FPGA implementation/ players speed?
Today I've got first video clips made by the camera and compressed "on the
fly" - 1280x1024x30fps. Image quality is far from perfect - I don't have
yet any way to preview images, and a single acquisition still requires a
bunch of commands. So I'm really close to have a camera that will be able
to serve the Ogg/Theora streams, now but will it be possible to play it on
a PC? I

VP3 Patch For xine
Hi,
Since a number of people are eager to try out the native VP3
decoder in xine, I have made a patch available, bz2-compressed:

To work with this patch:
1) Get the latest xine-lib from CVS. Visit this page for more details:

On2 VP3 codec for Intel macs
Hi all,
It's been a few years since I encoded a number of movies using the
VP3 codec (v3.2) on my Quicksilver PPC. Now I have a new Intel mac and I'd
like to play them. However, it seems that the codec offered on On2's
website is only for the PPC architecture. Does anyone know a workaround or
some other codec that works on the MacIntel platform? I'm using Quicktime
Pro 7.

Cross-Compiling VP3 lib on Linux
Hi,
I have been working with VP3 for some time now. Dan Miller from
On2 just told me about this list.
A few months ago, I managed to get On2's VP3 source snapshot to
compile under Linux, a feat that many have apparently attempted and
quickly abandoned. I compiled a small console app and the results of the
experiment are explained here:

Review of Mpeg-4 & on2's vp3...
The site:
http://www.techimo.com/articles/index.pl?photo=33&SID=12&tag=SNnb323
has a review & comparison of several mpeg-4 codecs, and they also
include vp3. (Be warned, it's a very big web page, due to all of the
image examples!)
Not really all that informative, but I thought somebody might be
interested in hearing about it.

VP3/QT: A new kdxlqt_CodecVersion patch
The new 3.2.6.1 codecs work great with QuickTime 6 (thank you!), but there's no way for an application to identify them. And since the older 3.2.1.x and 3.2.2.x installers will actually *downgrade* the installed version of VP3, it would be nice if an application could warn the user.
The attached patch increments kdxlqt_CodecVersion (and documents all the Component Manager arcana involved).

6.4 : How to enable epel and the rpmfusions??
I've installed 6.4 on an old T30 ThinkPad, and I'm
in the midst of setting it up. I can't seem to get an rpm of Pan for it,
nor even to do yum update.
Mousing around fedoraproject eventually got me to http://
rpmfusion.org/Configuration/ and from there to downloads for the free,
nonfree, and epel packages (along with a caveat that tells you -- *after*

Some questions about Theora IP
Hello Theora developers,
I'm doing some cursory research into Theora's IP status in preparation
for asking Apple to reconsider the possibility of shipping an
implementation. I have a few questions and I'm hoping knowledgeable
people can help out.
1) What are the terms of any patent licenses or disclaimers, and do
they have field of use restrictions or limitations on code for

Theora, MMX and optimisation
Hi everyone,
I just landed into the theora planet, as a game programmer, I searched
for a free video fomat/codec and the theora choice became obvious.
However I experienced rather bad performance (at least from a game
programming point of view)
After a couple a profiling, I discovered, as previous discused in a
post found via Google, that the bottleneck is in the ogg library. An
unsane part of the

VFW Codec
Hi everybody,
I'm currently writing a real time video conferencing tool for Windows and I
want to use the Theora Library for this purpose.
My questions are:
1.) is there a vfw implementation of theora
2.) if no, can I bundle the VP3 vfw codec that's available from On2's
website with my application
Best regards,

Re: DSP stamp
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

[Ffmpeg-devel] libavcodec/vp3.c compile problem (fwd)
Hi,
I don't know how much of the old VP3 codebase is incorporated into
Theora. I wrote ffmpeg's VP3 decoder from scratch but eventually ported in
the original VP3 IDCT function. A BSD conflict cropped up that I thought I
would pass along.

VP3 for xine 1.0-beta4
Hi,
Some of you may recall that I got the VP3 decoder working with the
xine multimedia player some time ago and posted a patch for anyone else
to try. I really messed up when I did that since I generated the patch
against some random CVS snapshot of xine-lib. I did better this time and
generated the patch against the latest release of xine-lib (1.0-beta4,
released today).

VP3 question
I get exceptionally bad image quality when I try to encode an
(uncompressed) AVI into a VP3 AVI
(actually I get this output no matter what format the source).
Please see this for a brief description of the problem:

What is wrong and what do I need to do?
Thanks!
