A ! between mux. and the audio/x-raw capsfilter makes no sense,
since ... ! mux. represents the destination of a link already (the muxer
in this case).


Looking at the pipeline:

uridecodebin already plugs a demuxer, so you don't need a demuxer after
it. Also, the demuxer for an .mp4 file would be qtdemux.

The bit you're missing is the second audio link from uridecodebin. Your
pipeline should probably look something like this:

  gst-launch-1.0 uridecodebin uri=$uri name=d \
\
  d. ! videoconvert ! timeoverlay ! x264enc ! ... ! mux. \
\
  d. ! audioconvert ! audioresample !
"audio/x-raw,format=S16LE,rate=44100,channels=2" ! voaacenc
bitrate=128000 ! mux. \
\
  flvmux name=mux streamable=true ! rtmpsink location=...


(completely untested of course). You might also want a videorate before
x264enc and an audiorate in front of voaacenc.
