Additional information

I am not the OP here but this guy appears to have the same issue: https://forum.mythtv.org/viewtopic.php?f=36&t=4794&p=23541&hilit=mythtranscode#p23541

It sounds like he was able to fix the segfault by assigning a nop for a callback, but had additional issues where the video didn't properly transcode. I searched on mailing list and this issue tracker and found no such mention of this so I figured I'd post it here.
