Fluent API使用(转码端)
目前只介绍已完成的Fluent API,后面还会有例如远程文件转码,添加水印,添加去水印模板,添加跑马灯等API。
特别注意
下面API
使用中所提到的path
参数,支持格式有以下几种:
/path/2.m3u8
./public/videos/3.mp4
public/videos/4.m3u8
https://www.leimulamu.com/videos/202006/12/5ed37e23d6334d5540c43b00/d1052c/index.m3u8
https://www.moemv.com/videos/6.mp4
所用到的apikey
和apisecret
参数均在【转码设置】处设置,且请打开api
。
使用教程
提示:下面所有API不仅可用于服务器上的视频文件,亦可用于任何远程链接形式存在的视频文件。
生成单张截图
post: /apifluent/screenshot
body: {
apikey,
apisecret,
path, // 支持服务器视频文件绝对路径,服务器视频相对路径,服务器源码目录相对路径,远程m3u8连接,远程视频文件链接等。
duration, // 需要截图视频什么时间的画面,单位是秒。
}
response: {
success: 0|1, // 成功或者失败
error, // 如果失败会返回错误信息。
screenshot, // 截图的链接。
}
批量生成截图
post: /apifluent/screenshots
body: {
apikey,
apisecret,
path,
counts //截图数量,会根据视频时间轴,均分截取,比如10秒视频,设置counts为3,则可能截图3,6,9秒的画面。
}
response: {
success: 0|1,
error, //如果有错误信息会返回错误信息。
screenshots, //数组,包含所有截图链接。
}
生成动态图
post: /apifluent/togif
data: {
apikey,
apisecret,
path, //必填,下面的参数选填。
duration, // 生成多少秒动态图,默认1秒
width, //动态图宽度,高度自适应, 默认400宽度
gifstart, // 从视频多少秒开始生成, 默认10秒
auto //是否自动截取视频最中间位置,接收1或0,设置了auto,则gifstart是否设置都无效,默认是0。
}
response: {
success: 0|1,
error,
gif //动态图链接
}
获取视频元信息,即metadata信息
post: /apifluent/metadata
body: {
apikey,
apisecret,
path
}
response: {
success: 1|0,
error,
data // 视频的各种信息,包括音频流,视频流等。
}
data
返回样式样式:

获取试看m3u8格式文本
GET /apifluent/try
headers: {
apikey,
apisecret,
}
query: {
id:视频ID,
duration:试看时长,
hd:指定分辨率,
}
response: m3u8文本 //获取到文本可自行组装自己的m3u8路由。
hd
参数值,320
为240P
、480
为360P
、640
为480P
、1138
为640P
、1280
为720P
、1920
为1080P
、2560
为2K
、20000
为原画。
且hd
和duration
参数可选,默认60
秒试看和最大分辨率,该接口会返回试看m3u8
的文本内容,请自行构建自己的m3u8
路由,勿直接前端使用本接口。
根据视频id和分辨率实时生成mp4
post: /apifluent/savestream
data: {
apikey,
apisecret,
id, //视频库中存在的转码完成的id,
hd //指定生成某分辨率,支持240,360,480,640,720,1080,1440,20000
}
response: {
success: 1|0,
host, // 服务端域名
path, // mp4链接
message // 显示信息
}
此API
可用于提供下载功能时,无需保存mp4
,完全实时根据m3u8
生成mp4
文件,并且返回,秒级反馈。
远程检测转码服务器运行/连接状态
post: /apifluent/ping
data: {
apikey,
apisecret,
}
response: {
success: 1, //1为运行并连接正常,
}
此API
可检测转码程序运行状态,或者和远程转码程序连接情况是否正常。
远程创建转码任务
post: /apifluent/createjob
data: {
apikey,
apisecret,
clientId, //传递一个数据库id,即客户端辨识视频id,返回信息的时候会返回该id,让你对应并进行数据填充。
remotePath, //远程视频地址,即可访问的视频地址
notifyUrl //通知域名,转码完成的clientId、视频名称、m3u8链接、海报截图会自动回传到这个地址。
}
{
"success": 1|0 //1为创建成功
}
此API
可远程创建任务,并调用远程连接转码,建议配合队列转码一起使用,这样创建任务后后,会自动转码,自动返回数据,无需后台操作。

apisecret
}
{
"success": 1|0 //1为删除成功
}
注意id=5fcf24ed3fd3764f5b40f95f
,此id
是EFV
中视频的id
,在远程创建任务,并转码服务完成时会带上efv
中的id
传递到notifyUrl
上,对接的系统接收到此id
储存到自己的数据库中,在删除时就请求delete
删除efv
中的视频数据和切片图片等一切内容。
