can .ogg files play with any other codec
if i want to play a .ogg file, should i have the theora codec installed in
my machine...?
is theora the only compatible codec with ogg container format..?
i am using Ubuntu 7.04, with the default player (Totem Movie Player 2.18.1),
it is not necessary to install theora externally.
why is this,
with the totem player they included theora codec....?
or .ogg can be play with another codec...?

Gray scale video output from theora
hi all
I guess that *Theora* will convert the input color space (RGB or CMYK or
any) into YUV before it process and encode. (that means theora can operate
on several color space, but it get convert into YUV before process)
Is that true...?
I want to get a gray scale, encoded video output from the *Theora* encoder
while the input video is getting from a web cam (color input and gray scale

Theora and OLPC
Hi guys,
My name is Adir. I'm a Google Summer of Code student, and in addition to
that I will be working both with Xiph.org and with OLPC on optimizing
Theora's performance.
I'm in the list to get a shiny B4, but at the moment I can't do anything
since sending the laptop to my place involves some difficulties. Until I get
the laptop, I would like to hear from any of you, XO users

MMX patch to speed up Theora decoding
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:

theora-exp encoder issue
Hi,
I'm switching from the mainstream theora trunk to the exp one and I
encounter a problem with the encoder.
Every video I encode are played like a 'mosaic', I do not know how to
say that. The picture is just a bunch of coloured pixels.
During the encoding process the video stream is defined like that:
File stream.yuv is 320x240 15.00 fps 420 video.
Why 420 ? Why not YUV like for

libtheora 1.1beta1 release
All,
After months of intensive development, we're finally coming to a
stopping point in our rewrite of the libtheora reference
implementation. All major features for the 1.1 are in, so it's down to
bug fixing now. Please try this first beta and give us feedback. Most
notable is that the encoder's rate control is much more configurable,

Building theora 1.1.1 with mingw-w64-gcc 7.1 and msys
Hello,
I recently attempted to build theora 1.1.1 with mingw-w64-gcc 7.1 and
msys and it fails to build the encoder_example.c example program. There
are multiple declarations of the function 'rint'. The source file
created its own version of the function that rounds AWAY from zero.
MinGW-W64 has its own version of the 'rint' function, which does not
round away from zero.

VCD tracks to theora
Hello,
I am looking for a way to convert VCD tracks to theora.
I'd rather a command line tool.
What would you suggest me?
I already found I can do that with mplayer, by ripping to yuv and wav,
then using the encoder_example to compress to theora, but would there be
another better way?
