[FFmpeg-user] ffmpeg on Ubuntu 12.04 to Wowza server.

[Leonard Bogard]

After finally getting ffmpeg to compile I've been trying for about 2 days
to get ffmpeg to live stream from my DeckLink Mini Recorder card (capture
device) to a WoWza server using rtmp.  Everytime I start ffmpeg I ALWAYS
get this line "Could not write header for output file #0 (incorrect codec
parameters ?): Operation not permitted" and then ffmpeg terminates.

FMLE seems to work fine (even to my local test trial install of WoWza) on
my old and overburdoned Windows XP machine

I'm running a brand new install of Ubuntu 12.04 Server amd64 on a brand
(butt-spanking) new PC.

This is the command I'm issuing (and the response):

OUTSTREAM="-f mp4 rtmp://192.168.7.2:1935/live/kcfstream.mp4"

  $OUTSTREAM

Can somebody tell me what I'm doing wrong?
