CELT bit error sensitivity
I am aware of a couple CELT users running the codec across a bit-error
channel where corruption takes the form of flipped bits (such as a raw
wireless link) rather than a packet-loss channel (like ethernet or an
IP network).
CELT has been designed to work reasonably well on both kinds of channel.
You can turn a bit-error channel into a packet-loss channel by
including a CRC across the entire

Theora blurriness in Windows players
I just finished using my mother's PC which is running Windows XP. I
downloaded & installed, or already had installed, the latest versions of
VLC Media Player (1.0.5), Media Player Classic - Home Theater (last
release was in August 2009), Miro (already installed), Mozilla Firefox
(3.6), Google Chrome (latest from website today), Opera (10.50 Alpha,
latest build from the website), and

Fwd: Theora developer question.
Hi Beorn,
1. replace "-v 7" to "--optimize --two-pass --soft-target -V 2000" you
will get about 200MB file size with no changes in quality.
2. try to use libtheora ptalarbvorm, it is in alpha state but has some
improvements. You can find comparison here:

if you use ubuntu 10.10 you can download precompiled libtheora and

Is there something like qt-faststart for theora?
One thing I noticed though when reading about ffmpeg to make the h.264
was that for internet, you could use qt-faststart to move some stuff (I
think called MOOV) to the front of the file allowing the file to start
playing before it was finished downloading.
That certainly helps quite a bit, I was wondering if there is a similar
type of thing for theora? Theora files I host do not seem to

Live webcam stream with Theora
Hey all,
I've setup a simple page that just displays a live webcam stream of me
at work, and it supposedly falls back onto Cortado if your browser
doesn't support the <video> tag. The URL is here:
http://media.basilgohar.com/stream/
There's been a lot of talk about live streaming and low bitrate
streams. Here is my command line (I've posted this before):

Add an intro to a theora file without re-encoding?
Hello,
I would like to add a introduction video (typically a title with fade-in
/ fade-out) at the beginning of an Ogg/Theora video. I generated this
intro video in Ogg/Theora from a sequence of png files.
I would need to do this in an automatic script, because I have many such
videos to process, and without doing any re-encoding step (which would
be very costly because my videos are huge).

AVI Theora?
Hello,
It's been a little while, but I've got some new info. I've tried doing this with Mencoder, ffmpeg, VLC player, and AVIdemux. None work. When I try to either convert a theora(ogm/ogv) file to AVI, while using?variations of "-vcodec copy" to keep theora comression, or just compress an AVI with Theora, it does one of several things, depending on settings and the program

Theora for webcam/conferencing use
Hey Theorans,
Yesterday and today I decided to try out broadcasting a video stream
using Theora from my computer's built-in webcam. I was pleasantly
surprised to find that, while maintaining a rate of less than 150kbps,
the stream was of quite a suitable quality sending 640x480 video at 15
frames per second. For now, this is video only, by the way, I did not
include any audio in the stream

Theora News
As a few may know, Theora will soon go 1.0 in the next release.
No more Alpha/Beta confusion. Theora is stable, and it's time we prove that.
Theora has also seen a new change in the form of its file extension
and MIME type.
File extension: .ogv
MIME type: video/ogg
Software developers are urged to change their programs to deal with
these changes accordingly. This is an important step on

Theora processing at server side : Removing non-needed frames
May somebody give me link for server side processing of ogg video by php or
ruby or anything else.
Let me tell my purpose,
I have made a image splitter of ogg video - You can view it at
http://jsbin.com/ihebo (basic coding )
just play the video and there is a button call "snapit", which will take
current frame.
At the end of this process, I will upload all timing info at server.
