Hello again,
I've learned that i could also start the cutting process on the vdr
server itself, without a frontend. With this i also (and 100%
reproducable) got the segfault of the vdr.
I start without a running vdr:
s01# vdr -u vdr --edit=/video/Die_Marx_Brothers_im_Kaufhaus/2012-10-29.01.48.50.99.rec/
and also with a still running vdr and call the --edit with another instance:
vdr -u vdr -i 1 --edit=/video/Die_Marx_Brothers_im_Kaufhaus/2012-10-29.01.48.50.99.rec/
>From both tries i make backtraces with gdb, both differs only in
thread numbering etc.
So i attach the one with -i 1 instance, along with the vdr logfile
output. Maybe one of you see a clearer picture why this segfaults
happen here.
I attach logfile sequence and backtrace output together.
Regards and TIA
Gerhard
