  @Deprecated
  static final DrmSessionManager DUMMY

  Deprecated.

  Use DRM_UNSUPPORTED.
  An instance that supports no DRM schemes.

Method Detail

• getDummyDrmSessionManager

  @Deprecated
  static DrmSessionManager getDummyDrmSessionManager()

  Deprecated.

  Use DRM_UNSUPPORTED.
  Returns DRM_UNSUPPORTED.

• prepare

  default void prepare()

  Acquires any required resources.

  release() must be called to ensure the acquired resources are released. After releasing, an instance may be re-prepared.

• release

  default void release()

  Releases any acquired resources.

• setPlayer

  void setPlayer​(Looper playbackLooper,
                 PlayerId playerId)

  Sets information about the player using this DRM session manager.

  Parameters:

  playbackLooper - The Looper associated with the player's playback thread.

  playerId - The PlayerId of the player.

• preacquireSession

  default DrmSessionManager.DrmSessionReference preacquireSession​(@Nullable
                                                                  DrmSessionEventListener.EventDispatcher eventDispatcher,
                                                                  Format format)

  Pre-acquires a DRM session for the specified Format.

  This notifies the manager that a subsequent call to acquireSession( DrmSessionEventListener.EventDispatcher, Format) with the same Format is likely, allowing a manager that supports pre-acquisition to get the required DrmSession ready in the background.

  The caller must call DrmSessionManager.DrmSessionReference.release() on the returned instance when they no longer require the pre-acquisition (i.e. they know they won't be making a matching call to acquireSession(DrmSessionEventListener.EventDispatcher, Format) in the near future).

  This manager may silently release the underlying session in order to allow another operation to complete. This will result in a subsequent call to acquireSession( DrmSessionEventListener.EventDispatcher, Format) re-initializing a new session, including repeating key loads and other async initialization steps.

  The caller must separately call acquireSession( DrmSessionEventListener.EventDispatcher, Format) in order to obtain a session suitable for playback. The pre-acquired DrmSessionManager.DrmSessionReference and full DrmSession instances are distinct. The caller must release both, and can release the DrmSessionManager.DrmSessionReference before the DrmSession without affecting playback.

  This can be called from any thread.

  Implementations that do not support pre-acquisition always return an empty DrmSessionManager.DrmSessionReference instance.

  Parameters:

  eventDispatcher - The DrmSessionEventListener.EventDispatcher used to distribute events, and passed on to DrmSession.acquire(DrmSessionEventListener.EventDispatcher).

  format - The Format for which to pre-acquire a DrmSession.

  Returns:

  A releaser for the pre-acquired session. Guaranteed to be non-null even if the matching acquireSession(DrmSessionEventListener.EventDispatcher, Format) would return null.

• acquireSession

  @Nullable
  DrmSession acquireSession​(@Nullable
                            DrmSessionEventListener.EventDispatcher eventDispatcher,
                            Format format)

  Returns a DrmSession for the specified Format, with an incremented reference count. May return null if the Format.drmInitData is null and the DRM session manager is not configured to attach a DrmSession to clear content. When the caller no longer needs to use a returned DrmSession, it must call DrmSession.release(DrmSessionEventListener.EventDispatcher) to decrement the reference count.

  If the provided Format contains a null Format.drmInitData, the returned DrmSession (if not null) will be a placeholder session which does not execute key requests, and cannot be used to handle encrypted content. However, a placeholder session may be used to configure secure decoders for playback of clear content periods, which can reduce the cost of transitioning between clear and encrypted content.

  Parameters:

  eventDispatcher - The DrmSessionEventListener.EventDispatcher used to distribute events, and passed on to DrmSession.acquire(DrmSessionEventListener.EventDispatcher).

  format - The Format for which to acquire a DrmSession.

  Returns:

  The DRM session. May be null if the given Format.drmInitData is null.

• getCryptoType

  @com.google.android.exoplayer2.C.CryptoType int getCryptoType​(Format format)

  Returns the C.CryptoType that the DRM session manager will use for a given Format. Returns C.CRYPTO_TYPE_UNSUPPORTED if the manager does not support any of the DRM schemes defined in the Format. Returns C.CRYPTO_TYPE_NONE if Format.drmInitData is null and acquireSession(com.google.android.exoplayer2.drm.DrmSessionEventListener.EventDispatcher, com.google.android.exoplayer2.Format) will return null for the given Format.

  Parameters:

  format - The Format.

  Returns:

  The C.CryptoType that the manager will use, or @link C#CRYPTO_TYPE_UNSUPPORTED} if the manager does not support any of the DRM schemes defined in the Format. Will be C.CRYPTO_TYPE_NONE if Format.drmInitData is null and acquireSession(com.google.android.exoplayer2.drm.DrmSessionEventListener.EventDispatcher, com.google.android.exoplayer2.Format) will return null for the given Format.
