Screencast

I am trying to capture screencast for showing grandchildren how to play and some escapades. I am using Ubuntu 12.04. I've tried vlc, and recordmydesktop. Both start off OK, but all I get is a black screen for the duration of the recording - the opening screen shows, but once it goes to full screen, nothing but black!

I would really appreciate some assistance with this please.

I've just added BGS and some other updated OXPs - it has made a great improvement with background noises and a changed screen when docked. Thanks to all the authors, debuggers involved.

Take a look at this - this is how I do mine.

Edited to correct link to 'SmivsTV'.

Thanks Smivs.. I've had some success using Kazam Screencaster to record Oolite on Linux Mint, but no joy on the audio side, unfortunately. I followed the instructions at the link you provided, and have spent a couple of hours or so recompiling the libraries and FFmpeg. Now to start playing with it and see how things go! 8)

I'm not sure why you couldn't see the link.. here is a direct link (start with the second post):
http://ubuntuforums.org/showthread.php?t=1392026

The article also has a lot of examples and explanations of how to use and get the most out of ffmpeg.

The article links to a page detailing how to recompile the libraries and ffmpeg. You'll need to do this to get things to work properly. On my old AMD Athlon 1.1GHz machine it took around 2 hours to compile everything.

Edit: Oops.. I guess you meant you can't see the 'mine'.. Smivs, your second link doesn't link to anything!

Well I tried Istanbul and ffmpeg - let's just say the results didn't leave much to be desired :(. I wish you luck Ozhank - this seems to be a bit of a trick to get to work properly.

Ha, updated the link to 'SmivsTV' in my post above to one that should work.
The only problem I've had using ffmpeg and the method outlined in the article I linked to is that the audio goes out of synch a bit, and this is quite noticeable on longer recordings - the audio lags behind the corresponding video. I currently overcome this by editing the audio track, which is a time-consuming affair. If anybody knows a way to keep the audio in synch I'd be very interested to learn how to do this.

Gahh! I should have said Kazam Screencaster, not Istanbul.. (that's what comes of having a whole bunch of desktop recording apps installed for testing) sorry! :oops:

I know the feeling! I have such ridiculous amount of disk space on my Mint partition that I have pretty well installed every app that seemed even remotely interesting :D.

Thanks to all the suggestions, I can now get a screencast, but no sound (working on this), but not at full screen mode, only in window mode, so all my Unity icons etc show. But I am working on it.

I've installed the new BGS.oxp - huge improvement to the look of Oolite.

Curious as to whether you got this working or not. I haven't had much luck with it, but with all the eye candy, settings, a little hyper radio for ambiance, and I could really make some good videos :mrgreen:,
