OK, so here's a first start. I've translated to intrinsics the asm I sent 1-2 days ago. The result is about 5% slower than the pure asm approach, so it's not too bad (SSE asm is 2x faster

Hi everyone, I just landed into the theora planet, as a game programmer, I searched for a free video fomat/codec and the theora choice became obvious. However I experienced rather bad performance (at least from a game programming point of view) After a couple a profiling, I discovered, as previous discused in a post found via Google, that the bottleneck is in the ogg library. An unsane part of the

Hello! I've played in the last couple of days with an idea of having (binary) 'xml-like' streams in Ogg. This would make possible having metadata: 1) be independant on the codec, 2) could be introduced at any time, not just in the header (consider e.g. while streaming radio statio you want to send the current's program name / the current song, etc.. with the stream without

Hi! I've seen many new standards on the Xiph page. Have you thought about creating something like "OggDisk", that would correspond to CD, DVD, BD... disks? I mean data structure (propably on any filesystem) that could be used for audio and video (and perhaps for images too?). Desired features: - Ogg centric - designed to be filesystem/disk type independant (so that you can use

Hello, I installed wine via 'yum install wine' from my command prompt on a new install of Fedora Core 5 (everything was updated via yum before I attempted this), and everything went well with that. Then, when I tried to install a game that I saw was in gold status on the apps db, it went through a list of fonts and installed them or something, but it wont install the game. The CD is

All, After months of intensive development, we're finally coming to a stopping point in our rewrite of the libtheora reference implementation. All major features for the 1.1 are in, so it's down to bug fixing now. Please try this first beta and give us feedback. Most notable is that the encoder's rate control is much more configurable, and more capable in each configuration than

Hi folks, We're gearing up to the next full release of the Vorbis codec; I've just tagged a release candidate in SVN in order to encourage wider testing toward final 1.1 release. This release includes the following updates: 1) Adoption of AoTuV and other tuning work by Vorbis developers outside of Xiph into the mainline codebase 2) New bitrate management code 3) bugfixes In more

It might be interesting for this list to know that we've never had more positive feedback for anything we've done on the website than the amount of nice feedback we've got since introducing our Ogg streams. Readers of this list might like to know that we've just launched another two stations onto the excellent Ogg Vorbis platform. Again, we'd ask for your help in publicising

Hello! Can someone tell me, what the return value of ogg_stream_pageout() _really_ means? Documentation (libogg-1.0 - 20000615) says: ... Return Values 0 means that there is not enough data yet to form a page. 0 means that the page was successfully submitted to the bitstream. ... Thank You very much!

Hi all, I just did a brief test with 3 different codec combinations: 1) ffmpeg sorenson/flv, mp3 audio in flv container 2) ffmpeg h264/vorbis audio/matroska 3) ogg/theora/vorbis using encoder_example Here are the results: 10721201 2010-10-16 14:46 origem1.flv 20731108 2010-09-13 23:04 origem1.mkv 33101703 2010-10-03 11:24 origem1.ogv as you can see, flv wins hands down, and it doesn't look

Hi, A few questions: Is libtheora strictly backward compatible with VP3? Can I set it up to shove raw VP3 data through and trust it to decode the same way as On2's open source code did, loop filters and all? Also, is libtheora just supposed to be a C-based reference implementation? I was looking through the code and noticed a distinct lack of any kind of optimizations. Naive tree-based

Hi there, I maintain the libvorbis, libogg and vorbis-tool package for Fink <http://finkproject.org/ >. Recently I had time to wonder about those again. In particular, since I was informed libsndfile self-tests fails with 1.2.0, but not with a version dubbed 1.2.1rc1 somebody sent me. Also trunk seems to contain security fixes.

Hi Lourens, I fixed the YUV conversion and added a 'skip-empty-bitplanes' feature. The latter is still buggy, I have to check this again. But images look mach better now, even if you use higher compression ratios. (try ./main 1500 150 150 for a 352x288 image -- the output becomes blurred, but how does it looks when you compress it using jpeg down to about 2kB ...). Source is available

Hello everybody, I am a new user discovering libvirt with KVM software. During my first VM creation, I saw an issue with virsh that I can't understand. I wanted to emulate another CPU than the classical qemu32 using virsh. So I used the virsh capabilites command to detect how is detected my CPU host which is an Intel Xeon E5410 and my problem is that this CPU is detected only with the

Hello! I have an application, that needs bitmap fonts. It is strange, than on one of my computers it runs well on wine (0.9.9), but on the other it complains about the fonts(*). If I set WINEDEBUG=warn+font, it says it is ignoring this font. I found the folowing section in wine-0.9.9/dlls/gdi/freetype.c: if(!FT_IS_SFNT(ft_face) && (FT_IS_SCALABLE(ft_face) || !(flags &

Hi, ALL: I install IPP(l_ipp_ia32_itanium_p_4_1_2.tar) and download the speech codeing (l_ipp-sample-speech-coding_p_4.1.008.tgz) then patch it (g729-041103.diff). My CPU is Centaur VIA Nehemiah with 998.715 MHz processor not INTEL CPU. I choose PIII as its CPU type when I modify Makefile under "G729-float". # For PIII OPTIMIZE= -O6 -mcpu=pentium3 -march=pentium3 -ffast-math
