int |
read(ExtractorInput input,
PositionHolder seekPosition)
Extracts data read from a provided
ExtractorInput . |
void |
release()
Releases all kept resources.
|
void |
seek(long position)
Notifies the extractor that a seek has occurred.
|
boolean |
sniff(ExtractorInput input)
Returns whether this extractor can extract samples from the

Extractor
Following a call to this method, the ExtractorInput
passed to the next invocation of
Extractor.read(ExtractorInput, PositionHolder)
is required to provide data starting from position
in the stream. Valid random access positions are the start of the stream and
positions that can be obtained from any SeekMap
passed to the ExtractorOutput
.

A single call to this method will block until some progress has been made, but will not block for longer than this. Hence each call will consume only a small amount of input data.
In the common case, Extractor.RESULT_CONTINUE
is returned to indicate that the
ExtractorInput
passed to the next read is required to provide data continuing from the
position in the stream reached by the returning call. If the extractor requires data to be
provided from a different position, then that position is set in seekPosition
and
Extractor.RESULT_SEEK
is returned. If the extractor reached the end of the data provided by the
ExtractorInput
, then Extractor.RESULT_END_OF_INPUT
is returned.
