Method Detail

• setMode

  public void setMode​(@Mode
                      int mode,
                      @Nullable
                      byte[] offlineLicenseKeySetId)

  Sets the mode, which determines the role of sessions acquired from the instance. This must be called before acquireSession(Looper, DrmSessionEventListener.EventDispatcher, Format) is called.

  By default, the mode is MODE_PLAYBACK and a streaming license is requested when required.

  mode must be one of these:

  • MODE_PLAYBACK: If offlineLicenseKeySetId is null then a streaming license is requested. Otherwise, the offline license is restored.
  • MODE_QUERY: offlineLicenseKeySetId cannot be null. The offline license is restored to allow its status to be queried.
  • MODE_DOWNLOAD: If offlineLicenseKeySetId is null then an offline license is requested. Otherwise, the offline license is renewed.
  • MODE_RELEASE: offlineLicenseKeySetId cannot be null. The offline license is released.

  Parameters:

  mode - The mode to be set.

  offlineLicenseKeySetId - The key set id of the license to be used with the given mode.

• prepare

  public final void prepare()

  Description copied from interface: DrmSessionManager
  Acquires any required resources.

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

  Specified by:

  prepare in interface DrmSessionManager

• release

  public final void release()

  Description copied from interface: DrmSessionManager
  Releases any acquired resources.

  Specified by:

  release in interface DrmSessionManager

• preacquireSession

  public DrmSessionManager.DrmSessionReference preacquireSession​(Looper playbackLooper,
                                                                 @Nullable
                                                                 DrmSessionEventListener.EventDispatcher eventDispatcher,
                                                                 Format format)

  Description copied from interface: DrmSessionManager
  Pre-acquires a DRM session for the specified Format.

  This notifies the manager that a subsequent call to DrmSessionManager.acquireSession(Looper, 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 DrmSessionManager.acquireSession(Looper, 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 DrmSessionManager.acquireSession(Looper, DrmSessionEventListener.EventDispatcher, Format) re-initializing a new session, including repeating key loads and other async initialization steps.

  The caller must separately call DrmSessionManager.acquireSession(Looper, 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.

  Specified by:

  preacquireSession in interface DrmSessionManager

  Parameters:

  playbackLooper - The looper associated with the media playback thread.

  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 DrmSessionManager.acquireSession(Looper, DrmSessionEventListener.EventDispatcher, Format) would return null.

• acquireSession

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

  Description copied from interface: DrmSessionManager
  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.

  Specified by:

  acquireSession in interface DrmSessionManager

  Parameters:

  playbackLooper - The looper associated with the media playback thread.

  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

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

  Description copied from interface: DrmSessionManager
  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 DrmSessionManager.acquireSession(android.os.Looper, com.google.android.exoplayer2.drm.DrmSessionEventListener.EventDispatcher, com.google.android.exoplayer2.Format) will return null for the given Format.

  Specified by:

  getCryptoType in interface DrmSessionManager

  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 DrmSessionManager.acquireSession(android.os.Looper, com.google.android.exoplayer2.drm.DrmSessionEventListener.EventDispatcher, com.google.android.exoplayer2.Format) will return null for the given Format.
