）。
水印规则配置匹配时存在优先级，优先匹配<StreamName>不为星号（*）的配置。
更多参数说明可参见添加水印规则API。

功能使用

水印模板以及水印规则配置完成之后，推流播放即可使用直播水印功能，配置了水印功能的直播视频样例如下图所示：

在该示例中，将文字制作成PNG格式图片实现了水印功能。

水印透明度设置

设置水印透明度示例代码：

Java

//水印透明度，数值越小越透明。取值：0~255。默认255
addLiveStreamWatermarkRequest.setTransparency(255);

比如现在将透明度设置为128，直播视频样例效果如下图所示：

更新水印规则时可以更新规则其他信息，详情可参见APIUpdateLiveStreamWatermarkRule - 更新水印规则。

更新水印模板或水印规则之后需要重新推流才能生效，但有时候您可能需要在直播过程中更新水印，此时可以通过动态更新水印功能实现。

您可以调用动态更新水印API实现动态调整水印功能。

重要

<TemplateId>可以是新建的模板ID，也可以是原模板ID。调用此方法后，将按照模板最新的配置（包括图片，透明度，位置等信息）更新水印。
目前无法动态更新StreamName配置为模糊匹配的水印规则。
