The raw audio/video caps have changed quite a bit from 0.10 to 1.0, you
need to adjust more than just change video/x-raw-* to video/x-raw.
Generally a lot of these fields like depth/bpp/masks is now expressed as
part of a format string field. Same for audio, instead of
signed/width/depth/endianness there's a single format field now.

Try:

 video/x-raw,format=RGB,width=320,height=240

and

 audio/x-raw,format=S16BE,channels=2,rate=44100

(are you sure you want BE and not LE?)

Cheers
