No idea what the problem is, is it a compile error? can you point to the lines/functions?
I assume we are talking about common/quic.c?

what prevents you from rendering to a buffer and then giving that to java like
you already do with the jpeg images? I confess not looking at the androidSpice code,
so I'm not sure how exactly you do it, but the two options that come to mind are
passing the jpeg buffer as is and letting java uncompress and display, or uncompressing
and then passing the uncompressed buffer to java. If the later, then just let the
existing rendering code do it's work on a memory buffer and then pass the results.

ok, so exactly what I outline above? but I'm not familiar with JNI or the android
SDK.

sorry, no idea.
