As written on irc: On both Intel and ppc, I see worse performance for threads=2 and threads =6 than threads=1 with this patch (with heavily increased cpu load). For threads=4, I see a speedup of around 10% at more than twice the cpu load compared with threads=1. Above test was done with only the lavc patch applied. If I also use the lavf patch, the speedup for threads=4 is not reproducible anymore. Even the (assumed to be slow) powerpc cpu allows 17x realtime decoding with current FFmpeg, I am not sure this task is worth the trouble.
