You are being very secretive, aren't you? It's much easier to analyze
what you may have done wrong if you show us what you actually did.
Usually, we require the command line you used for ffmpeg and the full,
uncut console output.

And if you had sent us your console output, we would or perhaps
wouldn't have seen a warning issued by ffmpeg. Mine seems to convert to
yuv420p automatically, but I just blindly tried with testsrc,format
(If that warning doesn't exist - it does for H.264 encoding - it might
be worth considering.)
