Under the operating systems I know, '>' is the "redirect stdout to
file" operator. To direct the stdout to another program's stdin, you
would need to '|' (pipe) operator.

You would be overwriting ffmpeg.exe in this case. I wonder why Windows
actually manages to execute ffmpeg at all.

We usually like to see the complete, uncut console output. In this
case, ffmpeg is probably just waiting for something to appear on stdin,
which isn't happening (see above).

If that's your doubt, you would use ffmpeg with dummy data (anoisesrc,
for example) and see whether that works, to rule out the Java+stdin
part.
