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?

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

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!

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

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...)

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

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

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 MMX and Mac OS X Intel
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"

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
