monitor.

final
void
|
wait(long timeoutMillis, int nanos)
Causes the current thread to wait until it is awakened, typically
by being notified or interrupted, or until a
certain amount of real time has elapsed.

Public methods
getPrivateData
public byte[] getPrivateData ()
Retrieves the private data in the CA_Descriptor associated with a track.
Some CAS systems may need this to initialize the CAS plugin object. This
private data can only be retrieved before a valid MediaCas object
is set on the extractor.
| Returns |
|---|
byte[] |
a byte array containing the private data. A null return value
indicates that the private data is unavailable. An empty array,
on the other hand, indicates that the private data is empty
(zero in length). |
getSession
public MediaCas.Session getSession ()
Retrieves the MediaCas.Session associated with a track. The
session is needed to initialize a descrambler in order to decode the
scrambled track. The session object can only be retrieved after a valid
MediaCas object is set on the extractor.
getSystemId
public int getSystemId ()
Retrieves the system id of the conditional access system.
| Returns |
|---|
int |
CA system id of the CAS used to scramble the track. |
