Constructor Detail

Unseekable

public Unseekable(long durationUs)

Parameters:

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

Method Detail

isSeekable

public boolean isSeekable()

Description copied from interface: SeekMap

Returns whether seeking is supported.

If seeking is not supported then the only valid seek position is the start of the file, and so SeekMap.getPosition(long) will return 0 for all input values.

Specified by:

isSeekable in interface SeekMap

Returns:

Whether seeking is supported.

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.

getPosition

public long getPosition(long timeUs)

Description copied from interface: SeekMap

Maps a seek position in microseconds to a corresponding position (byte offset) in the stream from which data can be provided to the extractor.

Specified by:

getPosition in interface SeekMap

Parameters:

timeUs - A seek position in microseconds.

Returns:

The corresponding position (byte offset) in the stream from which data can be provided to the extractor, or 0 if #isSeekable() returns false.
