Hi Jean-Marc, We already decided to use Marvell's 88F8618 platform, But I have few questions to you and listed it below, Q1, Can we implement the Speex Codec on Marvell 8618 for non-HW DSP of platform? Q2, Based on ARM9 CPU core, do you have any information to let me estimation the voice computing power for Speex codec? Sorry to bother your job again.... Best Regards Janus ( Freedom )

Hello everybody, I'm a new member of this mailing-list. My name is Remi BEAUDOUIN, I'm student in an engeneering school in France (ENSEIRB, Bordeaux), major Data and Image Processing. I'm currently doing my last internship before graduating in Thales Airborne Systems. I'm working on video compression and I have to choose the best way to encode and to embed it on a DSP TMS320DM642

Hello people My name is Felipe and I sent a proposal to the Google Summer of Code that the goal is to get a FPGA embeded system decoding Theora Streams in real-time. It was accepted and the mentor is the Ralph Giles. The proposal can be viewd here: http://atlas.lsc.ic.unicamp.br/~portavales/wp-content/uploads/2006/05/soc_proposal.txt There is also a presentation with a better division of the

Hello, ? I know that Theora is marketed as patent-free and free to use for any purpose, but a fellow over at Xvid.com told me that Theora in fact is based on MPEG tech, and therefore has some deep elements that people might eventually go after me for if I use it to encode commercially distributed video, and bundle the decode files with the game. Besides? that, I belive the license of theora allows

Hi all, I've patched theora-mmx to build on x86_64. The patch against SVN is attached. Basically all I did was to copy lib/i386 to lib/x86_64 and tweak the assembler code a bit: * added to each file: typedef unsigned long int ogg_uint64_t * converted all asm inputs to 64-bit in: dsp_mmxext.c, fdct_mmx.c, recon_mmx.c * left all asm outputs at 32-bit * I didn't patch dsp_mmx.c, since all

I did a quick test integration of theora into our engine and ran into a couple of issues listed below. .dsp files in the alpha 3 zip are in unix format. Additional include path for the static theora library project is wrong. Library relies on libogg - would be nice to have a single zip including all dependencies. dumpvideo sample relies on global structures being zero initialized though does

Hello all, On more than one occasion I have advocated the use of liboil over incorporating mmx code into libtheora. The two main reasons are: 1) To keep optimisation code in one place and out of the library. Everywhere else in the Linux world there is a move to centralise in order to co-ordinate experts and reduce redundancy. This reason does not seem to find a lot of agreement in Theora as it

I'd strongly advice to use a higher performance micro. Let's consider that you'd succeed in getting it working right after optimizations. The time you want to add other speex features or other

Are we interested, or ready for this? Andrew Seddon is offering to provide hardware to port Theora to the DSP Stamp. http://www.linuxdevices.com/news/NS4405077268.html John ---------- Forwarded Message ---------- Subject: RE: DSP stamp Date: Friday 29 October 2004 03:50 am From: "Andrew Seddon" <andrew.seddon@camsig.co.uk> To: "'John Kintree'"

Hejsan ! I am currently investigating new, more modern approaches to encoding video with depth data based on my old data format MPEG Z/Alpha in http://www.geofront.se/products_software_mza.php and became therefore interested in Ogg Theora, as an alternative to MPEG-4 encoding - what I would need is two video streams in one system stream (is that the right terminology in Ogg ?), and decode them

Our optimized Theora encoder for video-conferencing runs 960X720 @ 15fps using 60% of an Atom 1.6GHz cpu. That should easily? translate to around 320X240 @ 15fps on the GadgetPC, or even better.

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

Yes, the Theora codec is based on VP3, which is an earlier version of ON2's VP6 codec. Theora is currently at its alpha 3 release, and is stable enough to have been used already for streaming live video from a number of conferences, and for encoding several videos that can be found at www.theora.org. Development has progressed to the point that the value of the codec can be seen. That

Hi, Attached is a patch against 1.0alpha7 to speed up Theora decoding. It is about 15~20% faster in my test. It consists of following things: * MMX loop filter based on Rudolf Marek's patch in http://lists.xiph.org/pipermail/theora-dev/2005-August/002838.html * MMX IDCT based on Rudolf Marek's patch in http://lists.xiph.org/pipermail/theora-dev/2005-July/002816.html and the code in

My understanding -- Monty or Emmett, feel free to chime in if you think this is incorrect -- is as follows: www.theora.org is the home for all new releases of the Theora video codec (formally known as VP3). This includes the main OGG/Vorbis integration product, which Monty is working on personally, as well as the QT and Windows codecs, both legacy VP3 versions and new versions reflecting any

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

Hello all! i want to use Theora in a little video portal, because its free and open source and i want to contribute some code to get the Java Theora player (Cortado) more feature-rich. But now I'm stuck and hope that someone can point me into the right direction. I have videos stored in several formats (mostly H.264 or MPEG4) and use ffmpeg2theora to recode them on the fly. The recoded
