(It will probably work with -threads 1, but the 
interesting question is why it fails.)

(I have not seen something similar yet.)
Does this only happen for smk-ebay.avi or 
for every input file?
Is something special about your system?
No memory? No pthreads? Hundreds of CPUs 
(although that shouldn't be a problem)?
