similar to: Reading framerate, height, width from Theora file

Hi, I have a question about the format of Theora bitstream header. It seems to me that there are differences between the specification[1] (version 2004 Oct 1) and its reference implementation in libtheora 1.0alpha3 released at 2004 Jun 1. I mean that... please refer to Section 6.2 'Identification Header Decode' in that specification[1] and the function

below is an rfc-style bitmap of the initial theora header. I've checked it against the spec and the code in libtheora; please double check :) I'm posting it here for those implementing demux stages (which necessarily don't use libtheora), and hence offering it for the spec. A typical demux stage just needs to pick out the FRN, FRD and KFGSHIFT fields, without going through the whole

Hallo all, I currently hacking on cheese an got problem with variable framerate produced by webcams (2-30fps). There is no problem to encode it with theora, but problem to mux it in ogg. Or at least to play produced file. There is no problem tu mux it in to matroska. My question is: should actually ogg support timestamps, also variable framerate? If yes: it seems to be some where broken. Here

Hi, This is probably a slightly odd question.... Is there anyway to decrease packetization? I'm using voip over a wireless network, and framerate is extremely important! Is it possible to reduce the framerate? Right now it's using about 90 frames/sec in to the phone and 40 frames/sec out from the phone (back to the PBX)

I've been getting max 10 FPS in Oblivion, even with extremely low graphics settings. Any ideas why? I didn't have any problems with running Oblivion on Windows, and even for Wine this seems quite low. I think it might be my graphics card drivers possibly. OS: Ubuntu 9.10 Karmic GPU: nVidia 8600M GT CPU: Intel Core 2 Duo @ 2 GHz GPU Driver: Version 195 (I got it by going System ->

http://www.youtube.com/watch?v=BcwieeBEySc My performance doesn't even come close to this even at low resolution and overclocked, and I have the 512Mb version of this card, this guy has the 256mb version and I have the same settings, i've seen people run some really high-end games on this like crysis at decent settings, (not high just decent). Does wine actually bottleneck performance on

Greetings to everyone. I understand that this problem may discussed many times, and i searched through forums but nothing solved my problem. In windows game runs perfectly with max details at 1680x1050. And i have something about ~50 FPS. But in Linux with same options i have ~18. I don't know why is that, when i'm trying to use native dll's in Wine config game won't startup. I

Hi, I'm a newbie here, so please don't threat me too bad. :D I wanted to ask you .. Yesterday I installed Linux Ubuntu 8.04 (Hardy) on my PC, it's the first Linux OS I use on it and I'm pretty confused, but I'm trying to make it work anyway. I installed WoW, using this FAQ https://help.ubuntu.com/community/WorldofWarcraft. I followed it, step to step, except for the

We build a Voip client with Iaxclient(Jiaxclient+Iaxclient2.1beta1+Theora1.0+libvidcap0.21),when we established video call with resolution 640X480(bitrate:500000,frameRate:11,fragsize:1472) in both sides,the CPU is consumed about 100%,the workload of Asterisk server is good at that moment.This issue does not exist with the resolution 320X240(bitrate:204800,frameRate:11,fragsize:1500), the

Hi all, I am trying to test DirectShow PushSource example from the SDK with Theora encoder and Ogg muxer (DirectShow filters of course) by using GraphEdit tool. My goal is capturing the screen as video by taking snaphot bitmaps continuosly (what PushSource eaxmple does) and giving them to the Theora encoder through the DS pipeline (next goal is transmitting this video **). My DirectShow graph is

Greetings, An update via cvsup (attempting to chase 5.4 stable) on 2006-02-20 @2:40 PM resulted in a couple of disappointments; 1) after re-building the kernel (cvsupped the SRC on SMP as well) and installing it. I performed a build/ install world and portupgrade -a. The portupgrade -a took 2 full days on a base of 246 installed ports. And resulted in a *465 installed ports base*. Ouch! It's

Dear helpers, I have a question about the SVG device. It works fine, the SVG file is indeed produced, only the graphic differs from the R window. In the SVG file the dashed line is just a regular plain one. My toy example is: library(RSvgDevice) devSVG("myplot.svg", width=10, height=10) plot(1:10) abline(v=5, lty=?dashed?) dev.off() Is there anything more (or different) I should do?

Hello R-people, I have a function which plots two figures next to each other using if(dev.cur()==1) x11(width=14,height=7) to create a new window and set the size of the window automatically if no device is open. This works fine in interactive mode but I don't know how Sweave gets the parameters for the figures, and right now the default behavior causes this figure to be square and the

Hi, I got this error while using png() function in RedHat 9.0. "Error in X11(paste("png::", filename, sep = ""), width, height, pointsize unable to start device PNG" It looks like the system lacks some library for graphics. Can anyone tell me which rpm I should install to have png() function work with out problem? Thanks ...
