As specified in HLS spec (https://tools.ietf.org/html/rfc8216): All audio EXT-X-MEDIA tags SHOULD have a CHANNELS attribute. If a Master Playlist contains two Renditions encoded with the same codec but a different number of channels, then the CHANNELS attribute is REQUIRED; otherwise, it is OPTIONAL. Fixes #299 Change-Id: Ic2308c39b170178b11cb0d94c3a8083c8b5f3353 |
