I did some testing of vorbis codec (Winamp plugin) on a Pentium 166 MMX, and found that the performance is pretty good. I got 3 % cpu utisization if I turned dithering off, and 5 % otherwise. This was with a 138 kbit song. It's pretty long to mp3 performance that was 0 to 1 % on that machine for a 128 kbit song. Also vorbis seems to have a larger working set, because if I play two songs at

Hi, I hope you can help, I am in need of some assistance with the DirectShow filters for Theora. I have successfully created a working capture graph using OGG / Vorbis / Theora, however, when I add a Sample Grabber Directshow filter between the FFDShow decoder and Theora Encoder, this results in the video file being mirrored vertically. I have noticed that the original CaptureGraph was using

Hi So far when I have streamed Vorbis, the headers (the 3 first frames/packets) was not included in the stream, but communicated out of band typically in an SDP file as unparsed A-lines. Rethinking that concept, I'm wondering if it is really necessary to do it that way. Isn't it possible in a platform independent way to regenerate useable headers on the client side using just the

Hello. I'm trying to encode an Ogg Theora file from an unencrypted dvd using mplayer and encoder_example. I set up named pipes stream.wav and stream.yuv. I then run: mplayer -ao pcm -aofile stream.wav -vo null /dev/dvd & mplayer -vo yuv4mpeg -ao null -nosound /dev/dvd & encoder_example -v1 -a 1 stream.wav stream.yuv > lec1.ogg but I get the following error: File stream.wav is

Hello. How can I tell the number of frames in ogg/theora video file, without actually reading the file? Or, how can I tell its playing time (which is basically the same thing). I didn't find the information in THEORA_STATE, THEORA_INFO, but with the codec installed (illuminable oggcodecs), Windows Media Player shows the ogg/theora file playing time, before it starts playing the file.

Good day! Could you please explain me the following: In case of playback of video stream theora, MS Visual Studio .NET 2003 shows a warning message in every frame about the usage of not initialized variable MVect in the file decode.c (run-time check). In case of key-frames playback no warning appears. When I disable the run-time check, the video stream plays normally, but it is undesirable.

some of you may find this helpful: I've uploaded a short (5 second) raw clip in yuv4mpeg format, associated audio, and batch files to exercise the encoder & decoder examples. In addition I've included the file as compressed (test.ogg), and a longer version as well to test playback sync. Notes: to use MPlayer with the -vo yuv4mpeg option, you need to get the latest release and compile

Hi I'm trying push for companies and government institutions to start using Vorbis as an alternative to MP3 and to some extend AAC so they as a benefit can ignore rigid license schemes and expensive royalty payments. In principle it ought to be a downhill job, but it has turned out to be a lot more difficult than expected. The biggest obstacle for government institutions and to some extend

Hi all, I'm currently implementing quasi random generation (torus) on R (package randtoolbox available on CRAN). Even if it is not a great idea, I decided to use the machine time to initiate the seed. So when the seed is not specified by the user, the pkg uses the time machine time. Hence the following R code should produce different uniform variates : > for(i in

Hey all, I have an application (autopano: http://autopano.kolor.com/autopano_v103.zip) that I've ran on 32 bit systems for a while successfully.

There are no other console messages (such as WINE FIXMEs) before this. After

If anyone remembers, I was having issues running Jeskola Buzz with wine. I've fixed this by apt-get remove-ing the debian-unstable packages and compiling wine from source (wine-20020310) which has created the necessary registry files.
