Motion versión MMAL

La versión oficial de los repositorios por defecto no funciona, pero un tal Dozencrows ha realizado un binario que funciona perfecto en la raspberry.

Lo unico que la instalación es diferente, primero es recomendable instalar la versión oficial, ya que esta instala todas las dependecias.

Descargamos la versión modificada

wget https://www.dropbox.com/s/xdfcxm5hu71s97d/motion-mmal.tar.gz

wget http://captain-slow.dk/motion/motion-mmal.tar.gz

tar zxvf motion-mmal.tar.gz
sudo mv motion /usr/bin/motion
sudo mv motion-mmalcam.conf /etc/motion.conf

# Minimum time in seconds between capturing picture frames from the camera.
# Default: 0 = disabled - the capture rate is given by the camera framerate.
# This option is used when you want to capture images at a rate lower than 2 per second.
minimum_frame_time 5

# Specifies the number of pre-captured (buffered) pictures from before motion
# was detected that will be output at motion detection.
# Recommended range: 0 to 5 (default: 0)
# Do not use large values! Large values will cause Motion to skip video frames and
# cause unsmooth mpegs. To smooth mpegs use larger values of post_capture instead.
