I've been working on the recordserver to see if I can improve the
timings of the recording. If you want to try out this version you can
get it from svn with the export command, i.e.:
svn export
svn://svn.freevo.org/freevo/branches/rel-1/freevo/src/helpers/recordserver.py
and you will need freevo_config.py from
svn://svn.freevo.org/freevo/branches/rel-1/freevo/freevo_config.py
You will need to change the RECORDSERVER_ATTIMER = 0 in your
local_conf.py to start the recordings at the top of the minute.
Attached is a log of four consecutive without any gaps and including a
small overlay of two programs.
Actually there is an odd delay after a kaa.rpc time-out error, I'm not
sure if this has been caused by this error.
