getMeta

public DemuxerTrackMeta getMeta()

Specified by:

getMeta in interface DemuxerTrack

gotoFrame

public boolean gotoFrame(long frameNo)

Description copied from interface: SeekableDemuxerTrack

Goes to exactly frameNo.

Specified by:

gotoFrame in interface SeekableDemuxerTrack

Parameters:

frameNo - Frame number, zero based, to go to.

Returns:

Weather or not the operation was successful. Will fail if the frameNo is out of range.

Specified by:

gotoSyncFrame in interface SeekableDemuxerTrack

Parameters:

frameNo - Frame number, zero based, related to which a sync frame will be selected.

Returns:

If the operation was successful.

getCurFrame

public long getCurFrame()

Description copied from interface: SeekableDemuxerTrack

Gets an index of the frame that the next call to 'nextFrame' will return, zero based.

Specified by:

getCurFrame in interface SeekableDemuxerTrack

Returns:

An index of the next frame, zero based.

seek

public void seek(double second)

Description copied from interface: SeekableDemuxerTrack

Seeks this container to the second provided so that the next call to nextFrame will return a frame at that second.

Specified by:

seek in interface SeekableDemuxerTrack

Parameters:

second - A second to seek to.
