Hi people, As I said before: I did the IDCT to run on the FPGA. My friends from university did the Reconstruction routines running on the FPGA. I'm helping with the LoopFilter, and it is almost there. (all VHDL) I did a small profiling of the libTheora running on a Altera Stratix II device: The processor used was the NIOS II with 8Kb of data and instruction cache, branch prediction and

Great news! Theora is running on FPGA. After almost a year of a great effort we have Theora validated on FPGA. Now I will try to integrated the hardware with a video controller to see the video! I completely implemented the ExpandBlock, CopyRecon, LoopFilter and UpdateUMVBorder functions. The ReconRefFrames function was partially implemented and the part before will run on a software compiled

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

Hello, First of all, I would like to say that my work that I wrote in the other email would be to do in hardware the functions: CopyRecon, LoopFilter and UpdateUMVBorder. These are modules that Leonardo had made, but it wasn't ok in FPGA. When I had a chat with Leonardo we were thinking in rewrite these module for to do this running in FPGA (to debug in a Hardware level is much more

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

Hi, Is somewhere alghorithm description of encoder process implemented in libtheora? May be some drafts? May be frame dataflow throw encoder stages?

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

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

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

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

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 different

Shows that as the MCU increases, the OpenMP extra overhead is amortized and OpenMP becomes as fast as the pthreads implementation. The last chart http://lampiao.lsc.ic.unicamp.br/~piga/gsoc_2008/systime.png Shows that both pthreads and OpenMP overhead decreases as what seems to be a logarithmic function of the MCU size. This was a great experiment, and from what I can conclude, the OpenMP

Hello, today I have the great pleasure of announcing Theora 1.0 beta1. http://downloads.xiph.org/releases/theora/libtheora-1.0beta1.tar.gz libtheora 1.0beta1 (2007 September 22) - Granulepos scheme modified to match other codecs. This bumps the bitstream revision to 3.2.1. Bitstreams marked 3.2.0 are handled correctly by this decoder. Older decoders will show a one frame sync error

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
