private _tryFixBufferStall(bufferInfo: *, stalledDurationMs: *) source

Detects and attempts to fix known buffer stalling issues.

Params:

NameTypeAttributeDescription
bufferInfo *

The properties of the current buffer.
stalledDurationMs *

The amount of time Hls.js has been stalling for.

private _tryNudgeBuffer() source

Attempts to fix buffer stalls by advancing the mediaElement's current time by a small amount.

private _trySkipBufferHole(partial: *): number source

Attempts to fix buffer stalls by jumping over known gaps caused by partial fragments

Params:

NameTypeAttributeDescription
