similar to: variable frame rate

Dear list I have managed to write a short program to evaluate data which is inputted from a csv file using the following x = read.csv("wms_results.csv", header=TRUE) All works fine but since I have a number of similar data files which have different names, I would like the program to allow me to input the file name, rather than having to edit the program. >From the documentation I

Hello, I have an r function that creates the following dataframe tresults2. Notice that column 1 does not have a column heading. Tresults2: [,1] estparam 18.00000 nullval 20.00000 . . . ciWidth 2.04622 HalfInterval 1.02311 pertinent code: results<-cbind( estparam, nullval, t, pv_left, pv_right, pv_two_t, estse, df, cc, tbox, llim, ulim, ciWidth,

Hello! I'm trying my hand at lattice representations; I would like to represent a continuous varaiable as function of 2 factors and therefore use the following: bwplot(x ~f1| f2) which works fine except that it plots black points at the value of the median. How can I remove them? Thanks Anne [[alternative HTML version deleted]]

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.

Hi everyone, I'm working on a WebM plug-in for Premiere. You probably already know that WebM is a Matroska container that uses Vorbis for audio compression. I'm pretty new to the world of audio compression and need some help. You can see my code here: http://github.com/fnordware/AdobeWebM First of all, I wonder if it's possible to seek to an exact audio sample in WebM. Whereas

I am wondering about doing video emails using Theora and speex my files size limit is 4Mbytes I can get 13 minutes of speech by using speex into 1.5MBytes I am looking at the current camera phones what is the.... frame size? frame per second (FPS)? video bitrate (Kbit/s)? audio bitrate (Kbit/s)? How do I create a Theora and speex file? Can the java Cortado play speex audio files? tom_a_sparks

Is there a portable flac recorder with line-in? tom_a_sparks Light travels faster then sound, which is why some people appear bright, until you hear them speak

Is there any way to get better encoding speed out of ffmpeg2theora? eg: <snip> Duration: 00:57:04.92, <snip> ET: 02:06:24 here is the command: ffmpeg2theora --soft-target -V303 -v4 -F25 -K25 --croptop 8 --cropleft 2 --cropright 2 -x360 -y288 --deinterlace --aspect 4:3 -H24000 -A56 --optimize "<filename.mpg>" also the bitrate, 300kbits == 297kb (3 kbit less)

Hi there, I have just read in the documentation that Theora doesn't support variable frame rates. I don't know whether it will support it in the near future and since I cannot code I don't really know whether this would be easy to implement. But I'd ask you to consider implementing variable frame rates. The reason for that implementation would come from the much smaller size

sorry, let me reword my question I would like to be able to time sync the image to the video (using CMML) is there any software that can do that (web-based)? and are there any web-based player that can play the video on left side and display the images on the right side (no flash)? tom_a_sparks --- On Sun, 6/12/09, Tom Sparks <tom_a_sparks at yahoo.com.au> wrote: > I have a theora video

hi guys, first of all, i'd like to ask if there any crossplatform software/service ( gui is also better, an online application like firefogg is great, or at least a command line tools for any platform) to combine theora videos, other than oggcat... i am doing some art projects that people should be able to remix featured theora videos and i find oggcat very usefull in theory but not in

I am looking at writing a program using php that after X number of days (eg 60 days) a speex file is created that has all the speex file in a set folder with a bit of text to speech between the file for id reasons the speex file in the folder are deleted once done based on what I have read (corrent me if Im wrong): I need to convert the speex files to wav files (executable program), then I can

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

I tried to encode some video from a DVD with encoder_example and ffmpeg2theora, and it looked great, except that with both encoders the A/V sync would drift noticeably after about 10 minutes, and by the end of a two hour movie it would be a couple seconds off. So instead of just whining about this and waiting for someone else to fix it, I decided to try to learn about what's causing the
