Examples of com.lightcrafts.media.jai.codec.SeekableStream.seek()

com.lightcrafts.media.jai.codec.SeekableStream.seek()

Sets the offset, measured from the beginning of this stream, at which the next read occurs.

If canSeekBackwards() returns false, then setting pos to an offset smaller than the current value of getFilePointer() will have no effect. @param pos the offset position, measured in bytes from the beginning of the stream, at which to set the stream pointer. @exception IOException if pos is less than 0 or if an I/O error occurs.
