[FFmpeg-user] Command line to create mpeg ( or anything ) from testsrc

C:\bin>ffmpeg -i testsrc=duration=10:size=1280x720:rate=30 -vcodec mpeg2video test.mpg

produces the error:

testsrc=duration=10:size=1280x720:rate=30: No such file or directory

I have tried many other combinations, with various errors.

Any Ideas ?
