Attributes

url

The URL of the media file to be played.

Note:

If you open a common media resource, pass in the value to url. If you open a custom media resource, pass in the value to provider. Agora recommends that you do not pass in values to both parameters in one call; otherwise, this call may fail.

uri

The URI (Uniform Resource Identifier) of the media file.

startPos

The starting position (ms) for playback. The default value is 0.

autoPlay

Whether to enable autoplay once the media file is opened:

true: (Default) Yes.
false: No.

Note:

If autoplay is disabled, you need to call the Play method to play a media file after it is opened.

enableCache

Whether to cache the media file when it is being played:

true:Enables caching.
false: (Default) Disables caching.

Note:

Agora only supports caching on-demand audio and video streams that are not transmitted in HLS protocol.
If you need to enable caching, pass in a value to uri; otherwise, caching is based on the url of the media file.
If you enable this function, the Media Player caches part of the media file being played on your local device, and you can play the cached media file without internet connection. The statistics about the media file being cached are updated every second after the media file is played. See CacheStatistics.

enableMultiAudioTrack

Whether to allow the selection of different audio tracks when playing this media file:

true: Allow to select different audio tracks.
false: (Default) Do not allow to select different audio tracks.

If you need to set different audio tracks for local playback and publishing to the channel, you need to set this parameter to true, and then call the SelectMultiAudioTrack method to select the audio track.

isAgoraSource

Whether the media resource to be opened is a live stream or on-demand video distributed through Media Broadcast service:

true: The media resource to be played is a live or on-demand video distributed through Media Broadcast service.
false: (Default) The media resource is not a live stream or on-demand video distributed through Media Broadcast service.

Note:

If you need to open a live stream or on-demand video distributed through Broadcast Streaming service, pass in the URL of the media resource to url, and set isAgoraSource as true; otherwise, you don't need to set the isAgoraSource parameter.

isLiveSource

Whether the media resource to be opened is a live stream:

true: The media resource is a live stream.
false: (Default) The media resource is not a live stream.

If the media resource you want to open is a live stream, Agora recommends that you set this parameter as true so that the live stream can be loaded more quickly.

Note:

If the media resource you open is not a live stream, but you set isLiveSource as true, the media resource is not to be loaded more quickly.

provider

The callback for custom media resource files. See IMediaPlayerCustomDataProvider.

Note:

If you open a custom media resource, pass in the value to provider. If you open a common media resource, pass in the value to url. Agora recommends that you do not pass in values to both url and provider in one call; otherwise, this call may fail.
