I've read through, but haven't yet understood the change. I'll need more time. Also, JFYI, Monday is a holiday for Google in the US. |

@joeyparrish What this change does is that LL-HLS byterange is processed in the same way that it is done in LL-DASH. With this we achieve more efficiency according to the Akamai paper and what has been tested by me. |

There was a problem hiding this comment.
Say, it occurs to me. This assumes that a manifest that isn't HLS is DASH, based on the comment above.
But we now have the constant of shaka.media.ManifestParser.MSS. Is this behavior supported by MSS?

Yes, this would work for MSS live (in the future)
