Best practise for recording videotutorials?
 
Im not quite sure what forum to post this in.. please move to appropriate..

I am planning to do some video tutorials and app reviews on the N900 (and N8x0).. Is there a way to record the screen without just filming the device?

Would it work to install a VNC-server on the n900 and then vnc to it?

Please post suggestions..

Using the following GStreamer pipe (taken from Istanbul) works in the SDK, with Xephyr running as display :2.0:
Code:
gst-launch-0.10 ximagesrc name=videosource display-name=:2.0 screen-num=0 startx=0 starty=0 endx=799 endy=479 use-damage=false show-pointer=false ! video/x-raw-rgb,framerate=24/1 ! videorate ! ffmpegcolorspace ! videoscale method=1 ! video/x-raw-yuv,width=800,height=480,framerate=24/1 ! theoraenc ! oggmux name=mux ! filesink location=test.ogg
I guess on the device you'd want to use the DSP h264 encoder and mpeg4 muxer instead.

You mean that would work on the device also ?

The snag you may run into on certain apps is that there are sometimes no on-screen cues to indicate where you've selected something.

So for example if you need to tap an icon but the icon doesn't change when you tap it, a direct video won't show how the action was taken.

Mm, I can see that problem. I can add something for that I suppose (abit of work) in post production as long as I remember where I pressed..

Looking forward in testing this..

Check http://maemo.org/downloads/product/Maemo5/load-applet/

It has currently a bug preventing proper video recording but hopefully it's fixed but the time the N900 is in the shops.

could you use vnc and a PC based screen recorder?

Actually, it would be neat to have an app that records the screen and also shows keypresses in the corner of the video and taps on the screen. I wish I had the time to make this, but it's a thought for a motivated party.

That was my first idea there too. I do not know if vnc server works on the N900 yet.
