Screencasts from Linux

Filed under: Video — cygnl7 @ 11:43 pm

Looking into ways to do screencasts from Linux I tried Wink, Istanbul, and Recordmydesktop. My requirements were that I could record both video and audio within the same tool. Wink 2.0 isn’t released for Linux yet and it’s the first version to support recording sounds, Istanbul tried to record but didn’t save the sound (and never really wrote the entire file out), but Recordmydesktop did it’s thing beautifully.

I’m still in the middle of the transcode from the ATSC broadcast mpeg encoding (which I’m not sure what it is, but I haven’t really looked into it) to VOB mpeg2 so I can write a show I recorded to DVD. But so far it seems to be working well. I tried all sorts of windows tools, and I’m thinking I could have gotten avisynth to work, but it was much simpler to use ffmpeg to fix it up. ffmpeg didn’t work so well. Update below.
