I guess the bigger issue is where the "execution state" is
maintained. With FFI, Squeak side cannot do too much. You probably
would like to start a few threads outside of Squeak to decode the
video stream, but it would be really cumbersome to control these
threads via FFI. (Imagine to write SocketPlugin without C code
support. or a multi person (n > 2) video conferencing seesion of some
I think it makes more sense to provide semi-platform independent
layer in a plugin, and use it from Squeak.
Yes, Brad, I'd be interested in the multimedia group.
