How can I track this errors for good bug-report to ffmpeg developpers ? It's seems need to use the gdb.
Is it right way ?

Q: How do I run xine in gdb? 
A: First make sure you have a debug build. You can either run xine from gdb or attach to an already-running process:
Running xine from gdb:
$ gdb xine
(gdb) handle SIG32 noprint nostop
(gdb) run 
Attaching to a running xine process:
$ gdb xine `pidof xine`
