Let's set up raspivid so that, as it runs in the background, we can simply send a message to the process to stop or start video acquisition. This setup can also work for taking snapshot still images with raspistill too.
The script we will create allows you to easily control rapsivid from the command line. The command line in the script that instantiates the raspivid process looks like this:
sudo raspivid -w 800 -h 600 -i pause -n -o /media/data/video/test%03d.h264 -sg 10000 -s -t 0 &

This sets the height and width of the captured image. |
