Screen Capture - Video Recording On WIndows 7/8 without downloading any free software.

Hi, 
There is a good way to do the screen recording like camstudio or VideoCaptureMaster without downloading any such free software.
Here is a way from the very popular Open Source : ffmpeg. 

Here are the instructions :

Download UScreenCapture for windowsx86 or x64 from http://www.umediaserver.net/umediaserver/download.html ( you will find it at the bottom of the page(almost)) and install it

Download ffmpeg from http://ffmpeg.zeranoe.com/builds/ for windowsx86 or x64
Unzip the Tar and Go to bin directory where ffmpeg.exe is lying and Open Command Prompt here
Run this command : 
ffmpeg -f dshow -i video="UScreenCapture" -vcodec libx264 -crf 0 -preset ultrafast -acodec pcm_s16le output.flv .

To terminate the recording press CTRL+C

The output file output.flv will be formed in the bin directory.

Choose any format .flv , .avi or .mp4.All can be played with the VLC player.
