These are registered identifiers at the MPEG-4 RA, which are defined as to be utilized for Dolby Vision AVC/HEVC streams that are not correctly presentable by standards-compliant AVC/HEVC players. According to the Dolby Vision specification for ISOBMFF, these sample entry codes are specified to have the standard AVC or HEVC decoder configuration box in addition to the Dolby custom DOVIConfigurationBox. This is what enables us to decode the streams without custom parsing. For correct presentation information from the DOVIConfigurationBox is required (YCbCr or modified ICtCP, SDR or HDR, base or enhancement layer).
