Hello I would like to ask if it's possible to display Theora logo at http://ronja.twibright.com/sw.php I use Theora for automatically generated videos at http://ronja.twibright.com/3d/ If yes can I please have the master of the logo? I cannot use the small logo you have on the website. Thanks, Karel Kulhavy

Hi all, Just a stupid question The IDctSlow function on file idct.c has this line : ip[0] = (ogg_int16_t)((_Gd + _Cd ) >> 0); The ip[0] , _Gd and _Cd are of type ogg_int32_t My question is: The result of (_Gd + _Cd) can be a number with more than 16 bits ? (yes, it can be because they are int32, but the algorithm could guarantee something about that... I dont know...) If

...code used was the libtheora 1.0alpha8, but I think that my patch can be easily applied to the current libtheora 1.0beta1. I will clean-up the source code and maybe I could upload to the Theora SVN. Or send the patch to somebody. Cheers, Felipe -- ________________________________________ Felipe Portavales Goldstein <portavales at gmail> Undergraduate Student - IC-UNICAMP Computer Systems Laboratory http://www.students.ic.unicamp.br/~ra023772/

...ld be a completely hardware implementation or the integration with a nonproprietary processor. I will comment the code better and post in the SVN the quickest as possible. I will did a little movie with the video playing when I finish the integration with the VGA controller.

Are there any academic papers that promote theora? I know of one, are there more?

Is there a way to use multi-threading with ffmpeg2theora? Pretty much any type i'm ok with, including multi-threaded theora encoding or multi-threaded ffmpeg decoding, or using half of my cpu cores on ffmpeg decoding and the other half on theora encoding. Is there a way to do multithreaded thoera encoding? -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello people My name is Felipe and I sent a proposal to the Google Summer of Code that the goal is to get a FPGA embeded system decoding Theora Streams in real-time. It was accepted and the mentor is the Ralph Giles. The proposal can be viewd here: http://atlas.lsc.ic.unicamp.br/~portavales/wp-content/uploads/2006/05/soc_proposal.txt There is also a presentation with a better division of the hardware modules: http://svn.xiph.org/trunk/theora-fpga/doc/hard_theora.pdf Now, I'm working on it, and today I did a simple implementation of the IDctSlow procedure as a VHDL module. This...

Hi list, I just came across this site: http://web.mit.edu/xiphmont/Public/theora/demo.html I was wondering are these issues being addressed or will be addressed before the 1.0 release? Theora is like the only open sourced free code people can use, i will be nice if it performs close to other libs. please keep up the good work! -------------- next part -------------- An HTML attachment was

hi, i was trying to enable the mmx code on mac os x. to get to that point one has to replace some inline assembler code: .balign 16 -> .p2align 4 and replace .rept .. .endr with #defines. but to makes things more complicated apple's GAS does not support movsx instructions and thus the following line does not work: " movsx %%di, %%edi \n\t" [ more details at

...g wrong. In the specification of Theora, I saw the "VP3 Compatibility", but this shows the differences between original VP3 and the Theora Specification. What are differences between new and old VP3 codebase that timothy said to me? is there any document that shows the differences? Felipe Portavales and Leonardo Piga used the libtheora-1.0alpha6 in the reference model of Hardware Theora. is libtheora-1.0alpha6 using the new or old codebase? So, I thinks the most important task is the SDRAM controller, but the Integration with a processor and video controller are also important. What do you t...

Hi all, I apologize to not keep you up to date to what is going on with my project. Portavales has worked in a desk behind me and when we go to take coffee we talk about the project. Second I didn't know we have to discuss weekly, it was my fault. I should have read the rules. Sorry. At the first month, I studied the code and the Theora Beta implementation. The code is completely differ...

Hi, I did some improvements and some bug corrections in Theora FPGA code. I'd like to post this new version in the SVN. How can I do that? Thanks -- Leonardo de Paula Rosa Piga Undergraduate Computer Engineering Student LSC - IC - UNICAMP http://www.students.ic.unicamp.br/~ra033956

I just downloaded the libtheora-1.0beta2 and found some sentences in the spec that I believe are wrong: 1 - In section 6.4.4 "DCT Token Huffman Tables" step one says: "For each consecutive value of hti from 0 to 80, inclusive". As I understand there should be only 80 tables so shouldn't it be "0 to 79, inclusive" instead of 80?? 2 - In section 7.4 "Macro
