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

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:

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

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

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

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

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

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, I'm happy to announce I developed a Multi-Threaded version of the Theora encoder. I changed the Motion Vector Search part of the algorithm to be executed in parallel. I've chosen the Motion search part after a careful set of profilings that shown that the Motion Vector Search is responsible by 70% of CPU-time on average and up to 95% of CPU-time in some cases. I also have chosen

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

Hi, This email is to inform what I have been doing since the mid-term. After the mid-term I worked on a pipeline implementation with OpenMP. As I said before I did a pipelined implementation of these functions: (c_dec_dc_unpredict_mcu_plane + oc_dec_frags_recon_mcu_plane) and (oc_state_loop_filter_frag_rows + oc_state_borders_fill_rows) as explained in my previous email. But the results were

On your document here: http://web.mit.edu/xiphmont/Public/theora/demo.html you show the result of the improved rate managemet in the theora codec. Can you tell which are the encoders that produced the two video matrix-580.ogg

Hi all, Attached is a trivial patch that speeds up encoding for key frame only streams. It skips the motion vector search which is not needed when there are never going to be any delta frames. It was made against thusnelda SVN revision 14589. Tested on Fedora 8 x64_64. -Phil -------------- next part -------------- A non-text attachment was scrubbed... Name:

We are pleased to announce a new stable release of libtheora, the Xiph.org Foundation's reference implementation of the royalty-free Theora video format. This new release, version 1.1, codenamed Thusnelda, incorporates all of the recent encoder improvements we have been making over the past year, though some of the code had its genesis all the way back in 2003. It also brings substantial speed
