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

[Roger Berk]

It almost works with the following, but it produces an error complaining about no input file....
This produces an empty test.mpg..... 

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

File 'test.mpg' already exists. Overwrite ? [y/N] y
At least one input file must be specified

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 ?
