I rechecked it now and indeed it is vfp compiled so the load drops to ~34% in same Simon scene (see comment #15 above). This is much better but still significantly worse than tremor (eating like 10% in same situation). All this is consistent with findings here

Well, not exactly required but it is better. It doesn't matter much with Simon but e.g. Curse of Monkey Island uses like 80-100% cpu even with tremor so additional overhead of vorbis may make the difference of fluent vs skipping playback. I will recheck this vfp build with COMI.

Sadly I don't remember how exactly I did it but I suppose just checking out from tremor SVN http://svn.xiph.org/trunk/Tremor/ was the trick. Bigger problem was the conflict with FLAC which needs real libogg as described here

Even if I hate having suboptimal scummvm package in the repository maybe it is better than nothing. I guess some explanation in maemo download page (and maybe also directly in package description) mentioning ~20% CPU hit with ogg audio and with pointer to more optimized build for those who really care should be enough.

After all not everyone uses ogg audio compression.

OK, I'll check out build script changes in 0.11.1 source in extras-devel and make 0.12 build.
