MediaDataSource

Field	Type	Description	中文
`type`	`string`	Indicates media type, `'flv'` or `'mp4'`	类型
`isLive?`	`boolean`	Indicates whether the data source is a live stream	是否直播
`cors?`	`boolean`	Indicates whether to enable CORS for http fetching	跨域
`withCredentials?`	`boolean`	Indicates whether to do http fetching with cookies	是否携带COOKIES
`hasAudio?`	`boolean`	Indicates whether the stream has audio track	开启声音
`hasVideo?`	`boolean`	Indicates whether the stream has video track	开启图像
`duration?`	`number`	Indicates total media duration, in milliseconds	媒体时间总长度，毫秒
`filesize?`	`number`	Indicates total file size of media file, in bytes	文件大小
`url?`	`string`	Indicates media URL, can be starts with `'https(s)'` or `'ws(s)'` (WebSocket)	媒体网络地址
`segments?`	`Array<MediaSegment>`	Optional field for multipart playback, see MediaSegment	媒体列表

如果segments参数存在，则将播放器列为多源媒体播放。

如果是多源媒体播放，则duration，filesize，url 这三个参数将被忽略。

MediaSegment

Field	Type	Description	中文
`duration`	`number`	Required field, indicates segment duration in milliseconds	媒体时间总长度，毫秒
`filesize?`	`number`	Optional field, indicates segment file size in bytes	文件大小
`url`	`string`	Required field, indicates segment file URL	媒体网络地址

Config

Field	Type	Default	Description	中文
`enableWorker?`	`boolean`	`false`	Enable separated thread for transmuxing (unstable for now)	多线程工作？
`enableStashBuffer?`	`boolean`	`true`	Enable IO stash buffer. Set to false if you need realtime (minimal latency) for live stream playback, but may stalled if there’s network jittering.	启用缓存
`stashInitialSize?`	`number`	`384KB`	Indicates IO stash buffer initial size. Default is `384KB`. Indicate a suitable size can improve video load/seek time.	缓存大小
`isLive?`	`boolean`	`false`	Same to `isLive` in MediaDataSource, ignored if has been set in MediaDataSource structure.	是否直播，会覆盖上面的配置
`lazyLoad?`	`boolean`	`true`	Abort the http connection if there’s enough data for playback.	懒加载，如果缓存到足够的秒数，则停止下载
`lazyLoadMaxDuration?`	`number`	`3 * 60`	Indicates how many seconds of data to be kept for `lazyLoad`.	懒加载最多的秒数
`lazyLoadRecoverDuration?`	`number`	`30`	Indicates the `lazyLoad` recover time boundary in seconds.	缓存剩余秒数时继续下载
`deferLoadAfterSourceOpen?`	`boolean`	`true`	Do load after MediaSource `sourceopen` event triggered. On Chrome, tabs which be opened in background may not trigger `sourceopen` event until switched to that tab.
`autoCleanupSourceBuffer`	`boolean`	`false`	Do auto cleanup for SourceBuffer	自动清理缓存
`autoCleanupMaxBackwardDuration`	`number`	`3 * 60`	When backward buffer duration exceeded this value (in seconds), do auto cleanup for SourceBuffer
`autoCleanupMinBackwardDuration`	`number`	`2 * 60`	Indicates the duration in seconds to reserve for backward buffer when doing auto cleanup.
`fixAudioTimestampGap`	`boolean`	`true`	Fill silent audio frames to avoid a/v unsync when detect large audio timestamp gap.	填补无音频帧
`accurateSeek?`	`boolean`	`false`	Accurate seek to any frame, not limited to video IDR frame, but may a bit slower. Available on `Chrome > 50`, `FireFox` and `Safari`.	精确寻帧到任何帧，不局限于视频IDR帧，但可能会慢一点。可在Chrome >火狐和Safari浏览器。
`seekType?`	`string`	`'range'`	`'range'` use range request to seek, or `'param'` add params into url to indicate request range.
`seekParamStart?`	`string`	`'bstart'`	Indicates seek start parameter name for `seekType = 'param'`
`seekParamEnd?`	`string`	`'bend'`	Indicates seek end parameter name for `seekType = 'param'`
`rangeLoadZeroStart?`	`boolean`	`false`	Send `Range: bytes=0-` for first time load if use Range seek	发送范围:Range: bytes=0- 如果使用范围查找第一次加载
`customSeekHandler?`	`object`	`undefined`	Indicates a custom seek handler	指示自定义查找处理程序
`reuseRedirectedURL?`	`boolean`	`false`	Reuse 301/302 redirected url for subsequence request like seek, reconnect, etc.	重用301/302重定向url，用于随后的请求，如查找、重新连接等。
`referrerPolicy?`	`string`	`no-referrer-when-downgrade`	Indicates the Referrer Policy when using FetchStreamLoader	指示使用FetchStreamLoader时的引用方策略
`headers?`	`object`	`undefined`	Indicates additional headers that will be added to request	添加请求头
