Obviously not, since it works fine on machines with as few as one. Indeed, ffmpeg defaults to using just one unless you pass the "-threads" option. It's debatable whether a single ffmpeg instance could take advantage of that many cores since Amdahl's Law will kick in as it tries to co-ordinate everything. Split it into multiple four- or eight-thread encodes and run them in parallel on that monster server, or even better, run them in parallel on a fleet of much-cheaper desktop machines. _______________________________________________ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer
