You might be able to do something like

  souphttpsrc ! audioparse format=raw raw-format=s16le rate=44100
channels=2 ! ...

and

  souphttpsrc ! videoparse format=rgb width=X height=Y
framerate=N/1 ! ...

assuming the audio and video are served separately and the data served
is always frame aligned and video strides match.

Alternatively, you could put the raw PCM/RGB into matroska and serve
that.
