text based screen-cast?


I'm looking for software which will allow me to record a screen-cast of a terminal based application, recording keystrokes, timing of keystrokes, and audio.

I see a couple of advantages to this approach over video capture:
  1. Display independence: the viewer can display text in any resolution/style they want, not limited to the resolution of the recorded video.
  2. Ability to copy and paste text from the screencast.

So what you are really looking for is a terminal emulator with a "replay" mode, so that it goes through and replays the exact keystrokes that were recorded previously (though not actually running anything it plays back, as that could have disastrous results).

I guess I can see the advantage of that over a video of somebody entering text into the terminal, though I don't really know how often this happens that it is really a problem. Are there that many Linux terminal video tutorials out there in the first place?

In any event, I have never heard of such an application, and I'm pretty sure it doesn't exist. That said, it seems like it would be easy enough to write one by just modifying an existing terminal application and spinning it off into a recorder/viewer.

I'm actually looking for something that will show terminal output synced with voice, allowing narration of what's being done on the command line. I think that there are some XML standards that allow syncing of multimedia, I'm willing to bet that you could shoehorn a text stream in there somewhere...

I think that I'm basically looking for something like this... except that instead of having a word by word transcription playing on the screen, you would see source code, or shell commands on the screen.

I'm marking this thread as solved, based on the link in the previous post... I don't think that there's a capture utility out there per se, but it's obvious that the technology exists to make this happen (and I'm going to see if I can't talk to the programmer who put the html5 demo together).

I know the thread's marked solved already, but I was curious to see what was suggested as a solution.
I'm wondering if the script command might be close to what you're looking for, though I'm not sure it does audio. Unless the audio happens as control codes maybe. Might be worth a look anyway, there's a description of it here:
http://linux.byexamples.com/archives...-replay-later/
and various other places. I suggest using 'scriptreplay' when doing a Google search as using 'script' will throw up all sorts of things!
On the SuSE machine I'm looking on the script and scriptreplay commands are part of the util-linux package.

I didn't investigate 'script' and 'scriptreplay' until 'script' came up on commandlinefu yesterday.

Based on that, I added this entry on commandlinefu.com... it launches arecord and script at the same time.

Thanks for pointing me in that direction, even if I was being dense and didn't follow the tip until I about stepped on it.
