Convert a VCD (avesqrt.dat) file into mp3 format

There is an easy way to convert VCD (Video CD) file into MP3. What you need are just MPlayer and Lame. MPlayer is used to convert the VCD file to WAV by using the PCM audio output, and then you can convert the WAV file to MP3 by using Lame.

First, you have to convert it to WAV by using the command:

$ mplayer -ao pcm /path/to/vcd/avseq01.dat 

MPlayer will play the VCD file like usual, but with no sound. Just wait until it finished. You'll get a file 'audiodump.wav' that you can convert to MP3 by using the command:

$ lame -h audiodump.wav newfile.mp3

Switch -h is used to get high quality MP3 file, but bigger filesize.
