Class M3uStreamSegmentUrlProvider

java.lang.Object

com.sedmelluq.discord.lavaplayer.source.stream.M3uStreamSegmentUrlProvider

Direct Known Subclasses:

BeamSegmentUrlProvider, HlsStreamSegmentUrlProvider, TwitchStreamSegmentUrlProvider

public abstract class M3uStreamSegmentUrlProvider
extends java.lang.Object

Provides track segment URLs for streams which use the M3U segment format. There is a base M3U containing the list of different available streams. Those point to segment M3U urls, which always give the direct stream URLs of last X segments. The segment provider fetches the stream for the next segment on each call to getNextSegmentStream(com.sedmelluq.discord.lavaplayer.tools.io.HttpInterface).
