I know very (very!) little about ffserver. But: Isn't it sufficient to
provide the encoding parameters in the ffserver config file?

We kindly ask you to post the *complete* uncut console output along
with the corresponding ffmpeg command line. All the log information is
valuable.

Do you also get this when it succeeds?
