How to convert .avi to .mp4/.3gp

https://help.ubuntu.com/community/iPodVideoEncoding

I'm guessing its for an iPod thing...

thanks, but this is a large tutorial of many softwares. which should I use.
 I have also tried Arista Transcoder. its great . but can I make preset for my mobile. plz tell me how to creat preset for my device

Try:

sudo apt-get install install lsdvd mplayer gpac zenity mencoder; wget http://diveintomark.org/public/2007/06/podencoder.txt -O /usr/local/bin/ipodencoder; chmod +x ./ipodencoder; sudo mv ./podencoder /usr/bin

You can now use:

ipodencoder mediafile

and it will convert. If you had a decent device it would just play what you have.

thanks a lot @ actionparsnip
I did as you said and the output is

swagatak@MOON:~$ sudo apt-get install install lsdvd mplayer gpac zenity mencoder; wget http://diveintomark.org/public/2007/06/podencoder.txt -O /usr/local/bin/ipodencoder; chmod +x ./ipodencoder; sudo mv ./podencoder /usr/bin

swagatak@MOON:~$

thanks

Sorry:

sudo chmod +x /usr/local/bin/ipodencoder

ipodencoder mediafile was an EXAMPLE

you use your file you want to convert.

thanks @actionparsnip

I run in the terminal
sudo chmod +x /usr/local/bin/ipodencoder
it asked my sudo password and the output is

swagatak@MOON:~$ sudo chmod +x /usr/local/bin/ipodencoder
chmod: cannot access `/usr/local/bin/ipodencoder': No such file or directory
swagatak@MOON:~$

ok run:

cd ~
wget http://diveintomark.org/public/2007/06/podencoder.txt
mv ./podencoder.txt ./ipodencoder
chmod +x ./ipodencoder
sudo mv ./ipodencoder /usr/bin

You can now use the ipodencoder command to make your files into something your ipod can handle (due to its limited abilities)

I dont understand what happened .I run as you said @ actionparsnip
and the output is

swagatak@Moon:~$ cd ~
swagatak@Moon:~$ wget http://diveintomark.org/public/2007/06/podencoder.txt

now what should I do?

thanks

You can now use the ipodencoder command to make your files into something your ipod can handle (due to its limited abilities)

Like I said before.....

so in a terminal you can convert a file named examplefile.avi (for the sake of this example):

ipodencoder examplefile.avi

And it will convert.

thanks @ actionparsnip

I run as you advised,but it is not working. the output is (the name of the song is"Give Me Some Sunshine")

swagatak@Moon:~$ ipodencoder Give Me Some Sunshine.avi
ipodencoder: command not found
swagatak@Moon:~$

Now I want to know, where I have to keep my input file ,which I want to convert and where the output shall I get ?
I want give you the information that I have tried as you said ,keeping the input .avi file in the desktop.

thanks a lot.

Ok and what folder is the file in? Please give the full path (case sensitive)

Thanks

In Linux you need to escape the spaces so interpreter knows the text is part of the filename.

many many thanks @ actionparsnip

I said before the file I have kept in the desktop. the path is /home/swagatak/Desktop

you said
"In Linux you need to escape the spaces so interpreter knows the text is part of the filename."
to do so I have to change my file name ?

No you just change the command. You ran the command in:

/home/swagatak

The file is not in that folder so the command will not have found the file. So in this case you need to run:

cd ~/Desktop
ipodencoder Give\ Me\ Some\ Sunshine.avi

As you can see, you need to use the '\' character to escape the spaces. Spaces in Linux can cause issues but can be managed.

thanks @ actionparsnip

I run

swagatak@Moon:~$ cd ~/Desktop
swagatak@Moon:~/Desktop$ ipodencoder Give\ Me\ Some\ Sunshine.avi
ipodencoder: command not found
swagatak@Moon:~/Desktop$
