Ok, I did some more experimenting, sticking to a single codec (Divx5.0).
It seems that the higher I set the framerate, the sooner it segfaults. I
set the framerate down to 5, can I can get a couple minutes of live
encoding done. Also, I noticed that when the system is more heavily
loaded (as in I start up mozilla while encoding), avirec crashes sooner
(usually during the time of high system load). I decided to run it
through a nother gdb session, which I've appended to the end of this
e-mail. Hope it sheds some more light on the problem.
