Comment (by agressiv):

 I will pipe it from eac3to.  opusenc can take piped input.

 {{{
 eac3to.exe source.mkv stdout.wav | opusenc.exe --bitrate 256k
 --ignorelength - out.opus
 }}}

 {{{
 WARNING: WAV file uses side surround instead of rear for 5.1;
 remapping side speakers to rear in encoding.
 Encoding using libopus 1.1 (audio)
 }}}
