[vdr] Thread error segfault

["Cristiano Bozzi" <c.bozzi@meta.cpr.it>]

Hi all,

I am working on a client-server architecture based on VDR 1.3.12 xine plugin
0.6.0 and streamdev-0.3.3-pre3-geni

I had some problem switching from free to air channels and other encrypted
channels (I have no cam)

es:
from
RAI2;RAI:11765:v:S13.0E:27500:513:651=ita:577:0:3402:318:5200:0
to
Ch. 264 - HB11-12,
HB15-16:12825:v:S19.2E:27500:4260:4322,4332:0:0:264:1:101:0

I think this could be a thread problem.
In my syslog I can see that not all the thread started are closed when I
switch from channels:

Who does have to end the thread:
"receiver on device 6 thread started (pid=13885, tid=163848)" and
"Streamdev: UDP-TS Assembler thread started (pid=13886, tid=180233)"

Following I attach my coredump; it seems to be a thread creation problem

#0  0x40051300 in sem_timedwait () from /lib/libpthread.so.0
#1  0x4004dbea in pthread_mutex_unlock () from /lib/libpthread.so.0

#4  0x4004ccc4 in pthread_detach () from /lib/libpthread.so.0
#5  0x40259037 in clone () from /lib/libc.so.6

at the end the errno value is 11 (EAGAIN)

does anyone have some suggestions?

thanks
