Sure, here it is (patch against current svn
Atm, s2api is only used for S/S2.
In order to play H264/HD with kaffeine/xine, you need a fairly recent ffmpeg
and xine compiled with --with-external-ffmpeg configure option. (and of
course a quite strong cpu, unlike my old athlon-xp-2600 :)
However, you can still record and/or broadcast without this update.
