Encoding paramaters...
I've got my encoder working now... and i put a proeprty page interface to
allow the user to set a few encoding paramters to start off with... but
changing the paramters doesn't seem to make barely any difference...
These are the defaults i'm using...
mTheoraInfo.target_bitrate=400000;
mTheoraInfo.quality=30;
mTheoraInfo.dropframes_p=0;
mTheoraInfo.quick_p=1;

Sampling encoder timings between libtheora-1.0 & libtheora-1.1beta3
As requested by Ralph in my introduction e-mail to this list [1], I've
gone ahead and done some sample test timings for encoding between
libtheora-1.0 and libtheora-1.1beta3, as available from the Theora
website [2].
So far, I've tested with 4 different files that I generated with content
I already have. The files, in brief, are the following:
1. planet-earth-360x240.yuv4mpeg - A

CVS compile problems
Hi,
I'm compiling theora from the cvs. I use it with mplayer.
I had run in these problems:
1. At make time I got that:
Making all in doc

make[1]: *** No rule to make target `testspec.raw', needed by `all-am'.
Stop.

help - Theora/Vorbis/Ogg, ogmmerge and ffmpeg2theora
Hi,
I'm probably being fairly stupid. But I did the following, starting with
the following two files:
# tcprobe -i vts_01.m2v
[tcprobe] MPEG elementary stream (ES)
[tcprobe] summary for vts_01.m2v, (*) = not default, 0 = not detected
import frame size: -g 720x576 [720x576]
aspect ratio: 16:9 (*)
frame rate: -f 25.000 [25.000] frc=3
# tcprobe -i vts_01.m2a

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

newest cvs and mplayer
Hi
The newest cvs let's mplayer segfault:
...
Opening video decoder: [theora] Theora/VP3
Segmentation fault
I don't get any infos more :(
A gdb backtrace don't work.
(mplayer is compile with --enable-debug=3)
When will the encoder_example implemented in mencoder ???
Would be nice because the yuv-data is soooo big on the HD ;)

Again, the newest theora cvs prevents mplayer from compiling:

New addition to FAQ
Greetings,
I was on IRC about 7 hours ago and suggested that the FAQ be updated slightly.
Rather than sit on my ass and complain I figured I'd ask a few people, and see
if the idea was worth the time.
Here's what Ive started with:
http://www.dimension.net.nz/theora.html
I'll be adding to it over the next 24 hours - mostly in the area of Playback
and Encoding.
Just threw it together

I was surprised with size of Theora files and thought
of feedback.
Following 1minute duration Theora and Xvid files were

Theora@GP2X possible?
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hello,
I just want to know whether it would be possible to play ogg-theora
videos on my favourite Handheld, the GP2X. For those of you who don't
know the GP2X yet there's much information about it on Wikpedia or on
http://wiki.gp2x.org/wiki/Hardware_Documentation . To make it short,
its an ARM-based Handheld which is able to play Xvid and DivX

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,
and more capable in each configuration than

blocky issue here with libtheora 1.1 20090806 (Thusnelda)
this sample is very blocky, the older version seems to do much better
and less blocky video. i'm not sure if my 1.9ghz 1 gb ram is the problem
here or the encoder has hicups on this new libtheora 1.1 20090806
(Thusnelda). please advice how to fix this or should i use the older
version. this encode was 2 pass with horrible output.

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"

libtheora 1.1 (Thusnelda) stable release
We are pleased to announce a new stable release of libtheora, the
Xiph.org Foundation's reference implementation of the royalty-free
Theora video format. This new release, version 1.1, codenamed
Thusnelda, incorporates all of the recent encoder improvements we have
been making over the past year, though some of the code had its
genesis all the way
back in 2003. It also brings substantial speed
