Re: [Savonet-users] request.dynamic & conservative

[David B. <dav...@gm...>]

Hi!

The length parameter says how much data should be available in
advance. In conservative mode, only the queued data is taken into
account as "available in advance". In non-conservative mode (now
default) the remaining time of the current track (if any) is added to
that amount.

One last thing concerning the queue: the duration of the queued files
is only approximated, and the default duration of 30s will often be
used.

Yes in non-conservative mode. But with 60, since the default duration
is 30, there is a possibility that liquidsoap queues two files to get
60s of available data before starting playing the first one, at which
point it will realize that it's much longer than 30s.

Yes, 10s can be too short when request resolution is complex. I hope
my explanations will allow you to fine tune your settings.
