'''FFmpeg''' is used mainly to convert and stream video. FFmpeg uses [http://en.wikipedia.org/wiki/Libavcodec libavcodec]. FFmpeg is developed under [[Linux]], but can be compiled and run under most operating systems.

== How to get it ==

svn co svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
cd ffmpeg
./[[configure]] && [[make]] && make install

== Formats ==

FFmpeg supports many formats and containers, including: mpeg-1, mpeg-2, DIVx, H.263, H.264, MP2, MP3, and MP4.

== How to use it ==

Here's an example how to convert ''example.dv'' to a .mpg [[file]]:
ffmpeg -i ''example.dv'' -f avi -vcodec mpeg4 -b 1800 -g 300 ''example.mpg''

== Errors ==

=== Unsupported codec for output stream #0.0 ===

ffmpeg is able to extract an audio file out of a video with the command :

ffmpeg -i v.mp4 -vn v.mp3

As a look at the web suggests this command very often gives the following error message :
;Error message :

Firefox

Colonna: /* Restoring a tab deleted with Ctrl W shortcut */ I am not sure the style is correct.

'''Mozilla Firefox''' (once known as "[[Firebird]]") is a cross-platform, [[open source]], free [[web browser]] available for [[Windows]], [[Mac OS X]], [[Linux]] and other operating systems. Unlike the [[Mozilla]] Suite, which includes a [[chat]] client, [[mail]] functions, and web page editor, Firefox is just a browser, and is considerably faster than Mozilla.

Since the introduction of version one of Firefox in the fall of 2004, Firefox is considered a viable alternative to Microsoft's browser, [[Internet Explorer]]. Thanks to features such as pop-up blocking, tabbed browsing, security features, Firefox has gained a substantial market share and the expense of Internet Explorer.

= History =
Firefox was originally known as Phoenix but was later renamed to Firebird and then, in February 2004, to Firefox, because of confusion with [[FireBirdSQL]].

= Distribution specific information =

== Debian ==
[[Debian]] firefox packages for testing/sarge and unstable/sid users are available in the standard Debian repository, get them with <tt>[[apt-get]] install mozilla-firefox</tt>. Debian stable/woody users can get a backported version [http://www.backports.org here]. A list of available plugins and locales packages can be found with <tt>[[apt-cache]] search --names-only mozilla-firefox</tt>

== Gentoo ==
[[GenToo]] users can [[instAll]] Firefox from a root prompt using [[emerge]], ie:

# [[emerge]] mozilla-firefox

or

# emerge mozilla-firefox-bin

(to get the official binary build installed).

= From the new Linux Installer =
Download the latest Linux installer from
[http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/ ftp.mozilla.org].
''(Note: The installer ends in '-installer.tar.gz')''

Extract it to a temporary directory, and go into the 'firefox-installer' directory. Now you must decide whether you want to install firefox system-wide, so that all computer users can use it, or whether to just install it for yourself. When you have finished the install you may delete the 'firefox-installer' directory.

== Installing Firefox for Personal Use ==

Run the script called 'firefox-installer', in the firefox-installer directory. (If you are using a gui tool, you should be able to simply click on it) Click next until you are given a choice where to install firefox. You will probably want to install it somewhere like '/home/yourname/programs/firefox'. From there the install should be simple. To run firefox you must either run '/home/yourname/*/firefox/firefox', or make a shortcut to it (varies depending on your desktop environment).

== Installing Firefox System-Wide ==

Open a terminal. Type in 'su' to login as the super-user. Use 'cd' to change to the directory where you extracted the firefox-installer (eg. <tt>cd /home/yourname/firefox-installer</tt>). then type in <tt>./firefox-installer</tt>. Click next until you are given a choice where to install firefox. To keep in line with linux standards, you will want to install it to '/opt/firefox'. From there the install should be simple. Once it is completed, go back to your terminal, and while still logged in as root, type in <tt>ln -s /opt/firefox/firefox /usr/local/bin/firefox</tt> (assuming you installed to /opt/firefox). This will mean any user can run firefox by simply typing in <tt>firefox</tt>, just like they were running any other program.

= From Their Binaries =
Mozilla makes nightly binaries available at http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/,
or get the latest release from
http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/

Untar it somewhere in your home directory with "tar -xvzf whatever.tar.gz"
you will have to run it with ./firefox from that directory, or you can create a [[shortcut]] to it.

= Plugins =
If you want browser plugins to work, symlink your main plugin directory contents to your new plugins directory. You will want to keep the existing libnullplugin, so rename it before doing so, and rename it back. Main plugin directories are often in /opt/mozilla or in /usr/lib/mozilla-version or similar.

The procedures for installing plugins such as Acrobat Reader are not well documented in the Firefox Help, but some good information is available at
http://plugindoc.mozdev.org/linux.html for 32-bit systems and http://plugindoc.mozdev.org/linux-amd64.html for 64-bit systems. Note in particular that you need to
use the program <tt>nspluginwrapper</tt> on 64-bit systems in order to utilize 32-bit plugins -- and 64-bit plugins don't yet exist.

To see what plugins you have installed, type <tt>about:plugins</tt> in the location bar.

= Firefox tips =
* Type <tt>about:config</tt> in your location bar to get a complete and editable list of Firefox's preferences.
**filter by:
***'''error''' and set the resulting setting to be true for error messages that show in the browser page instead of a pop up
***'''dom''', then set all of the dom.disable options to true if you want to have control over the content in the web browser (these should work with all sites, no site should depend on using these features, they are all [[security]] hazards when off)
***'''mouse''' set middlemouse.contentLoadURL to false, that way middle clickin on a tab will close it
***'''autoscroll''', set it to true, and you'll middle mouse button wont' paste personal information to a search engine everytime you accidentally click it, also does the autoscroll feature, which is an ergonmic feature, that will save you from finger strain. (IE on windows has this, and firefox on windows has it on by default)

* Creating a shortcut under KDE
** If you use KDE and would like a shortcut to firefox to appear under the "K" menu you can perform the following steps.
*** Right-click the "K" menu then select "Menu Editor". A "KDE Menu Editor" window appears.
*** Navigate to the location where you would like the shortcut to appear (ex: Internet>Web Browser). [Note: the default menu "folders" that appear in your K menu will differ depending on your linux distribution.] With the appropriate folder selected, right-click then select "New Item". Enter an appropriate name (eg: Firefox v1.0x) in the "New Item - KDE Menu Editor" dialog box then click OK.
*** With the new Firefox 1.0x menu item selected place your cursor in the Command field, then type in the proper path to the firefox executable. In the example provided above, this would be /opt/firefox/firefox
*** Select the proper icon for the FireFox shortcut by clicking on the Select Icon button (located just to the right of the "Name" field). In the Select Icon dialog box, select the Other Icons radio button, then browse to your /opt/firefox/icons directory and select the firefox .png file, click OK.
*** In the KDE Menu Editor dialog box, select FILE>SAVE, then select FILE>QUIT. Enjoy!

== Adblock extension ==
[http://adblock.mozdev.org/ Adblock] (''adblock.mozdev.org'') is an extension to Firefox that does exactly what you would expect it to do: it blocks advertisement banners, as well as flash animations and other similar nuisances.

To install it, follow [https://addons.update.mozilla.org/extensions/moreinfo.php?application=firefox&version=1.0&os=nt&id=10 this link] and click on the link that says "Install Now." If you have never installed an extenion before, you will most likely have to add <tt>update.mozilla.org</tt> to the list of sites that may install software onto your computer. To do this, click the button that says "Edit Options" and click the button labeled "Allow." Once the extension is done being downloaded and installed, restart Firefox to complete the installation.

In order to block the vast majority of internet advertisements, go to [http://www.pierceive.com/ pierceive.com] and follow the links to download a set of filters called Filterset.G. Right click on the latest version of the file and choose "Save link as" and save it to a suitable location on your hard drive. To install these filters, click on Tools, point to Adblock, and then click Preferences. Click on the button labeled "Adblock Options" and click "Import filters." Navigate to the location in which you saved the filter file and click "Open." This imports the filters.

There are some recommended settings for Adblock that will assist in enhancing your browsing experience. To active them, open the preferences panel (see above) and click on "Adblock Options." The option labeled "Obj-Tags" should be selected already. In addition to that, select the following three options, as well as "Keep List Sorted."

If an advertisement appears on a web site that is not blocked, it is very easy to block it for visits. Right click on the image and click the bottom option, "Adblock Image." A dialogue should open with the image's URL. You can click "OK" to block just that image. However, if you notice a pattern, for instance <tt>http://www.example.com/images/ads/banner1.gif</tt>, it may be beneficial to block <tt>http://www.example.com/images/ads/*</tt>.

Unfortunately, wildcard blocks like that can occasionally lead to accidental blocking of unintended images. For that reason, Adblock allows you to remove filters you've set previously. In our above example, if by blocking things using the filter <tt>http://www.example.com/images/ads/*</tt> made images disappear, you would want to delete that filter. To do so, open the Adblock Preferences (see above) and locate the filter on the list. It should be alphabetical, so locating it should not be difficult. Once you have found it, right click on it and either choose "Edit Filter" to change it and possibly correct it, or "Delete" to remove it outright.

= Firefox troubleshooting =
== Profile in use after power off ==
Firefox uses a file called lock in its profile to determine if the profile is in use. If Firefox is running during a power failure, this file is still there, and Firefox will fail with profile in use message. To fix it, find the lock file and delete it.

Running as user, execute

user@linuxbox / $ cd ; find .mozilla -name lock -exec rm -f {} \;

The above command will first change your current working directory to your own home directory (in this case, /home/user), then it will find all files called lock that are located in your .mozilla directory and any other subdirectory below it, and delete them forcefully. Or you can do the same thing with a file manager such as Konqueror.

Now firefox should work again.

== Restoring a tab deleted with Ctrl W shortcut ==
type '''Ctrl Shift T''' Then, the last deleted tab will be recovered. Moreover if you were editing some '''Html Form''' when you stroke '''Ctrl W''', you will come back to the same state as if you did nothing wrong (this is very useful when editing a Wiki page)

You will want to keep the existing libnullplugin, so rename it before doing so, and rename it back. Main plugin directories are often in /opt/mozilla or in /usr/lib/mozilla-version or similar.

The procedures for installing plugins such as Acrobat Reader are not well documented in the Firefox Help, but some good information is available at
http://plugindoc.mozdev.org/linux.html for 32-bit systems and http://plugindoc.mozdev.org/linux-amd64.html for 64-bit systems. Note in particular that you need to
use the program <tt>nspluginwrapper</tt> on 64-bit systems in order to utilize 32-bit plugins -- and 64-bit plugins don't yet exist.

To see what plugins you have installed, type <tt>about:plugins</tt> in the location bar.

= Firefox tips =
* Type <tt>about:config</tt> in your location bar to get a complete and editable list of Firefox's preferences.
**filter by:
***'''error''' and set the resulting setting to be true for error messages that show in the browser page instead of a pop up
***'''dom''', then set all of the dom.disable options to true if you want to have control over the content in the web browser (these should work with all sites, no site should depend on using these features, they are all [[security]] hazards when off)
***'''mouse''' set middlemouse.contentLoadURL to false, that way middle clickin on a tab will close it
***'''autoscroll''', set it to true, and you'll middle mouse button wont' paste personal information to a search engine everytime you accidentally click it, also does the autoscroll feature, which is an ergonmic feature, that will save you from finger strain. (IE on windows has this, and firefox on windows has it on by default)

* Creating a shortcut under KDE
** If you use KDE and would like a shortcut to firefox to appear under the "K" menu you can perform the following steps.
*** Right-click the "K" menu then select "Menu Editor". A "KDE Menu Editor" window appears.
*** Navigate to the location where you would like the shortcut to appear (ex: Internet>Web Browser). [Note: the default menu "folders" that appear in your K menu will differ depending on your linux distribution.] With the appropriate folder selected, right-click then select "New Item". Enter an appropriate name (eg: Firefox v1.0x) in the "New Item - KDE Menu Editor" dialog box then click OK.
*** With the new Firefox 1.0x menu item selected place your cursor in the Command field, then type in the proper path to the firefox executable. In the example provided above, this would be /opt/firefox/firefox
*** Select the proper icon for the FireFox shortcut by clicking on the Select Icon button (located just to the right of the "Name" field). In the Select Icon dialog box, select the Other Icons radio button, then browse to your /opt/firefox/icons directory and select the firefox .png file, click OK.
*** In the KDE Menu Editor dialog box, select FILE>SAVE, then select FILE>QUIT. Enjoy!

== Adblock extension ==
[http://adblock.mozdev.org/ Adblock] (''adblock.mozdev.org'') is an extension to Firefox that does exactly what you would expect it to do: it blocks advertisement banners, as well as flash animations and other similar nuisances.

To install it, follow [https://addons.update.mozilla.org/extensions/moreinfo.php?application=firefox&version=1.0&os=nt&id=10 this link] and click on the link that says "Install Now." If you have never installed an extenion before, you will most likely have to add <tt>update.mozilla.org</tt> to the list of sites that may install software onto your computer. To do this, click the button that says "Edit Options" and click the button labeled "Allow." Once the extension is done being downloaded and installed, restart Firefox to complete the installation.

In order to block the vast majority of internet advertisements, go to [http://www.pierceive.com/ pierceive.com] and follow the links to download a set of filters called Filterset.G. Right click on the latest version of the file and choose "Save link as" and save it to a suitable location on your hard drive. To install these filters, click on Tools, point to Adblock, and then click Preferences. Click on the button labeled "Adblock Options" and click "Import filters." Navigate to the location in which you saved the filter file and click "Open." This imports the filters.

There are some recommended settings for Adblock that will assist in enhancing your browsing experience. To active them, open the preferences panel (see above) and click on "Adblock Options." The option labeled "Obj-Tags" should be selected already. In addition to that, select the following three options, as well as "Keep List Sorted."

If an advertisement appears on a web site that is not blocked, it is very easy to block it for visits. Right click on the image and click the bottom option, "Adblock Image." A dialogue should open with the image's URL. You can click "OK" to block just that image. However, if you notice a pattern, for instance <tt>http://www.example.com/images/ads/banner1.gif</tt>, it may be beneficial to block <tt>http://www.example.com/images/ads/*</tt>.

Unfortunately, wildcard blocks like that can occasionally lead to accidental blocking of unintended images. For that reason, Adblock allows you to remove filters you've set previously. In our above example, if by blocking things using the filter <tt>http://www.example.com/images/ads/*</tt> made images disappear, you would want to delete that filter. To do so, open the Adblock Preferences (see above) and locate the filter on the list. It should be alphabetical, so locating it should not be difficult. Once you have found it, right click on it and either choose "Edit Filter" to change it and possibly correct it, or "Delete" to remove it outright.

= Firefox troubleshooting =
== Profile in use after power off ==
Firefox uses a file called lock in its profile to determine if the profile is in use. If Firefox is running during a power failure, this file is still there, and Firefox will fail with profile in use message. To fix it, find the lock file and delete it.

Running as user, execute

user@linuxbox / $ cd ; find .mozilla -name lock -exec rm -f {} \;

The above command will first change your current working directory to your own home directory (in this case, /home/user), then it will find all files called lock that are located in your .mozilla directory and any other subdirectory below it, and delete them forcefully. Or you can do the same thing with a file manager such as Konqueror.

Now firefox should work again.

== Restoring a tab deleted with Ctrl W shortcut ==
Simply type '''Ctrl Shift T''' Then, the last deleted tab will be recovered. Moreover if you were editing some '''Html Form''' when you stroke '''Ctrl W''', you will come back to the same state as if you did nothing wrong (this is very useful when editing a Wiki page)

Colonna: /* Restoring a tab deleted with Ctrl W shortcut */

'''Mozilla Firefox''' (once known as "[[Firebird]]") is a cross-platform, [[open source]], free [[web browser]] available for [[Windows]], [[Mac OS X]], [[Linux]] and other operating systems. Unlike the [[Mozilla]] Suite, which includes a [[chat]] client, [[mail]] functions, and web page editor, Firefox is just a browser, and is considerably faster than Mozilla.

Since the introduction of version one of Firefox in the fall of 2004, Firefox is considered a viable alternative to Microsoft's browser, [[Internet Explorer]]. Thanks to features such as pop-up blocking, tabbed browsing, security features, Firefox has gained a substantial market share and the expense of Internet Explorer.

= History =
Firefox was originally known as Phoenix but was later renamed to Firebird and then, in February 2004, to Firefox, because of confusion with [[FireBirdSQL]].

= Distribution specific information =

== Debian ==
[[Debian]] firefox packages for testing/sarge and unstable/sid users are available in the standard Debian repository, get them with <tt>[[apt-get]] install mozilla-firefox</tt>. Debian stable/woody users can get a backported version [http://www.backports.org here]. A list of available plugins and locales packages can be found with <tt>[[apt-cache]] search --names-only mozilla-firefox</tt>

== Gentoo ==
[[GenToo]] users can [[instAll]] Firefox from a root prompt using [[emerge]], ie:

# [[emerge]] mozilla-firefox

or

# emerge mozilla-firefox-bin

(to get the official binary build installed).

= From the new Linux Installer =
Download the latest Linux installer from
[http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/ ftp.mozilla.org].
''(Note: The installer ends in '-installer.tar.gz')''

Extract it to a temporary directory, and go into the 'firefox-installer' directory. Now you must decide whether you want to install firefox system-wide, so that all computer users can use it, or whether to just install it for yourself. When you have finished the install you may delete the 'firefox-installer' directory.

== Installing Firefox for Personal Use ==

Run the script called 'firefox-installer', in the firefox-installer directory. (If you are using a gui tool, you should be able to simply click on it) Click next until you are given a choice where to install firefox. You will probably want to install it somewhere like '/home/yourname/programs/firefox'. From there the install should be simple. To run firefox you must either run '/home/yourname/*/firefox/firefox', or make a shortcut to it (varies depending on your desktop environment).

== Installing Firefox System-Wide ==

Open a terminal. Type in 'su' to login as the super-user. Use 'cd' to change to the directory where you extracted the firefox-installer (eg. <tt>cd /home/yourname/firefox-installer</tt>). then type in <tt>./firefox-installer</tt>. Click next until you are given a choice where to install firefox. To keep in line with linux standards, you will want to install it to '/opt/firefox'. From there the install should be simple. Once it is completed, go back to your terminal, and while still logged in as root, type in <tt>ln -s /opt/firefox/firefox /usr/local/bin/firefox</tt> (assuming you installed to /opt/firefox). This will mean any user can run firefox by simply typing in <tt>firefox</tt>, just like they were running any other program.

= From Their Binaries =
Mozilla makes nightly binaries available at http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/,
or get the latest release from
http://ftp.mozilla.org/pub/mozilla.org/firefox/releases/

Untar it somewhere in your home directory with "tar -xvzf whatever.tar.gz"
you will have to run it with ./firefox from that directory, or you can create a [[shortcut]] to it.

= Plugins =
If you want browser plugins to work, symlink your main plugin directory contents to your new plugins directory. You will want to keep the existing libnullplugin, so rename it before doing so, and rename it back. Main plugin directories are often in /opt/mozilla or in /usr/lib/mozilla-version or similar.

Awk

2010-10-16T10:20:57Z

Colonna: added link to paste and corrected minor errors

[[awk]] is a [[command]] for string operations. For example, it allows you to show only the second ''column'' of a file. awk is not a simple command, but rather a programming language on its own. awk and gawk (for GNU awk) are used synonymously.

== Usage ==

When <tt>awk</tt> is run, it is given two forms of input, the ''program'' and the ''data''. The program can be typed directly on the [[command line]] or stored in a file and accessed with the <tt>-f</tt> option. The data comes from [[file]]s listed on the command line or from [[stdin]] if none are listed. The first example has the script on the command line with input from a file, while the second example uses an external program to create the input data and pipes into <tt>awk</tt>, which uses an external script as the program.

$ awk '{ print $1; }' ''datafile''

$ ''makedata'' | awk -f ''myscript.awk''

<tt>awk</tt> scripts that are saved in files can be executed directly by placing the proper [[shebang]] line at the beginning:
#!/bin/awk -f
'''Important note:''' use the exact path of your awk (available from typing "<tt>[[which]] awk</tt>") if it is not named <tt>/bin/awk</tt>.

=== How to ===

==== How to merge two files skipping some columns ====

[[cat]] >file_1<<eof
O11 0.081
O12 0.341
O13 0.343 eof

[[cat]] >file_2<<eof
O11 0.105
O12 0.415
O13 0.327 eof

[[paste]] file_1 file_2 | '''awk '{print $1" "$2" "$4}''''
O11 0.081 0.105
O12 0.341 0.415
O13 0.343 0.327

Paste file_1 and file_2 skipping column 3 from resulting file.

== Language structure ==

An awk program consists of a series of statements each consisting of a ''pattern'' and an ''action''. Awk reads the input (whether [[file]]s or data [[pipe]]d from [[stdin]]) line-by-line automatically. For each line of data, if the ''pattern'' is true, the ''action'' is executed. There are a few special patterns. The <tt>BEGIN</tt> rule is executed first, before any input is read, and the <tt>END</tt> rule is executed last, after the end of all input. Some complicated awk scripts consist of only a <tt>BEGIN</tt> rule and use <tt>getline</tt> to read the input data. If ''pattern'' is empty, the ''action'' is always executed. If ''action'' is empty, awk echos the line.

The pattern can be a [[regular expression]] enclosed in slashes ('/'), in which case it is considered true if the input line matches (i.e. contains matching text) the pattern. The expression <tt>/^[^#]/</tt> would select all lines not beginning with a pound sign. The pattern could also be an awk expression, e.g. <tt>(NF>5)</tt> to select all lines with more than 5 words.

Whenever a line of input is read (whether automatically or with <tt>getline</tt> [http://www.gnu.org/software/gawk/manual/html_node/Getline.html]), the line is split into words. The first word is assigned to <tt>$1</tt>, the second <tt>$2</tt>, etc. This makes it easy for awk to deal with columns of data. The variable <tt>NF</tt> is set to the number of words. <tt>$</tt> is an awk operator, so the "number" can be the result of any expression. <tt>$NF</tt> is the last word on the line.

Truly remarkably power in awk can come from use of dynamic arrays, especially when combined with regular expressions. This can allow for complex queries across many files with collection and collation of results as shown in the following example for the query "what are the first word of all lines and how often do they occur?"

This example shows several power features:
<ul>
<li>selects all lines not starting with <tt>#</tt></li>
<li>separates a matching line into multiple words</li>
<li>uses each word as index into wordcounts array</li>
<li>END clause, summary processing when all input is done</li>
<li>sort indices using asorti() and output counts</li>
</ul>

as:
<pre>
/^[^#]/{
w=match($0,/([a-zA-Z0-9_$]+)/,thisline);
for(i=1; i<=w; i++) {
wordcounts[toupper(thisline[i])]++;
}
}
END {
n = asorti(wordcounts, words);
for (i = 1; i <= n; i++) {
printf("%14s - %4d\n",words[i],wordcounts[words[i]]);
}
}
</pre>

If you save the above example as a file, in this case <tt>words.awk</tt>, then scanning a group of files can be as easy as:

<pre>
awk -f words.awk *.txt
</pre>

Add more complex regex criteria, use printf() for debugging, collect different arrays of results, see split() for further parsing, these and so many more features make <tt>awk</tt> one of the most powerful of scripting tools.

Awk

2010-10-16T10:03:46Z

Colonna: moved paragraph "How to" after "Language structure"

[[awk]] is a [[command]] for string operations. For example, it allows you to show only the second ''column'' of a file. awk is not a simple command, but rather a programming language on its own. awk and gawk (for GNU awk) are used synonymously.

== Usage ==

When <tt>awk</tt> is run, it is given two forms of input, the ''program'' and the ''data''. The program can be typed directly on the [[command line]] or stored in a file and accessed with the <tt>-f</tt> option. The data comes from [[file]]s listed on the command line or from [[stdin]] if none are listed. The first example has the script on the command line with input from a file, while the second example uses an external program to create the input data and pipes into <tt>awk</tt>, which uses an external script as the program.

$ awk '{ print $1; }' ''datafile''

$ ''makedata'' | awk -f ''myscript.awk''

<tt>awk</tt> scripts that are saved in files can be executed directly by placing the proper [[shebang]] line at the beginning:
#!/bin/awk -f
'''Important note:''' use the exact path of your awk (available from typing "<tt>[[which]] awk</tt>") if it is not named <tt>/bin/awk</tt>.

== Language structure ==

== Usage ==
* Create a file '''robots.txt'''
* This file must be accessible via HTTP on the local URL "/robots.txt"

=== Format ===
<field>:<optionalspace><value><optionalspace>

'''User-agent:''' <The value of this field is the name of the robot>
'''Disallow:''' <The value of this field specifies a partial URL that is '''not to be visited'''. This can be a full path, or a partial path; any URL that starts with this value will not be retrieved.>
'''Request-rate:''' <maximum rate>
'''Visit-time:''' <to define a visit time range>
'''Crawl-delay:''' <to wait between successive requests to the same server>

=== Examples ===
The examples below are taken from [http://www.robotstxt.org/orig.html robotstxt.org]

The following example "/robots.txt" file specifies that no robots should visit any URL starting with "/cyberworld/map/" or "/tmp/", or /foo.html:

* robots.txt for http://www.example.com/

User-agent: *
Disallow: /cyberworld/map/ # This is an infinite virtual URL space
Disallow: /tmp/ # these will soon disappear
Disallow: /foo.html
Request-rate: 1/5 # maximum rate is one page every 5 seconds
Visit-time: 1000-1200 # only visit between 10:00 and 12:00 UTC (GMT)
Crawl-delay: 10 # 10 seconds to wait between successive requests to the same server

This example "/robots.txt" file specifies that no robots should visit any URL starting with "/cyberworld/map/", except the robot called "cybermapper":

* robots.txt for http://www.example.com/

User-agent: *
Disallow: /cyberworld/map/ # This is an infinite virtual URL space

* Cybermapper knows where to go.
User-agent: cybermapper
Disallow:

This example indicates that no robots should visit this site further:

# go away
User-agent: *
Disallow: /

Mencoder

2009-12-20T23:10:01Z

Colonna: /* Using Mencoder */

mencoder ([[MPlayer]]'s Movie Encoder) is a simple movie encoder. It encodes to MPEG-4 (DivX/XviD), one of the libavcodec
codecs and PCM/MP3/VBRMP3 audio in 1, 2 or 3 passes. Furthermore it has
stream copying abilities, a powerful filter system (crop, expand, flip,
postprocess, rotate, scale, noise, rgb/yuv conversion) and more.

''From FreeBSD Handbook''

= Using Mencoder =
Before using mencoder it is a good idea to familiarize yourself with the options from the [http://en.wikipedia.org/wiki/Html HTML] documentation. There is a manual page, but it is not very useful without the HTML documentation. There are innumerable ways to improve quality, lower bitrate, and change formats, and some of these tricks may make the difference between good or bad performance. Here are a couple of examples:

To convert a .dv video stream you got e.g. from your [[CamcOrder]], you can issue:
$ mencoder test.dv -o test.avi -vf pp=ci -oac lavc -ovc lavc

-oac is the output audio codec, -ovc is the output video codec, -vf pp=ci makes a '''c'''ubic '''i'''nterpolation which is fine if your camcorder does [http://en.wikipedia.org/wiki/Interleaving interLeaving].

Improper combinations of command line options can yield output [[file]]s that are unplayable even by [[mplayer]]. Thus, if you just want to rip to a file, stick to the -dumpfile in mplayer.

To convert input.avi to the MPEG4 codec with MPEG3 audio encoding ([[audio]]/[http://lame.sourceforge.net/ lame] is required):
$ mencoder input.avi -oac mp3lame -lameopts br=192 \
-ovc lavc -lavcopts vcodec=mpeg4:vhq -o output.avi

This has produced output playable by mplayer and [[xine]].

input.avi can be replaced with dvd://1 -dvd-device /dev/[[dvd]] and run as root to re-encode a DVD title directly.

== Adding subtitles to a DivX file ==

To add '''iso-8859-1''' encoded subtitles from mymovie.srt file to mymovie.avi :
$ mencoder -sub mymovie.srt -ovc lavc -subcp iso-8859-1 -oac copy -o mymovie2.avi mymovie.avi

SIP address

2009-11-01T12:38:16Z

Colonna: typo

Like an email address it is an address used by the Session Initiation Protocol (SIP) to reach someone on the net.

It also has two parts separated by an '''@'''
#the user name (ex : doe)
#the provider name (ex: ekiga.net)

Thus John Doe address could be '''doe@[[ekiga]].net'''

How to run ekiga

2009-11-01T12:32:28Z

Colonna: /* when you and your correspondant have both a sip address */

== Usage ==
After having [http://wiki.ekiga.org/index.php/HowTo_install_Ekiga_packages install Ekiga] you can start by reading the official [http://wiki.ekiga.org/index.php/Documentation documentation] and [http://wiki.ekiga.org/index.php/FAQ FAQ].

To launch Ekiga in a terminal type :

ekiga

a new window will appear.with four tags ''''Talk''' '''Edit''' '''Show''' '''Help'''

=== if you do not have a [[SIP address]] ===

in the main ekiga window, click on the '''edit''' tag and then on '''''configuration assistant'''''
:give your name (ex : '''John Doe''')
:next give your username (ex : '''doe''') and password
::click on '''''I do not want to sign for the ekiga.net free service'''''
::follow the blue link '''''get an ekiga.net SIP account''''' from [https://www.ekiga.net/?page=register ekiga registration page]
::fill the page, accept and submit.
::You will receive a mail with your sip account (sip address) (ex : '''doe@ekiga.net''') and password.

=== when you have a [[SIP address]] ===

==== check your configuartion using the '''echo test''' ====
:in the main window click on tag '''show''' then on '''Services''' and '''echo test'''.
:you can tune your microphone and speakers using '''alsamixer and kmix''' and by clicking on the small sound icon in the right part of the ekiga window.

You can directly enter the '''echo test''' sip address '''sip:500@ekiga.net''' at the top of the ekiga window 
Right-click on the mouse on '''call''' fonction to set up the connection.

==== ask your correspondant to get a [[SIP address]] ====

:To be connected with a correspondant, this person must have its own [[SIP address]] (ex: smith@ekiga.net)
:You have to ask for this address. If he or she does not have yet a [[SIP address]] he or she has to use the same procedure as upper from its computer and its own ekiga installation to get one.

==== when you and your correspondant have both a sip address ====

Go to the main window and enter the [[SIP address|sip address]] of your correspondant (ex : sip:smith@ekiga.net) and right-click on the mouse on '''call''' fonction to set up the connection.

Alternatively, you can use the '''call history''' page in the '''show''' tag.

;Warning :
Ekiga is very lunatic :
*very often you will get error messages instead of a connection. In that case, kill it and restart it.
*sometimes if your correspondant can't call you, try to call him instead !

# [[How to run ekiga]]
# [[How to run ekiga behind a Dl-604 router]]
# [[ekiga]]
# [[sip address]]

all of them relatively short - with skype, for example, I do not need to read anything, it just works. --[[User:ThorstenStaerk|ThorstenStaerk]] 12:20, November 1, 2009 (UTC)
:I agree with your complaint. Skype is much much better than ekiga. In French univerities we are not allowed to use skype for some unclear reasons. Moreover, on Fedora 11 I could not install Skype. It is the reason why I spent so many time on trying to make it run.
:I you have further questions, I shall try to answer them.
:Please could you correct my english and recast the pages I wrote if necessary to fit LQ conventions.
:Best.--[[User:Colonna|Colonna]] 12:28, November 1, 2009 (UTC)

SIP address

2009-11-01T12:17:52Z

Colonna: initial

Like an email address it is an address used by the Session Initiation Protocol (SIP) to reach someone on the net. 
It also has to part separated by an '''@'''
#the user name (ex : doe)
#the provider name (ex: ekiga.net)

Thus John Doe address could be '''doe@ekiga.net'''

How to run ekiga behind a Dl-604 router

2009-10-31T15:15:14Z

Colonna: External links added

==Router configuration==

=== Dl-604 router ===
This information has been established using Fedora_11 and a Dl-604 router.

To configure the Dl-604 router:
*go to '''Advanced''' and '''Applications'''
*introduce 4 applications

{| border="1" cellpadding="2"
|+'''Advanced & Application'''
!Name
!Trigger Ports
!Public Ports
!Public Type
!Comments
|-
| SIP || 5000-5100 || 5000-5100 || UDP || SIP signalling, listen port: 5060
|-
| STUN || 3478-3479 || 3478-3479 || UDP || Outgoing traffic to the STUN server
|-
| H323 || 1720 || 1720 || TCP || H323 listen port
|-
| ntp || 123 || 123 || TCP || ???
|}

The 3 first applications are absolutely necessary 
The '''ntp''' application is not necessary to get ekiga working, nevertheless if not present you get an error message saying that ekiga is not able to configure its connection to the network.
