Hi All I have a 128Kbs internet connection used for in-coming and out-going traffic. What tools do I need to manage the following services: http, ssh (scp), ftp, streaming audio, smtp, instant messenger. Q1. What is the best kernel to use at the moment and what other tools need to be installed. Internet -------- eth0 | Linux fw | eth1 ----------- internal LAN The Linux firewall will

Hi, I have some questions: 1) in the sources of the encoder_example (and of course in oggenc.c, too) I see a lot of dependance on ogg. I want to get totally rid of ogg and use the vorbis bitstream alone. From this reason stems the second question: 2) is there a definition of the vorbis bitstream somewhere? I don't need to know every single detail, just the informations necessary to

Hi nice Vorbis people, I've been following the work on Ogg and Vorbis for some time, and I've been very impressed with the work so far. I'd like to introduce myself and volunteer for some work as it's needed. I'm very excited about the prospect of developing open-source audio coding technologies that are not encumbered by patents, and think this has the potential to be very

Greetings Fellow Vorbis Gurus! How can I encode, using CDex, at a CBR (constant bit rate) rather than the VBR? Also, can one take a 128kbs MP3 file and re-encode it to ogg? If so, please explain the procedure. By the way, I'm using a Windows based system. Thank you! /jp/ dojpaul@coffey.com --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage:

Hi List, Just batting a few ideas around here, but would it be possible to include in to the codec, estimation for common video artifacts that occur in the analogue world? For example, anything that's gone through a composite stage will likely have dot-crawl and false colour - if we can recognise this effect in the encoder, we can treat it as a special case. Other artifacts that come to

Estimados usuaRios: deseo hacer una consulta, debo realizar una prueba no paramétrica a un conjunto de datos que posee una variable de respuesta con tres factores que poseen interacción, o al menos debo probar ello. Es decir, realizar una prueba Scheirer-Ray-Hare o de Contrastes de rangos alineados. Estuve trabajando el paquete ARTool aunque no me queda claro

I hope this list is small enough for not beeing banned when introducing oneself. So... Hi, I just subscribed to the theora-lists. I'm from the XVID project, so I know a deal about video and MPEG-4 in particular, but nothing about Vorbis/Theora etc., That's why I'm here, because I'm interested in patent-free alternatives. I guess there is no documentation of the current status

Hello, We (Google) have been experimenting with configuration and adjustments to CELT-only Opus that give good results for compressing ambisonic audio signals [1]. Based on our results so far, we would like to use Opus to encode spatial audio. We hope to make it easy/possible to use libopus with other common tools and software modules (ffmpeg/libav in particular). Based on my reading of the

I currently have Icecast 2.3.1 running with Darkice on a Fedora Core 4 box (with the 2.6.14 kernel). We have three streams running (all mp3) @ 128kbs, 64kbs, and 24kbs. I am consistently seeing the following error: kernel: Unable to handle kernel paging request at virtual address ffffffff It does appear to be icecast causing the error. Oddly, when this first started showing up, it would

Hello, You guys might want to join this discussion. (And maybe some others too.) On the WhatWG mailing list, there's been a fury of e-mails about adding a <video> element to HTML5. They're talking about codecs and containers now. It might be helpful to have your representatives there. And help shape things. See ya ---------- Forwarded message ---------- From: Dave Singer

We need a two-way non-parametric ANOVA in order to analysis properly some ecological data, do you know any reference in R? or how to do it?

Moin, Two questions I have. Actually, the first isn't so much a question. It seems that `ogg123' is not able to play streams from stdin, at least not for me on FreeBSD. It also seems that with the patches way down below, it can play from stdin for me -- I handle stdin like http-transport and return the same values for seeking and the like, to avoid calls that fail, and so it works,

Hejsan ! I am currently investigating new, more modern approaches to encoding video with depth data based on my old data format MPEG Z/Alpha in http://www.geofront.se/products_software_mza.php and became therefore interested in Ogg Theora, as an alternative to MPEG-4 encoding - what I would need is two video streams in one system stream (is that the right terminology in Ogg ?), and decode them

Thank you very much! But how to deal with endianness in the case of bit stream? Some blocks (for example MinBlockSize) require 16bits (simply swap first and second), some block (e.g.MinFrameSize) require 3 byte-array to be reverted. Finally totalSamples is stored in 5 bytes ( only last 4 bits from first one byte are used). It was a real issue to make it little-endian (here is how I did it:

Hello, My name is Robin Mar?n and I have some questions about the Theora Codec/project... First of all I don't know if this is the right place to ask but I haven't found any Xiph/Theora forum or something similar... I don't even know if this is the right way of "posting" in mailists... But anyway... I discovered Theora just like a moth ago when the 1st alpha of Thusnelda

We've made a little change that changed the output of vorbis is there a way to check the accuracy of the output against the original output? I also asked this question in the irc ... Thanks, Tal.

Just wanted to let anyone know that might have checked out the generator before and couldn''t use it b/c you''re project required graceful degredation. Well its in there now. Thanks everyone and enjoy.

Hello, I would like to know how to find out the specifications (flow chart, transforms, tables, windowing operations, bitstream formatting) used to encode/decode audio in OggVorbis format. I mean something similar to the ISO/IEC 11172-3 document for MPEG-I and the like. Regards, ---------------------------------------------------- Jaime Andrés Aranguren Cardona SanJaaC Electronics

Hello Ilia, The FLAC format by nature is not a byte stream, it's a bit stream. Therefore, in order to parse it you need too build a bit-reading infrastructure. Eg. a class that accepts a byte stream, implements buffering, etc, etc, and supports reading a specified number of bits, not bytes as you are used to. There is quite a lot of bit logic there, but nothing too scary. Best Regards,
