Need a screencast capturing solution, fast!
 
Hey members,
I want to take a screencast from my N900, you know, "videoy" screenshots, load-applet honestly fails at doing that. Is there any streaming solution which streams video from my N900's screen rather than its camera(s)?

Holy crap!!! Is this legit?? That would be amazing to have the video capture from the load applet working correctly!!


Has anyone tried it? Not sure how safe I feel about installing a load applet replacement when I'm not ready for a re-flash should it go south.

Did not work at all :(
I mean, when I tap the webcam icon, it changes to blue "tapped" but then when I "turn it off" nothing is recorded, .videos is empty...
Is it me? Or is this a fake?

Stand back bros, I got this one...


Code:

ffmpeg -f x11grab -s wxga -r 25 -i :0.0 -sameq /tmp/out.mpg
Quote:

A pure coincidence, I have done so much video processing with ffmpeg that I know what most of this command does without looking much in the manual.

The ffmpeg generally can be descibed as a command that takes a bunch of options and the last option is the output file. In this case the options are -f x11grab -s wxga -r 25 -i :0.0 -sameq and the output file is /tmp/out.mpg.

Here is what the options mean:

* -f x11grab makes ffmpeg to set the input video format as x11grab. The X11 framebuffer has a specific format it presents data in and it makes ffmpeg to decode it correctly.
* -s wxga makes ffmpeg to set the size of the video to wxga which is shortcut for 1366x768. This is a strange resolution to use, I'd just write -s 800x600.
* -r 25 sets the framerate of the video to 25fps.
* -i :0.0 sets the video input file to X11 display 0.0 at localhost.
* -sameq preserves the quality of input stream. It's best to preserve the quality and post-process it later.

You can also specify ffmpeg to grab display from another x-server by changing the -i :0.0 to -i host:0.0.

sorry, buddy i dunno. I just did what it says on that mumbo-jumbo site, except for APT-GET -F INSTALL. I skipped that part and everything works.
