Create Flash video from DVD (DVD to FLV) with Ubuntu
All the steps below are valid for any Linux, not just Debian and Ubuntu. Simply use your distro’s package manager (YaST, Yum, Rpm, etc.) to install the necessary packages. Creating a flash video from a DVD will allow you to post it on Youtube or on your website.
1. Make sure that you have mencoder installed. Mencoder is Mplayer’s movie encoder and it can convert multiple video and audio formats.
If you have not yet installed it, do it now:
sudo apt-get install mencoder
This will install 4 packages: libfaac0 libmp3lame0 libx264-65 libxvidcore4 mencoder.
2. Run the command to convert the DVD file to FLV. This is a sample command, you will have to change the paths to the input and output files if necessary. In this case the input file is: /media/cdrom0/VIDEO_TS/VTS_01_1.VOB and the output file is video.flv, which is specified after the “-o” option:
mencoder /media/cdrom0/VIDEO_TS/VTS_01_1.VOB -o video.flv -of lavf -ovc lavc -oac mp3lame -lavcopts vcodec=flv:vbitrate=500:autoaspect:mbd=2:mv0:trell:v4mv:cbp:last_pred=3:predia=2:dia=2:precmp=2:cmp=2:subcmp=2:preme=2:turbo:acodec=mp3:abitrate=56 -vf scale=320:240 -srate 22050 -af lavcresample=22050
As you can see, mencoder has a lot of options and you can control just about everything. Check out the man pages for mencoder for more information.
