Varying MediaSequence between variant playlist
What do you want to do with Hls.js?
We are doing some Server Side Ad Insertion and sruggling to make it work correctly.
From what we understood from the specs:
A client MUST NOT assume that segments with the same Media Sequence Number in different Variant Streams or Renditions have the same position in the presentation; Playlists MAY have independent Media Sequence Numbers. Instead, a client MUST use the relative position of each segment on the Playlist timeline and its Discontinuity Sequence Number to locate corresponding segments.
In our implementation the Media Sequence greatly varies and is initialized to 1 the first time a variant is requested. It seems however that the client (hls.js) fails to move from playlist to another when the MS differs. But the specs indicate that a client MUST NOT assume media sequence number is the same. It must be noted that we don't currently implement the EXT-X-DISCONTINUITY-SEQ is that mandatroy ? (although it was not present in older specifications)
