OK, I think I've sorted this out so will post my findings here in case
it helps anyone else.
My mistake was not understanding what's going on in the default
convert.conf file. All I did was add the #FT line to my custom file. It
looks as if when you seek during playback, LMS starts a whole new
decoding operation, and expects the conversion rule to cope with
starting at the seek position. Of course the rule in my file didn't have
anything in it to define where to begin, and so the song started again
from the start.
As far as I can tell, there isn't an option in sox to start at a
specific place in the file, so we have to run a flac decode starting at
the seek position and pipe its output through sox to re-encode to flac
and do any other processing required - in my case the EQ for room
correction.
So my custom convert file ended up as:
Code:
--------------------
flc flc * b8:27:eb:e0:f9:75
# FT:{START=--skip=%t}U:{END=--until=%v}
[flac] -dcs $START$ $END$ -- $FILE$ | [sox] -q --multi-threaded
--no-clobber -t wav - -t flac -C 0 - equalizer 54.3 2.831q -19.2 equalizer 71.1
3.982q +9.0 equalizer 75.2 7.677q -5.4 equalizer 89.3 11.271q -5.5 equalizer
148 13.429q -13.3 equalizer 202 5.0q -6.2 equalizer 225 5.0q +6.3
--------------------
The mac address is there so the EQ is only applied to the relevant
player, of course, and the various equalizer settings are for the room
that player is in.
>From the tests I've done so far, the seeking now works properly, and the
room EQ is maintained after a seek.
Until recently: Transporter -> ATC SCM100A, now sold :-(
House move forced change to: piCorePlayer(RPi2/HiFiBerry DIGI2 Pro) ->
Meridian 218 -> Meridian M6
