Why replace seqNo 0 to 1?

[hori-ryota]

I think #EXT-X-MEDIA-SEQUENCE value is allowed 0 (example: Technical Note TN2288: Example Playlist Files for use with HTTP Live Streaming), but 0 is replaced now. Why?

We had been discussing this today, and don't completely understand why it was introduced in b5ae3cd.

Note, we don't have an issue with this (right now at least) in live or VoD, it's just strange to see.

My project use hls live streaming starting from 0 SeqNo.
We decode our original playlist and processed it with this library.

Now, this library encode like followings at first chunk.

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:5
#EXT-X-MEDIA-SEQUENCE:1
#EXTINF:2.0,
0.ts
#EXTINF:2.0,
1.ts
#EXTINF:2.0,
2.ts

And next,

#EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:5
#EXT-X-MEDIA-SEQUENCE:1
#EXTINF:2.0,
1.ts
#EXTINF:2.0,
2.ts
#EXTINF:2.0,
3.ts

This stream is broken because SeqNo is not changed.
Player cannot playback normally now.

Will you make modifications without a disadvantage?
