Please test with an MPlayer Windows binary:
It may never have been tested on Linux, I just tested with MPlayer from 2008
when the relevant code was added and it did not work either on Linux.

This is not very likely.

I am also curious about an answer to this but perhaps no one answered due
to the thread hijacking.

​Every time you provide an output filename, all output settings are reset.
You could do something like this:

$ ffmpeg -i input.mp4 -c copy out1.mp4 -c:v h264 -c:a libvorbis out2.mp4 -c
copy -map 0:v out3.mp4

Each output will have the preceding options applied to them.
