In order to support extra data during secure playback, video core meta data buffers need to be allocated from MFC heap. This is required as both HLOS and video core have read-write access to this heap. As each meta buffer size is 8KB and there can be 32 meta & output buffers, increase the MFC ION heap size by 256KB.
