m4v converter (video on new ipod)


Does anyone know of any linux software that will convert mpeg/avi to m4v (quicktime) format?

I just bought a new video ipod and would like to get some movies on there. I have them in mpeg and avi format.

Gtkpod will allow me to put m4v format video clips onto my ipod. Is there any software to convert into m4v, or any software that will put other formats onto the video ipod, thx.

PS: mp3 and cover art sync works perfect in amarok

I use all the vlc packages. I have the followin vlc rpm's (using Mandriva, but they should be similar):

mozilla-plugin-vlc
svlc
vlc
vlc-more-skins
vlc-plugin-a52
vlc-plugin-aa
vlc-plugin-alsa
vlc-plugin-arts
vlc-plugin-dvdnav
vlc-plugin-esd
vlc-plugin-faad
vlc-plugin-flac
vlc-plugin-ggi
vlc-plugin-gnutls
vlc-plugin-lirc
vlc-plugin-mad
vlc-plugin-mod
vlc-plugin-mpc
vlc-plugin-ncurses
vlc-plugin-ogg
vlc-plugin-opengl
vlc-plugin-sdl
vlc-plugin-speex
vlc-plugin-xosd


I thing the -faad plugin is the key one. It is the mp4 plugin. Then I use a script for vlc. to expedite matters:

Code:
#!/bin/bash

base=`echo $1 | gawk -F. '{print $1}' `

echo "$1 $base"

vlc -vvv "$1" :sout="#transcode{vcodec=mp4v,vb=1024,scale=1,acodec=mp4a,ab=128,channels=2}:standard{access=file,url=$base.mp4}"  vlc:quit --aspect-ratio "4:3" --sout-transcode-width 360 --sout-transcode-height 240 --sout-transcode-fps 30
If you convert it to batch file for win32, vlc will also work on windows. Save this to a file called something like ipod.sh, and make it executable.

chmod +x ipod.sh

Then run it like so:

./ipod.sh vidfile.avi

You can also lower the video bit rate a bit if you want to. 1Mb/s is a bit high for such a small screen.

Good luck,
Pete

With all the plugins, just about everything. Now, one thing I found out. If you are transcoding to x264, do not stop the process. If you stop it early, or try to view it prior to finishing, the video is unviewable. You must let the encoder finish.

Cheers,
Pete

sorry if i'm a bit late- but I just swiched to Kubuntu and was able to install vlc.

I tried your script again and it worked- but there is now sound on the output file. Is there any way to fix this? music videos...

Does the original file play fine with vlc? If it does, the decoder is working. I would be safe to assume it is probable the aac encoder.

I would do a simple for loop wrapper. ie
Code:
user@comp>$ for i in *.avi ; do ./ipod.sh $i ; done

It is possible to reverse this process (ie: convert m4v to mpeg or other)?

Have a look at http://thinliquidfilm.org. It's a gui that'll do batch video conversion for the ipod, and upload it as well.
