Convert .flv to .mpg using ffmpeg

Image
By
Using ffmpeg :
  • libavcodec is a library containing all the FFmpeg audio/video encoders and decoders. Most codecs were developped from scratch to ensure best performances and high code reusability.
  • libavformat is a library containing parsers and generators for all common audio/video formats.

ffmpeg -i jokes.flv -ab 56 -ar 22050 -b 500 -s 320×240 jokes.mpg

jokes.flv is the file you want to convert, so the name must be the same as the source file.You can name jokes.mpg whatever you want as long as it has the .mpg extension.

-b bitrate: set the video bitrate in kbit/s (default = 200 kb/s)

-ab bitrate: set the audio bitrate in kbit/s (default = 64)

-ar sample rate: set the audio samplerate in Hz (default = 44100 Hz)

-s size: set frame size. The format is WxH (default 160×128 )

Using mencoder :

This might not work.

To convert flv (flash video) files to AVI using open source mencoder. To perform the conversion, you just need to type :

mencoder -oac copy -ovc lavc -o video.avi video.flv

You can convert the FLV files into other format too. In order to do that, make sure you have all the necessary codecs to perform the conversion. If you're in doubt, install w32codecs, add this line in your repository to enable w32codecs installation (assuming you use Ubuntu Edgy Eft).


deb http://packages.freecontrib.org/ubuntu/plf/ edgy free non-free
deb-src http://packages.freecontrib.org/ubuntu/plf/ edgy free non-free

Now you can use Linux as to do your video encoding stuff without much hassle.

Fastest way to send multiple drafts from gmail

By
People claim that the fastest way to send multiple email drafts is to use Gmail IMAP with email client like Outlook or Evolution or Thunderbird. But I have found this is not true. Because Thunderbird and Evolution etc. email clients treats the drafts as emails still to be edited. So it is not just simple select all and hit send. Each email draft has to be opened and sent separately. That is a lot of clicks and mouse movements, wasting precious time and energy. I have a better solution which involves minimum keystrokes and mouse usage. Efficiency booster technique for sending emails. If someone is feeling adventurous and want to try it from the Gmail interface itself, here's how to do it in the fastest possible manner. It involves using the mouse once. Select the first draft. Gmail would open a new email box and put the cursor inside the box to write. Press TAB once to go the Send button. Press ENTER to send. Now Gmail sends it and the box is gone but the highlight goes to the last...

Changing the font size of section headings in LaTex

By
You have several ways to do so: 1.- A direct redefinition of \section: \makeatletter \renewcommand\section{\@startsection{section}{1}{\z@}%                                   {-3.5ex \@plus -1ex \@minus -.2ex}%                                   {2.3ex \@plus.2ex}%                                   {\normalfont\large\bfseries}} \makeatother 2.- By means of the titlesec package: \usepackage{titlesec} \titleformat{\section}{\large\bfseries}{\thesection}{1em}{} 3.- By means of the sectsty package: \usepackage{sectsty} \sectionfont{\large} source : http://www.latex-community.org/forum/viewtopic.php?f=4&t=3245   Now, I would explain the titlesec package a bit more (because it seems easier to me and...
