GSoC - Theora multithread decoder
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

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

Theora got extreamly slow (Makefile.am was changed)
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

Theora running on FPGA
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

ffmpeg2theora multi-threading
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:

Theora performance
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

SVN Theora FPGA
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

PostProcessingLevel field of PB_INSTANCE
What is the PostProcessingLevel field of PB_INSTANCE? When is it used? It is used for all Theora's video or it is just for legacy support with VP3? Thanks -- Leonardo de Paula Rosa Piga Undergraduate Computer Engineering Student LSC - IC - UNICAMP http://www.students.ic.unicamp.br/~ra033956

Theora playing on a FPGA
Hi all, Great news. On Thursday I finally play a video on FPGA. As I said the implementation is using the NIOS II processor. Andr? Costa is hard working to use the LEON processor. The video resolution is 96x80, because we have some FPGA internal memory constraints. I will try to use external memory to make possible decode a video of at least 320x240. The result can be see here:

Theora vs MPEG vs H264
Hi all, I have to compare the theora codec with MPEG and H264. I was googling and I found that the PSNR is a common used parameter. How can I do this with Theora?

Next step of Hardware Theora
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

Multi-thread Theora Decoder
Hi all, Does Theora Community have an interest in a multi-thread decoder implementation? I'm starting to work with multi-thread and I thought that Theora Decoder is a good choice for me, because I had been working with it in a FPGA implementation and I have experience with the library. I'm thinking in working with LoopFilter at first. Do you think I could start with it or there is a

dom0 - oom-killer - memory leak somewhere ?
Hello, I work in a hosting company, we have tens of Xen dom0 running just fine, but unfortunately we do have a few that get out of control. Reported behaviour : - dom0 uses more and more memory - no process can be found using that memory - at some point, oom killer kicks in, and kills everything, until even ssh the box becomes hard - when there is really no more process to kill, it crashes

Synchronizing passwords to Samba 4
Hi, I'm trying to synchronize user accounts from LDAP to Samba 4 AD (using LSC) but it seems that password update through ldap is not allowed. I failed to find details about it, but can someone confirm that unicodePwd cannot be read / wrote trough a LDAPS connection ? Is there any workaround ?
