Ripping VCD to Various Formats


Using VCDXRIP

To convert to MPEG:

$ vcdxrip


USING MENCODER

mencoder [options] file [file|URL|-] [-o file | file://file | smb://[user:pass@]host/filepath]

mencoder vcd//:2 -oac lavc -ovc lavc -o filename.avi 

($ sign is the terminal prompt)


                 -oac lavc
                      Encode with a libavcodec codec

                 -ovc lavc
                      Encode with a libavcodec codec.




Using CDFS

The source can be downloaded here:

http://users.elis.ugent.be/~mronsse/cdfs/download/

(Unfortunately, the driver doesn't yet support later Linux versions).

$ mount -t cdfs -o ro /dev/cdrom /mnt/video

And copy the *.DAT files



FFMPEG

FFMPEG is a very powerful tool (command-line) to transcode media file.

For example, to extract audio from an AVI file:

$ ffmeg -i source_video.avi -vn -ar 44100 -ac 2 192 -f mp3 sound.mp3

To convert MPG to AVI (or vise-versa):

$ ffmeg -i video_original.mpg output.avi

To encode WAV to mp3:

$ ffmpeg -i video.wav -vn -ar 44100 -ac 2 -ab 192 -f mp3 song.mp3


To mix a WAV file with a video file:

$ ffmpeg -i audio.wav -i video.avi audio_video.avi

To convert AVI to MPEG suitable for DVD:

ffmpeg -i source_video.avi -target pal-dvd -ps 2000000000 -aspect 16:9 finale_video.mpeg 


AVI to VCD:

$ ffmpeg -i video.avi -target ntsc-vcd video_out.mpg

To use 2-pass encoding, pass "-pass 2 -passlogfile somefile" before output file.

HandBrake


We then can use Handbrake to transcode video from CD/DVD to various formats, especially for Apple products.
There are two versions of HandBrake, one is the GUI front-end, and the CLI version.


To list the built-in presets:

$ HandBrakeCLI -z

To use the preset, use capital "-Z"
For example:

$HandBrakeCLI -Z "iPhone 4" -i avseq0.avi -o output.mp4
