Method Detail

isSeekable

public boolean isSeekable()

Description copied from interface: SeekMap

Returns whether seeking is supported. Specified by:isSeekable in interface SeekMapReturns:Whether seeking is supported.

getSeekPoints

public[SeekMap.SeekPoints](SeekMap.SeekPoints.html "class in com.google.android.exoplayer2.extractor")getSeekPoints(long timeUs)

Description copied from interface: SeekMap

Obtains seek points for the specified seek time in microseconds. The returned SeekMap.SeekPoints will contain one or two distinct seek points.

Two seek points [A, B] are returned in the case that seeking can only be performed to discrete points in time, there does not exist a seek point at exactly the requested time, and there exist seek points on both sides of it. In this case A and B are the closest seek points before and after the requested time. A single seek point is returned in all other cases.

Specified by:getSeekPoints in interface SeekMapParameters:timeUs - A seek time in microseconds.Returns:The corresponding seek points.

getDurationUs

public long getDurationUs()

Description copied from interface: SeekMap

Returns the duration of the stream in microseconds. Specified by:getDurationUs in interface SeekMapReturns:The duration of the stream in microseconds, or C.TIME_UNSET if the duration is unknown.

timeUsToTargetTime

public long timeUsToTargetTime(long timeUs)
