Well the last thing that is required for icl compatibility now is the
libmpcodec patch. The first 3 have been applied in mplayer upstream but
havnt been synced to ffmpeg yet. The last remaining patch is attached. This
patch adds the named constraints to libmpcodec inline asm which is required
for icl (as done previously in ffmpeg) and is potentially also useful for
lto as per previous discussion on using named constraints with link time
Is there someone here who can look over it and apply it upstream or do I
need to submit it directly to mplayer?
With this last patch (and the upstream sync) ffmpeg will finally have
complete icl asm support.
