 /**
  * Video decoder interface.
  *
  * Typical usage:
  * - Use Create() to create & configure a new PPB_VideoDecoder_Dev resource.
  * - Call Decode() to decode some video data.
  * - Receive ProvidePictureBuffers callback
  *   - Supply the decoder with textures using AssignPictureBuffers.
  * - Receive PictureReady callbacks
  *   - Hand the textures back to the decoder using ReusePictureBuffer.
  * - To signal EOS to the decoder: call Flush() and wait for NotifyFlushDone
  *   callback.
  * - To reset the decoder (e.g. to implement Seek): call Reset() and wait for
  *   NotifyResetDone callback.
  * - To tear down the decoder call Destroy().
  *
  * See PPP_VideoDecoder_Dev for the notifications the decoder may send the
  * plugin.
