What's a good program to record videos or screencasts being played on screen?
回答1:
I've had success with Camtasia / CamStudio. Check out http://showmedo.com for tutorials. It's a little recursive though - it would be better to capture it from source.

On Windows, you have CamTasia (commercial), CamStudio (GPL), FRAPS (commercial with free trial).
FRAPS will definitely do your job, it was designed to capture videos of 3D games. CamTasia might, it has a low-level custom codec (TechSmith Capture Codec). CamStudio probably won't, at least not smoothly. CamStudio has issues on Vista, I don't know about FRAPS, CamTasia is fine on Vista.
On the Mac try ScreenFlow, their example video makes it clear it can capture live video streams.
On Linux you'll be in a bit of trouble. If you recompile ffmpeg you might get it recording video. I think recordmydesktop won't do the job.

If you're using Vista the latest version of Fraps might also do what you need. I haven't tried it for that, though, just games

DemoCreator could be an good option. It is easy to use, and there are powerful editing features with it.
