Subject "new error" is a rather ambiguous title. You really should
make that more specific. How are people supposed to know what this is
about when browsing the mailing archive?

I doubt that the documentation says that. Where?
Syntax is important. Options start with a -. And key/value pairs must
be connected by an = sign.

Could you possibly tell us the exact command and error? I, for one,
don't know what is what here.

What is that '.' doing there at the end? That's an error right there.
And there is an '=' missing.

$ ffmpeg -i video.avi -metadata mime_type=application/x-shockwave-flash

That's because of your sloppy syntax ffmpeg mistakes
application/x-shockwave-flash as an output file path.

You understood it wrong.

Once you understand the documentation there is no need. If you have
questions, phrase them, so people understand. And provide the full
output of your commands (without the status line, -nostats). Also,
you should read it first! Most often the messages are quite clear.

And if you reply by quoting everything, again, I am done responding!
Have a look at this mail and get an idea what inline reply means and
how to cut the quotation to the relevant part you are responding to.
