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

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

Convert .ogg to .mp3

for x in *.ogg; do ffmpeg -i "$x" -ab 128 "`basename "$x" .ogg`.mp3"; done

This does an entire dir at once. You must be inside the dir you want to convert. Substitute whatever you want your target bitrate to be up where 128 is.
