ffmpeg and OpenCV
Posted on
As of Oct 11, 2009, I reinstalled OpenCV and ffmpeg again on Ubuntu Jaunty. The previous installation procedure doesn’t seem to work. I can install OpenCV but it doesn’t cooperate happily with ffmpeg. I came across this wonderful guide and it more or less solves all my problems. Below repeats some of the steps described…
Embed all fonts

IEEE always requires authors to embed all fonts for the final pdf submission. After some googling, the commands that works for me under Ubuntu are dvips -Pdownload35 -t letter -G0 -o paper.ps paper.dvi ps2pdf -dMaxSubsetPct=100 -dCompatibilityLevel=1.2 -dSubsetFonts=true -dEmbedAllFonts=true paper.ps paper.pdf If you have eps figures that are generated from matlab, most likely some fonts in…

Video stuff in Ubuntu

Switching to Linux means relearning of many old skills. I finally got DVD Decrypter working again. I first tried installing it in a guest XP under virtualbox but it doesn’t work very well. It does do ripping but the output is all messed up somehow. On the other hand, installing using wine goes quite well…
DNS problem of virtualbox
Posted on
I wasted a couple hours today trying to figure out why my guest winxp has no connection. It is the third ubuntu machines that I have installed a virtualbox with a guest winxp. I am very satisfied with virtualbox. It is very fast and I can do almost anything I need for a window machine….
