...ried many combinations of oggenc options, but the lowest window size, I obtained was still 512. But I want to make file with window size = 256. Is there way to accomplish that? And now, why I need this. I'm working on ogg vorbis decoder optimised for SUN SPARC machines. SUN provides library (medialib, mlib) of multimedia functions, which are written in VIS assembly, so they are fast. I want to optimise bacward MDCT, and use medialib function for it. But here is a problem: medialib IMDCT has hard-coded buffer size = 256. It is not possible to use it for larger buffers (I think - I tried to use i...

The applications now work again, after updating the following packages to version 20120127: app-emulation/emul-linux-x86-baselibs-20110928 app-emulation/emul-linux-x86-xlibs-20110928 app-emulation/emul-linux-x86-medialibs-20110928 app-emulation/emul-linux-x86-soundlibs-20110928 app-emulation/emul-linux-x86-sdl-20110928I think I had tinkered with them before, though, as one of the application's title in the task-bar would state "SDL_app" for the brief moment it ran, but I can't remember exactly whi...

...p, add ARM-NEON simd vectorization using intrinsics. I was able to get over 34% performance improvement on my Beaglebone Black which is single Cortex-A8 based CPU. You can find more information on metrics and procedure I used to measure at https://wiki.linaro.org/WorkingGroups/Middleware/Graphics/MediaLibs/libvorbis As described in above link/doc, you can see my work-in-progress tree at https://git.linaro.org/people/viswanath.puttagunta/vorbis.git Also what standard should one follow when submitting patches to libvorbis? I'm pretty sure linux kernel checkpatch.pl will fail all patches for libv...

Hi, Is there anything special I need to know about VP3's IDCT? I mean besides the fact that there are separate IDCTs to handle sparse coefficient matrices. Are the IDCT functions mathematically equivalent to any textbook IDCT functions?
