Sat Feb 05, 2011 8:48 am
with recordmydesktop i can't :D move layers ...

so i was a bit frustrated

well i found a solutions


(huge files..)

ffmpeg -f alsa -ac 2 -ar 48000 -i hw:0,0 -s 1280x800 -f x11grab -r 30 -i :0.0 -acodec pcm_s16le -vcodec ljpeg output.mkv


or this one (pulse and x264 )

ffmpeg -f alsa -ac 2 -ar 48000 -i pulse -f x11grab -r 30 -s 1024×768 -i :0.0 -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 output.mkv

For some reason, I've always found recordmydesktop works *much* better if you skip *any* gui and just type recordmydesktop at the terminal. That records the while thing at 15fps(?) and saves it as out.ogv to your home folder. There is a really nice option though to skip every x frames so you can record a timelapse without taking much disk space / cpu (or was that FFMPEG?)

Nice. Looking forward to seeing what you create. We could definitely use some more timelapse speed painting vids for Krita. :D

The solution is in the recordmydesktop faqs:

"When recording, some windows don't receive drag'n drop events.

There are some occassions where recordMyDesktop seems to interfere with dragging and dropping.
Disabling the frame will probably resolve any such problems. To do this on the commandline,
use the --no-frame option, while for the graphical frontends, consult this page
(uncheck the Outline Capture Area On Screen checkbox, in Advanced => Misc.)."

:) Well i have just compiled ffmpeg locally with every codecs and...

ffmpeg -f alsa -ac 2 -ar 48000 -i hw:0,0 -s 1280x800 -f x11grab -r 30 -i :0.0 -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 2 output.mkv


works much more better than recordmydesktop try it :P
ffmpeg is so powerfull... who cares about recordmydesktop anymore?
