Theora over RTP/UPD
Hi, I'm trying to get Theora working with a video conferencing application we are developing. This application sends the audio content via RTP over UPD, and as one would expect, there is a draft for how a Theora stream is supposed to be wrapped into an RTP stream. http://svn.xiph.org/trunk/theora/doc/draft-ietf-avt-rtp-theora-00.txt The problem is that it is not obvious to me how the raw

CPU saving way to lower quality of Theora stream
Hi, is there a good concept to lower the quality of a Theora stream without completely reencoding it? For example to make a lower bitrate stream out of a higher bitrate stream on the fly on some sort of proxy server. I am thinking about something like requantization. If you think requantization is also the best (or the only) option for Theora please let me know. Kind regards, Franz

NHW Project - speed comparison with x265
Hello, I am very slowly working on the NHW Project.I recently made a speed comparison with x265 and wanted to share it with you. On my processor Intel Core i5-6400, in average the NHW encoder (totally unoptimized) is x10 times faster to encode than x265 (png decoding time removed), in average 30ms vs 300ms for a 512x512 24bit color image, and in average the NHW decoder (totally unoptimized) is

Echo cancellation with different sound card for speaker and microphone
I'm developing an application that have a video conference component. For that I need echo cancellation, and is looking around for algorithms/implementations of that, and the one in speex is an alternative. In the documentation for speex I find the following sentence however. "Using a different soundcard to do the capture and plaback will *not* work, regardless of what you may

Questions about encoder parameters.
I have almost finished integration of Theora into our videoconferencing program. Since a videoconferencing program is realtime, it is UDP-based and wraps the Theora stream in RTP (More on that later). The problem here is that most examples I could find, wraps the theora stream in ogg, and used over tcp or files. I send over UDP and clients need to be able to start in the middle of the stream.

Theora decoding performance
As far as my very limited knowledge goes the Theora video format is less complex than H.264 (High Profile for example). Please correct me if I am wrong. Does this also mean that I can expect that decoding a Theora stream is easier/faster to decode than a H.264 stream with comparable quality / or comparable bitrate? My (very practical) tests do show that it's easier for my computer to

Vectorizing sample()
I am simulating sickness among a group of families. Part of the task is to randomly draw who in the family will be sick, randomly drawing from family ID's where Dad =1, Mom = 2, Kid1 = 3, Kid2 = 4., etc. My census of Dads is of the form shown below.

Two overlaid density plots - Does order matter?
In the following code, the only difference between the two plots is the order the variables are plotted. In this case, the plot of "cdata.den" in plot #1 is different from its plot in #2. Specifically, "cdata.den" spans the x-axis from -5 to 30 in plot #1 and from 0 to 20 in plot #2. Does anyone understand why these two plots do not yield the same result? #Make density

fitting truncated normal distribution
Hello, I am a new user of R and found the function dtnorm() in the package msm. My problem now is, that it is not possible for me to get the mean and sd out of a sample when I want a left-truncated normal distribution starting at "0". fitdistr(x,dtnorm, start=list(mean=0, sd=1)) returns the error message "Fehler in "[<-"(`*tmp*`, x >= lower & x <= upper,

loglik and arima()
All - I am evaluating an arima(2,1,3) and arima(3,1,3) and notice the log-likelihood of the restricted model is higher than the log-likelihood of the unrestricted. Since these are nested models, I thought the unrestricted model would have a log-likelihood at least as large as that of the restricted model. Am I interpreting the "loglik" output incorrectly?

Linear least squares fit with errors in both x and y values.
HI, I'd like to perform a weighted linear least squares fit with R on data with varying errors on both vectors. I can do this with one axis using lm, but have no idea where to go from here. I've tried googling, but no idea. Any suggestions? Thanks, James

SAS language to R :interview
Dear List, Please find a frank interview with Phil Rack, creator of Bridge to R ( from both SAS and WPS interfaces). For those unaware of WPS- it is basically a SAS language compiler (read SAS code,writes SAS code,Reads and writes SAS datasets) ,priced at 660 $ a licence ( or estimated 10 times cheaper than Base SAS. The UK based WPC held, WPS doesnt have advanced statistical facilities like

queue simulation
Hi all, I have a multiple queing situation I'd like to simulate to get some idea of the distributions - waiting times and allocations etc. Does R has a package available for this - many years ago there used to be a language called "simscript" for discrete event simulation and I was wondering if R has an equivalent (or hopefully with graphics, something better!). Apologies if there
