MPD + MPC

These are the two programs of choice when playing and serving large music collections.

I am currently up to almost 9,000 songs and counting.

Mediatomb and UPnP

Puppy linux and Mediatomb Media Server for DLNA and UPnP

The following is for Mediatomb Version 12
I usually create .pets for easy removal if unwanted

autoconf > 2.6 is required
http://ftp.gnu.org/gnu/autoconf/
untar

./configure
make
make install DESTDIR=/root/test/autoconf-2.65

Download Mediatomb:
svn co http://svn.mediatomb.cc/svnroot/mediatomb/trunk/mediatomb mediatomb

cd to mediatomb directory and:
autoreconf -i
./configure
make
make install DESTDIR=/root/test/mediatomb

Install mediatomb.pet
make sure /root/.mediatomb/config.xml points to /usr/local/share/mediashare not /usr/share/mediatomb

in console:
mediatomb

it should tell you which port it's running on.

access with localhost:[port]/ in your browser

For great trancoding tips, see: http://mediatomb.cc/dokuwiki/transcoding:transcoding

webcam screenshots

Using ffmpeg with webcam

take one image per second
-r 1
to take images for 3 seconds
-t 3

so this will give you 3 jpegs in your root directory at vga resolution
Code:

ffmpeg -y -r 1 -t 3 -f video4linux2 -s vga -i /dev/video0 ~/camshot%d.jpeg


similarly here is a cheap way to capture webcam video:

rxvt +sb -bg orange -geometry 80x2 -e ffmpeg -y -f oss -i /dev/audio -f video4linux2 -s qvga -i /dev/video0 ~/a.avi
---------------------------------------

Using mplayer with webcam

changing -frames to different values changes number of screenshots.

mplayer -fps 1 tv:// -tv driver=v4l2:device=/dev/video0:width=320:height=240:outfmt=rgb24 -frames 5 -vo jpeg

Telnet and email

Open a connection from your computer to your mail server.
Code:
telnet mail.domain.ext 110

You should receive a reply like:
Trying ???.???.???.???...
Connected to mail.domain.ext.
Escape character is '^]'.
+OK ready

Then log in:
Code:
USER username

This should give you:
+OK Password required for userName.

Now give your password:
Code:
PASS password

Should yield:
+OK userName has ? visible messages (? hidden) in ????? octets.

To see a list of your emails awaiting collection use the LIST command, this will also show you the id number of your messages (e.g. 1 or 2 etc.)

To view the contents of an email type RETR + the id number of the message (e.g RETR 1).

To delete a message use DELE + the id number of the message (e.g DELE 1).

To leave your mailbox and close the connection use QUIT
