This needs {{{-vcodec libvpx}}}.
Please understand that this is not a support forum, and that separating
the console output from the command only makes reading tickets much more
difficult.
I opened ticket #5793 for the issue with the movie filter, work-around is
to compile with {{{--disable-decoder=vp8,vp9}}}.
