The command line is in the script file debug/fillborders.sh.
This echo comment line with ./ffmpeg-p1 means that the following runs
were done with the build from patch 1 and with ./ffmpeg-2 from patch 2
for comparison.

You mean this as answer for using the -benchmark option? Thanks for the
hint. But the CPU time for the decoding would still be there, which i'm
afraid, it will too much overflow the little CPU time for the filter.

I did 6 runs for each command line pattern by loop in
debug/fillborders.sh (included in vf_fillbd_benchmark_2.patch).

Ok, I'll try this.
