Theora in stream directory
Hi All, I've got a plain Ogg Theora stream (no Vorbis) and just tried getting it listed at dir.xiph.org, which works but it's being listed as an "Ogg Vorbis" stream with no bitrate. I'm using libshout to send the stream to Icecast. Is there something I've missed or a bug in the directory browser? It may not expect a video-only stream? The stream is called

Can I recommend theora to my readers yet? Please?
Hi, I'm working on updates to the WWW FAQ (okay, it's a little much to use the singular in 2006, but it was the first!). Embedded multimedia has been a sore spot for a while. I've been recommending that people embed old-school MPEG, because it works in all players. But it's awful. Terrible bitrates. I'm on the verge of recommending SWF instead, even though it's a hideous

Seeking through Theora+Vorbis ogg file..
Here's the problem: I've rewritten large parts of the output code of cortado 0.1.0 with the following aims: 1. output to something SWT-like instead of AWT. 2. Speed it up a bit. In the rewrites I haven't restricted myself to java 1.1; the fact that it uses SWT all by itself makes it useless for applets anyway. The speedup worked very nicely; it's almost twice as fast as

Quicktime 2 Theora Transcoder's Nano-Howto
After a bunch of cumbersome testing I was able to transcode a Quicktime MOV file to OGG with theora and Vorbis. The method's a bit fumbly, but it works... It is automatable except for the initial audio decoding. Software used: Xine, oggenc, ffmpeg, ffmpeg2theora, oggzmerge Step 1: Get the video out of Quicktime ffmpeg -i infile.mov -b 5000 -f mpeg2video outfile.mpg Step 2: Get the video

Dropped / Duplicate Frames
Hi all, I've been playing with Theora this week and have hacked together a test program (http://www.firestorm.cx/live1/) that can encode live video (no audio) from a V4L* source that supports the YUV420 pixel format. Now encoding Theora ain't exactly a speedy process, and sometimes frames get lost during capturing. What I'd like to be able to do is tell libtheora that the next few

transcoding to theora from quicktime using xiphqt
Hi, I'm trying to convert some quicktime files into Ogg/Theora using the Xiph QuickTime Components version 1.8. The end goal is to stream these files using apache httpd and the cortado applet (and hopefully the embedded players that will be in Firefox soon). Using iMovie DV on OS X 10.4.11 (intel) I'm able to export as an ogg movie, however the resultant file has problems with audio on

New around - some questions (Cortado, editing Theora)
Hello, I am maintaining different resources related to Ogg Theora, both as a user and as a contributor to several local advocacy groups. I had a couple of questions: - Who should I ask / talk to about financing improvements to the Cortado applet (namely: bigger / more visible controls for the seek functions) ? - Are there any simple Ogg Theora editing tools or applications, similar to avidemux

Small utility to modify Theora file aspect ratio / frame rate / cropping
Hello, I encoded a bunch of theora video files from my DVDs. I thought for a long time that mplayer was broken because it displayed the aspect ratio wrong. Then I found out that the aspect ratio I was specifying was supposed to be the pixel aspect ratio, not the video aspect ratio. (This is extremely confusing and I urge you to change the semantics of encoder_example. I also urge you to check for

Pure Java theora implementation - LGPL
I've started working on a pure-java port of Theora under the LGPL, as a subproject of FMJ, the open-source implementation of JMF. It is similar to and dependent on the jogg/jorbis libraries from jcraft. The Cortado implementation is nice, but since it is GPL, that is too restrictive for FMJ, which is LGPL. This is, naturally, a large undertaking, and any help by anyone interested would

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

[Cortado] How to support seeking in on-the-fly generated Theora stream?
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.

theora video plugin ? videolan plugin?
hi, I'm Alexander a just a question ? is there a reason why there shouldn't be a web player for theora in Mozilla FireFox ? or Internet explorer ? I'm thinking to compile videolan player with theora support only and enable the web plugin interface, it would replace the cortado player and possibly provide a better alternative to flash video plugin in linux when somebody starts a

theora system layer format
hallo, is there any documentation available (or at least has any decision been made on this yet) what the system layer for theora will exactly look like? i guess it will be ogg, but afaik ogg itself is not very specific on how to pack different media format streams into one ogg stream, how to do a/v syncronization ... all the little details. on the other hand there is already such a

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): time ffmpeg -f
