Alternative to Screenium for Linux and splitting extracting audio from video

Question

On my Mac I use Screenium to record screencast or streaming video. I can then take that and extract the audio from the file if I like. I'm looking for a way to do this on Linux.

I've heard of Screenr, Wink, and gtk- recordmydesktop.

What is the best way to record screencasts and streaming video, and what is the best way to split audio from the file aftwerwards in Linux?

RecordMyDesktop / Instanbul

WinFF, is the GUI frontend to ffmpeg

Answer 2

For capture Xvidcap works well. To pull audio out of that file you can use ffmpeg, like so:

ffmpeg -i capture_vid.mpg -ab 128 -ar 44100 extracted_audio.mp3

For GUI-based audio extraction, you can use VLC and the Convert/Stream feature
