Video display, frame rate 640x480 @ 30fps achievable?

[Guenter]

Hi,

I need to develop an application that displays video 640x480 16-bit per
pixel with 30 fps.

I would prefer to do that with Python (wxPython) but don't have any
experience whether it is possible to achieve that frame rate and still
have some resources for other processing left? My development PC would
be a Celeron 1 GHz. The final system could be a faster system.

I would appreciate if anybody could share some experience in that
field.

Thanks for any help.
