case AVMEDIA_TYPE_AUDIO:
Adds handling of dvcC/dvvC block addition mappings. The parsing creates AVDOVIDecoderConfigurationRecord side data. The configuration block is written when muxing into Matroska, if DOVI side data is present for the track. In version 2.2 of the Dolby ISOM specification, there is also dvwC but it is not in the Matroska spec. Most of the Matroska element parsing was implemented by Plex developers.
