[vlc-devel] [PATCH 09/48] hls: VOD fast start

[Jean-Paul Saman]

I believe this is more a 'personal preference' thing. Since some
people want a fast start others want to start at the highest quality.
It should probably be an option, eg: --httplive-fast-start (true or
false by default).

Fast start or not is independent of the HLS stream being a live or vod
stream. In both cases the RFC (or was it Apple) suggested that at
least 3 segments should be prefetched for stable playback.

Kind regards,

Jean-Paul Saman.
