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

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? Universal Multimedia Access and Open Standards <http://www.t4p.no/t4p.no/conference/media/Vaaler.pdf> tom_a_sparks Please avoid sending me Word or PowerPoint attachments. but instead use OpenDocument File Formats or use OpenOffice http://en.wikipedia.org/wiki/OpenDocument

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

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 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

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

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

I have tried to add a plunging to the "libtheora-1.0beta2" (network bandwidth measuring component was added) and Got it success for some far now the problem is when it is added the encoding process get extremely slow (around 20 seconds delay). I think that the problem is with my modified Makefile (some flag may have missed). the following is my modified Makefile.am which is in the

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

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
