Or quote the whole pipeline argument to gst-launch:

gst-launch -v 'v4l2src always-copy=FALSE num-buffers=800 input-src=composite ! video/x-raw-yuv, format=(fourcc)NV12, width=720, height=480 ! TIVidenc1 codecName=h264enc engineName=codecServer ! filesink location=/home/gr8.264'

(Note the single quote before v4l2src and after gr8.264.)

Assuming the shell you are using is "bash", the meaning of (unquoted) parentheses is:
