MYSQL:

+

mysql> create database forum; +mysql> GRANT ALL PRIVILEGES ON forum.* TO 'moderateur'@localhost +mysql> identified by 'mot_de_passe_du_moderateur';

+

The following will create a database named "intranet".

+

mysqladmin -p create intranet

+

Next, create the database user account that will be used to access the database.

+

mysql -p --user=root intranet

+

mysql> GRANT ALL PRIVILEGES ON . TO intranet@localhost +IDENTIFIED BY 'webcal01' WITH GRANT OPTION; +mysql> FLUSH PRIVILEGES; +mysql> QUIT

+

If you will be accessing MySQL from a different machine than the one running the web server, repeat the command above and replace 'localhost' with the hostname of the other machine.

+

Create the calendar tables using the supplied tables-mysql.sql file:

+

mysql -p intranet < tables-mysql.sql

+

In the above example, "intranet" is the name of your database.

+
+
CHANGE ROOT PASS
+

Alternativement, sur toutes les plate-formes, vous pouvez aussi choisir le nouveau mot de passe en utilisant le client mysql :

+
+
    +

  1. Stoppez et redï¿œmarrez mysqld avec l'option --skip-grant-tables comme dï¿œcrit plus haut.

    +
    2. +

  2. Connectez vous au serveur mysqld avec :

    +

    shell> mysql -u root mysql

    +
    3. +

  3. Exï¿œcutez la commande suivante dans le client mysql :

    +
    +
    mysql> UPDATE user SET Password=PASSWORD('nouveaumotdepasse')
    +

    -> WHERE User='root';

    +
    +
    +
    +

    System Message: WARNING/2 (tips.txt, line 259)

    +

    Definition list ends without a blank line; unexpected unindent.

    +
    +

    mysql> FLUSH PRIVILEGES;

    +
    4. +

  4. Aprï¿œs cela, vous devriez pouvoir vous connecter avec le nouveau mot de passe.

    +
    5. +

KERNEL CUSTOM

+patch -p0 linux-2.6.15 > patch-2.6.15-rt1-1
+
+api linux-source-2....
+cd /usr/src/linux/
+
+

Then run the following commands (please note that make dep is not needed any more for kernel 2.6):

+
+make-kpkg clean
+fakeroot make-kpkg --revision=custom.1.0 --append-to-version=rt9.yomguy --initrd kernel_image kernel_headers modules_image
+
+

ou:

+
+fakeroot make-kpkg --append-to-version=.rt8-yomguy --initrd kernel_image kernel_headers modules_image
+
+

If the compilation stops with an error, run:

+
+make clean
+
+

and then re-run the previous commands starting with:

+
+make menuconfig
+
+

Change the kernel configuration where the error occurs. If no error occurs you will find the new kernel as a Debian package called kernel-image-2.6.8.1_custom.1.0_i386.deb under /usr/src:

+
+cd ../
+
+

Now you have to install some packages that are needed by kernel 2.6. Add the following line to /etc/apt/sources.list:

+
+deb http://www.backports.org/debian/ woody module-init-tools initrd-tools procps
+
+

Then run:

+
+apt-get update
+apt-get install module-init-tools initrd-tools procps
+
+

If you are asked the following question: +"If you really want to remove modutils type 'yes':" +type yes.

+

It might also be necessary to update packages like bind9, quota, etc. - depending on your configuration. If you have problems with your existing packages try to get the appropriate package from www.backports.org. +Install your new kernel:

+
+dpkg -i kernel-image-2.6.8.1_custom.1.0_i386.deb
+
+

Create a ramdisk of your new kernel (otherwise your system will most likely not boot):

+
+cd /boot/
+mkinitrd -o /boot/initrd.img-2.6.8.1 2.6.8.1
+
+

We are almost finished now. Edit the image=/vmlinuz stanza of your /etc/lilo.conf and add the line initrd=/boot/initrd.img-2.6.8.1:

+
+###
+# Boot up Linux by default.
+#
+default=Linux
+#
+image=/vmlinuz
+        label=Linux
+        read-only
+        initrd=/boot/initrd.img-2.6.8.1
+#        restricted
+#        alias=1
+###
+
+

Run:

+
+lilo
+
+

to update your boot loader and reboot your machine:

+
+shutdown -r now
+
+

and if everything is ok your machine should come up with the new kernel. You can run:

+
+uname -a
+
+
+
+

FFMPEG H264 Android

Convert a video to MP4 compatible with Android / Iphone:

+
+ffmpeg -i inputfilename.ext -aspect 3:2 -s 480x320 -vcodec h264 -b 480k -r 23.976 -acodec aac -ab 96k -sameq -pass 1 outputfilename.mp4
+Here is the command for a 4:3 aspect ratio video.
+ffmpeg -i inputfilename.ext -aspect 3:2 -s 400x300 -vcodec h264 -b 480k -r 23.976 -acodec aac -ab 96k -padtop 10 -padbottom 10 -padleft 40 -padright 40 -sameq -pass 1 outputfilename.mp4
+And here is the command for a 16:9 aspect ratio video.
+ffmpeg -i inputfilename.ext -aspect 3:2 -s 480x270 -vcodec h264 -b 480k -r 23.976 -acodec aac -ab 96k -padtop 24 -padbottom 26 -sameq -pass 1 outputfilename.mp4
+
+

Extracting all frames from a video file is easily achieved with FFmpeg.

+

Here's a simple command line that will create 25 PNG images from every second of footage in the input DV file. The images will be saved in the current directory.:

+
+ffmpeg -i input.dv -r 25 -f image2 images%05d.png
+
+

The newly created files will all start with the word "images" and be numbered consecutively, including five pre-appended zeros. e.g. images000001.png.

+

From a video that was 104 seconds long, for a random example, this command would create 2600 PNG files! Quite messy in the current directory, so instead use this command to save the files in a sub-directory called extracted_images:

+
+ffmpeg -i input.dv -r 25 -f image2 extracted_images/images%05d.png
+
+

Moving on, let's say you just wanted 25 frames from the first 1 second, then this line will work:

+
+ffmpeg -i input.dv -r 25 -t 00:00:01 -f image2 images%05d.png
+
+

The -t flag in FFmpeg specifies the length of time to transcode. This can either be in whole seconds or hh:mm:ss format.

+

Making things a little more complex we can create images from all frames, beginning at the tenth second, and continuing for 5 seconds, with this line:

+
+ffmpeg -i input.dv -r 25 -ss 00:00:10 -t 00:00:05 -f image2 images%05d.png
+
+

The -ss flag is used to denote start position, again in whole seconds or hh:mm:ss format.

+

Maybe extracting an image from every single frame in a video, resulting in a large number of output files, is not what you need. Here's how to create a single indicative poster frame, of the video clip, from the first second of footage:

+
+ffmpeg -i input.dv -r 1  -t 00:00:01 -f image2 images%05d.png
+
+

Notice that the -r flag is now set to 1.

+

If you want the poster frame from a different part of the clip, then specify which second to take it from using the -ss tag, in conjunction with the line above.

+

Lastly, if you wanted to create a thumbnail story board, showing action throughout the entire length of the video clip, you'll need to specify the output image dimensions. Use the following line:

+
+ffmpeg -i input.dv -r 1 -f image2 -s 120x96 images%05d.png
+
+

My original file was 720x576, so the image dimensions are a whole division of this.
