You should use multi-threading if you want to decrease overall decoding time, if you need minimal cpu usage, force -threads 1 (multithreading always has an overhead). > (compiling with --enable-w32threads) with Mingw I believe this should not be necessary, if it is there may be a bug (that should be reported).
