GSoC - Theora multithread decoder
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

Theora logo master
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,

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?

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!

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

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

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).

Thusnelda Video Quality
Wow.
Let me say that again, just in case you missed it.
Wow.
The quality looks to be on par with what I get out of H.264, but
Theora has the added benefit of free and open source software with no
patent worries so I can use it with a clean conscience. Thanks,
everyone.

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

Reading microsoft .xls format and openoffice OpenDocument files
1. I have used gdata::read.xls() with much happiness. But every now
and then it breaks. I have not, as yet, been able to construct a
mental model about the class of .xls files for which it works. Does
someone have a simple rule for predicting the circumstances under
which it will work?
2. Just like there is a read.xls(), it'd be great if we have a
read.ods() which directly

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?

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

What goes to Hardware ?
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

16 bits, cast on idct function
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...)

Problem when opening files after installing OpenOffice 3.1 on CentOS 5.4
Hi,
I have installed OpenOffice 3.1 downloaded from the openoffice.org
website on CentOS 5.4 x86_64.
The downloaded file is actually an archive containing RPMs.
I did not use their setup tool but installed directly the RPMs I was
interested in via 'yum localinstall' (my idea is in the future to put
them on a custom yum repository, so that they can be managed via
regular yum install /

Multi-Thread Theora Encoder
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

Linux Bridge + QoS Shaper HOWTO available
I''ve created a pretty complete HOWTO on creating a Linux Bridge (using
Fedora) to shape LAN <--> WAN traffic. It includes installation
instructions, a script to configure the bridge (which you install as a
service), and 2 scripts to configure the network interfaces using traffic
control.
