 > Please test running the same {{{ffmpeg}}} binary on both systems.
 I had some difficulty to build a binary portable across the 2 machines,
 and had to change the build configuration by adding {{{--disable-hwaccels
 --disable-devices --disable-vdpau}}}.
 Full configure line is now:
 --enable-gpl --enable-version3 --enable-nonfree --disable-runtime-
 cpudetect --disable-ffserver --disable-ffplay --disable-encoders
 --disable-decoders --disable-filters --disable-debug --disable-hwaccels
 --disable-devices --disable-vdpau

 By the way, isn't this a bug that I require both {{{--disable-hwaccels}}}
 and {{{--disable-vdpau}}} to not link against libvdpau?

 I built the binary on the corei7 machine, then rsynced the binary to the
 atom, and...
 $ ffmpeg -loglevel quiet -i cut.mkv -map v -map a -c copy -f md5 -
 ...MD5 is now the same on both machines.

 What is you interpretation of this?
