similar to: VC2005 MMX patch.

Hi again, I measured my fragment reconstructions against the compiler output from GCC and well - the new codes perform better, so I brushed up my gcc inline assembler skills and made a port. Code is here: http://torus.untergrund.net/code/mmxfrag.c All routines perform much better now. Inter2 alone got a speedup of factor 5 on Pentium-M. Athlon CPU's execute roughly 3 times faster.

Hi all, Just a heads up to let you know that I've fixed up the Visual C++ project files so that libtheora and the associated experimental programs (dumpvid/encoderwin/splayer/transcoder) builds on Windows again. I also have good news and good news. The bad news is: experimental\splayer doesn't work. It compiles, but segfaults immediately when you try to play any Ogg file. The bug

Hi folks. Mozilla had some issues with the MMX optimized frag_recon functions over the last days, and I was able to track the problem down. The code itself is fine, but it unfortunately it has the tendency to cause a non-deterministic compiler bug. The whole discussion is here: https://bugzilla.mozilla.org/show_bug.cgi?id=474937 After thinking about the problem I've suggested to

Hi, VS2005 project (libspeex.vcproj) seems to be missing some files, most notably filterbank.c. Also some .h files but that doesn't really matter. Gregg

Hi folks, FYI: I've finally made some benchmarks for inline-assembler versus intrinsic based mmx code. I've just applied the changes to the fragment reconstruction functions as writing the IDCT and loopfilter have not been ported yet. Nevertheless here are some numbers: As a baseline I'll take the current version from the trunk with all inline assembler functions enabled. Lower

Forwarding an email exchange that I had with Nils Pipenbrinck regarding the state of the MMX patch for visual studio-style assembly. I also run with the patches, and everything looks fine as far as I can tell. Is this enough for a go-ahead to put that stuff into the mainline (if it's not there already)? -------- Original Message -------- Subject: Re: libtheora MMX patch Date: Sun, 06

While browsing the code I came across line 83 bitpack.c: *_ret=((ret&0xFFFFFFFFUL)>>(m>>1))>>(m+1>>1); Is there any reason why this is so convoluted? Maybe endianess or 64 bit issues? If I'm not mistaken it does exactly the the same as: *_ret = ret >> m; Cheers, Nils

Hi there. I try to cross-compile the theora libraries to test my ARMv6 optimizations (almost done, time to do some benchmarking and testing). While doing so I found out that --with-ogg seems to do nothing. If I simply run: .configure --with-ogg=$HOME The build succeeds also it shouldn't (I don't have ogg installed at $HOME). As an example here is the last line that make executes.

hi, does anzone know of a conformance testsuite e.g. for vorbis and theora bitstreams. This would be nice to have when e.g. testing a dsp based reimplementation. Also a testsuite that does robustness testing on the ogg container format would be nice. If none of these exist, wound't that be a good project for e.g. next GSoC? Stefan

[Robin, sorry if you are receiving this for the third time, have subscribed to the list because previous attempt haven't hit the list] Hello, i took the liberty to port the theorarm-merge-branch to latest svn (used the git mirror actually). The changes already contains the fix Dave Milici posted to the list, plus it adds more fixes: - some warnings about unused variables in

Hopefullly this is once again something trivial I'm missing. I'm still trying to figure out how to pull a part a stream. I get two out the three theora headers I can see in the file (http://v2v.cc/~j/theora_testsuite/320x240.ogg) if I use the buffer in the page struct and nothing usable if I try to use the packet structs. Hopefully this is once again something something trivial I've

A couple of questions: * Do I need a named account to commit changes? How do I get such an account? I'm used to commit roughly once every 8 hours of work if I have a stable point that compiles on linux and win32. That's just my way of working. Worked well in the past to protect myself from doing stupid things. * How anal are you about line endings, tabs vs. spaces, max. line length

Dear R users. I have data observed on the surface of a torus, and am trying to fit the nonlinear regression using the geodesic equation on a torus. Could anyone give me a helpful advise on this problem? I would definitely appreicate your reply. Sincerely, SUNGSU KIM [[alternative HTML version deleted]]

Friends-- I'm stumped! Cannot get mount.cifs to work over a tun connection. How would you trouble-shoot this? 1. It cannot be openvpn causing the problem: I can ping across the connection both directions on all machines. 2. It cannot be samba causing the problem: I can mount.cifs the smb shares on the lan (using the identical credentials file) without any issue. 3. Have iptables

Hallo I am going through the paper on Torus randomization by Kyle E. Harms torus randomization is an alternative to Chi-sq test of Independence When the assumption of independence within the groups is violated i want to know that Is there any library regarding torus randomization Someone said me that its in Utility.r but i could not find out this please help me in this regard Shubham Surendra

Hi, this reminds me of my troubles of setting up samba BDC at remote company branch. Connection was done by IPSEC tunnel between 2 mikrotik routers. Thing was, ipsec supports only unicast, but not multicast,nor broadcast. Solved it by adding L2TP tunnel that support the above mentioned mechanisms. So ended up with the l2tp (which has very weak encryption and is very old and vulnerable)

Hello, I have 2D-data on a torus, i.e. they are scattered within [0:2pi) and are supposed to be periodic with period 2pi. Is there a way in R for a kernel density estimation for such data? I found this article http://www.dmqte.unich.it/personal/dimarzio/density46.pdf but a) I don't fully understand the article (my knowledge in statistics is poor) b) I did not understand which Eq.

Hi all, I am running R 2.5.0 under Windows XP Media Center Edition. Here's a problem that's been stumping me for a few days now, and I can't find anything useful in the archives. I am using voronoi.mosaic (tripack package) to create proximity polygons for a study of vegetation competition and dynamics. The points lists are read in from a file for each plot, then 8 duplicates

Dear Dr. Bivand and R-users, I have a 5 by 5 grid, say, location[1:5,1:5], and I want to know the indices of 8 neighbours of each cell. For example, for location[2,2], its neighbour coordinates are [1,1:3], [2,1], [2,3] and [3,1:3]. Sometimes I also need to remove edge effects (torus = TRUE). I have tried "cell2nb" function in your spdep package. Here's my example: > neigh

Hi all, I'm currently implementing quasi random generation (torus) on R (package randtoolbox available on CRAN). Even if it is not a great idea, I decided to use the machine time to initiate the seed. So when the seed is not specified by the user, the pkg uses the time machine time. Hence the following R code should produce different uniform variates : > for(i in
