 I've tried configuring ffmpeg with --enable-x11grab and the configure
 passed without any errors, but x11 input wasn't enabled (I still had the
 message "Unknown input format: 'x11grab'" after the building process and
 even ./configure --enable-x11grab .. | grep x11_grab_device didn't produce
 any output)

 Recommendation is that configure should check if needed libraries are
 installed for x11 input device to be properly built and if they are not
 installed, to break out of the configure process with a descriptive error
 message.

 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.
