What happens if you --enable-w32threads? I do not know why Zeranoe
disabled w32threads, but in my builds w32threads are enabled. This might
be the reason why the spikes are not present when I am using my own

Could you try my build of the 20120622 sources? Lots of libs are not
enabled because I do not need them, but libmp3lame, libfaac and libx264
are compiled in:

Of course, I am also interested in the speed of the transcoding, so
please give me feedback on that as well. I was frustrated that my own
MinGW builds were slower than Zeranoe's builds, so I tried MinGW64 on
Windows for a change. Older compiler (4.2.5), but the resulting binaries
were quite up-to-speed.
