Codec type indication for Dolby Digital Plus

For media streams containing Dolby Digital Plus, the CODEC attribute of the EXT-X-STREAM-INF parameter is recommended for codec type indication.

If present, the CODEC attribute must include ec-3 for media presentations using Dolby Digital Plus, as shown in this example:

#EXT-X-STREAM-INF:BANDWIDTH=3464568,CODECS="avc1.640028,ec-3" example.m3u8

An object type indicator (OTI) value must not be appended to the ec-3 string.¹
