Isn't MPI rather unnecessary for video encoding parallelism? It is
rather easy to develop a model (see
http://akuvian.org/src/x264/sliceless_threads.txt) which does not
require communication between threads except to signal the maximum
motion vector search range, which can be done using an atomic write to
a struct variable.
