Field Detail

UNSEEKABLE

static final SeekMap UNSEEKABLE

A SeekMap that does not support seeking.

Method Detail

isSeekable

boolean isSeekable()

Whether or not the seeking is supported.

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

Returns:

True if seeking is supported. False otherwise.

getPosition

long getPosition(long timeUs)

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

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.
