...with Visual Studio Express. Building the ogg-library was a piece of cake, but after converting the project-files for theora, I still get numerous errors, such as: fatal error C1083: Datei (Quelle) kann nicht ge?ffnet werden: "..\..\..\lib\dec\x86_vc\x86state.c": No such file or directory mmxstate.c Probably it's just a problem with path-variables incorrectly set, but I'm no real fan of the Visual C environment and I therefore unfortunately just have rudimentary knowledge with that kit and can't fix it. I'm just trying to build a JNI interface library that will incorporate t...

Hello, Here is my first speedup patch. Like 10-11%. No IDCT yet. Please feel free to comment my code or even better think about improvements. :) I belive my routines are not so bad, maybe one day they will be even more faster. What needs to be optimized is the loop filter fuction. I have no ideas now how to do it. It does not leave much space for parallel stuff, copying memory from lot of

Here is the patch with my changes. Most work went into the decoder. I just changed on the encoder if something was nessesary to build the library. You can find the patch here (quite big).. http://torus.untergrund.net/code/theora_mmx_vc2005.diff Please let me know if the encoder works without problems. I just did a very brief testing of it. The decoder has been tested against the test

...is even a tad better than the vs.net one. There is btw. a difference between VS.net whole program optimization or simple per translation unit optimization, but the performance difference is so small that it's nearly lost in the measurement noise. Moving the mmx intrinsic functions into the mmxstate.c file and declaring them as static inline made a bigger difference (still neglible). Cheers, Nils
