I've solved my problem reading this article: http://www.jedi.be/blog/2010/08/30/capturing-the-screen-of-your-virtual- machines-using-x-vnc-rdp-or-native/ which basically says that I lacked some libraries (libx11-dev, libxfixes- dev and libxext-dev), and after installing those, I've had x11_grab_device in the list of input devices. -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/821> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker

#1523(undetermined:new): automatic set a default -slices value for ffv1 version 3
by FFmpeg 15 Jul '12

#1523: automatic set a default -slices value for ffv1 version 3 -------------------------------------+------------------------------------- Reporter: dericed | Type: Status: new | enhancement Component: | Priority: normal undetermined | Version: git- Keywords: | master ffv1,threads | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: If I encode to ffv1 version 3 without specifying a -slices value, then slices defaults to zero, which is not allowed, and thus the command fails. Because of this encoding with ffv1 version 3 does not seem to be possible without explicitly stating the slice count. I think most users may not be so picky about slice count and would accept a default value if they do not specify it. Can ffv1 version 3 default to a value for -slices based on detection number of (available) CPU cores.
