rsapivid:
pi@raspberrypi ~ $ raspivid raspivid Camera App v1.3.10 Display camera output to display, and optionally saves an H264 capture at requested bitrate usage: raspivid [options] Image parameter commands -?, --help : This help information -w, --width : Set image width <size>. Default 1920 -h, --height : Set image height <size>. Default 1080 -b, --bitrate : Set bitrate. Use bits per second (e.g. 10MBits/s would be -b 10000000) -o, --output : Output filename <filename> (to write to stdout, use '-o -') -v, --verbose : Output verbose information during run -t, --timeout : Time (in ms) to capture for.
