object.search(regexp)
This method is used to search for a match between a regular expression and the specified string. If a match is found, the search method returns the index of the regular expression within the string. If no match is found, a value of -1 is returned.
The first example of code below uses the search method to look for a match between the regular expression ‘rExp’ and the characters in the ‘myString’ string object and displays the resulting value in the browser. In the second example, removing the ‘i’ (ignore case) flag from the regular expression causes the value of the search to be returned as -1
Code:
myString = new String(”Go to DevGuru.com”)
rExp = /devguru.com/gi;
results = myString.search(rExp)
document.write(results)
Output:
6
myString = new String(”Go to DevGuru.com”)
rExp = /devguru.com/g;
results = myString.search(rExp)
document.write(results)
Output:
-1

Reference: https://wiki.ubuntu.com/ffmpeg
For a litany of legal reasons, ffmpeg does not come with all of the necessary things enabled for you to encode video for the iPod Video by default. Therefore, we need to build it from source and install some other libraries and programs, as well. Make sure you have multiverse and universe enabled.
sudo apt-get remove ffmpeg
sudo apt-get install liba52-dev libdts-dev libgsm1-dev libvorbis-dev libxvidcore4 \
libxvidcore-dev libdc1394-dev libfaac-dev liblame-dev libx264-dev libfaad2-dev libtheora-dev \
libsdl1.2-dev libmpeg4ip-dev
wget http://ffmpeg.mplayerhq.hu/ffmpeg-export-snapshot.tar.bz2
tar jxvf ffmpeg-export-snapshot.tar.bz2
cd ffmpeg-export-*
./configure --prefix=/usr/local --disable-debug --enable-shared --enable-gpl --enable-postproc \
--enable-swscale --enable-pthreads --enable-x11grab --enable-liba52 --enable-libdc1394 \
--enable-libfaac --enable-libfaad --enable-libgsm --enable-libmp3lame --enable-libtheora \
--enable-libvorbis --enable-libx264 --enable-libxvid
make
sudo make install
Trying to compile ffmpeg from svn gives the following error:
libavcodec/libx264.c: In function ‘X264_init’:
libavcodec/libx264.c:224: error: ‘X264_ME_TESA’ undeclared (first use in this…
Solved. Installing these two packages:
http://www.brloh.eu/ubuntu/libx264-dev_0.svn20080408-0.0ubuntu1_i386.deb
http://www.brloh.eu/ubuntu/libx264-59_0.svn20080408-0.0ubuntu1_i386.deb

Specifies a delay in seconds before the browser automatically reloads the document. Optionally, specifies an alternative URL to load. E.g.
<META HTTP-EQUIV="Refresh" CONTENT="3;URL=http://www.some.org/some.html">
or (HTTP header)
Refresh: 3;URL=http://www.some.org/some.html
In Netscape Navigator, has the same effect as clicking “Reload”; i.e. issues an HTTP GET with Pragma: no-cache (and If-Modified-Since header if a cached copy exists).
Note: If a script is executed which reloads the current document, the action of the Refresh tag may be undefined. (e.g. <body onLoad= “document.location=’otherdoc.doc’>)
