You should give a backtrace. And generally more information.
And I have some doubts this belongs on the dev list instead of some of
the user lists.

Tried overwriting only execute2 and setting it to
Also you should possibly try compiling without pthreads
(if that's what it is using, you didn't even say what system
you run on),
mixing threading implementations was never really intended,
only implementing a threaded execute when FFmpeg was built
without threading support.
