Convert .avi into .mp3 on Linux

From time to time I have to google for this, now I am making a post so I know where I can find :)

This converts the complete avi into mp3:

1
ffmpeg -i movieSample.avi -ab 256k -vn autioSample.mp3

This extracts from 00:21:24 for 40s and converts avi into mp3:

1
ffmpeg -ss 00:21:24 -t 00:00:40 -i movieSample.avi -ab 256k -vn autioSample.mp3

jcouchdb – Java5 couchdb driver

jcouchdb [1] is a java5 couchdb driver using the svenson JSON library.

It offers features to support the full range from totally dynamic parsing to parsing into concrete java POJOs, including a mix in between.

jcouchdb is in the early stages of development but there’s a test suite proving that it does at least most of the couchdb operations.

Jcouchdb is released under BSD license.
