$ sudo /etc/init.d/fcinit restart
$ sudo /etc/init.d/webcamstudio start

Draft mode

[tty2] $ startx -- :1.0

Change DISPLAY :1.0 resolution to 640x480

$ xrandr -d :1.0 -s 640x480

Grab DISPLAY :1.0 and send to vloopback

$ ffmpeg -f x11grab -s 640x480 -r 5 \
  -i :1.0 -pix_fmt yuv420p -s 320x240 -r 5 -f yuv4mpegpipe -an - | \
  mjpegtools_yuv_to_v4l /dev/video2

Initial situation

Start grabbing DISPLAY :1.0 to fill USTREAM stream.

LVDS1 primary left, VGA1 (640x480) right at DISPLAY :0.0

chvt N (ttyN with DISPLAY :1.0) and xrandr --same-as (man xrandr)

sleep

$ ./cineforiano.sh

xrandr VGA1 --right-of LVDS1 (man xrandr again :) and chvt (DISPLAY :0.0)

Webcam/Mic to USTREAM

Clap! Clap!
