                           long approxBytesPerFrame)

Constructs a new instance of this seek map.

Method Detail

isSeekable

public boolean isSeekable()

Description copied from interface: SeekMap

Returns whether seeking is supported.

Specified by:

isSeekable in interface SeekMap

Returns:

Whether seeking is supported.

getSeekPoints

public SeekMap.SeekPoints 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 SeekMap

Parameters:

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 SeekMap

Returns:

The duration of the stream in microseconds, or C.TIME_UNSET if the duration is unknown.

timeUsToTargetTime

public long timeUsToTargetTime(long timeUs)
