support for EXT-X-PREFETCH

[joeflateau]

for the competing LHLS proposal, it would be helpful for hls-parser to be able to parse/serialize EXT-X-PREFETCH tags.

@joeflateau Thanks for the link. Let me confirm if I understand you correctly.

• You're trying to implement EXT-X-PREFETCH in hls.js
• hls-parser will be used on the server side to demo/test the EXT-X-PREFETCH implementation in hls.js

Is my understanding correct?

[joeflateau]

Yes, I'm trying to add low latency support for my streams using hls.js player. And I use hls-parser on the server to transform the playlists that ffmpeg creates to fit my needs. Unfortunately right now, that transformation results in the prefetch tags being dropped.

I just reread this and I think I misspoke. I am NOT the one proposing EXT-X-PREFETCH. It's already been proposed and is an open-source low latency HLS proposal that is parallel to apple's proposal. It is already built into the HLS.js player.
