CmfcDescriptiveVideoServiceFlag

Specify whether to flag this audio track as descriptive video service (DVS) in your HLS parent manifest. When you choose Flag (FLAG), MediaConvert includes the parameter CHARACTERISTICS="public.accessibility.describes-video" in the EXT-X-MEDIA entry for this track. When you keep the default choice, Don't flag (DONT_FLAG), MediaConvert leaves this parameter out. The DVS flag can help with accessibility on Apple devices.
