Thanks for reply Carl Eugen!
(This is the 3 email, first was to large for squirrelmail, second was too
large for mailing system, "awaiting approval" :)
I use a "one-row" shell script for invocation of ffmpeg:

#! /bin/sh
#
# openRTSP -u tovis tovis -vm -b 1000000 rtsp://172.16.3.2/mjpeg
>$SLICE1_FILE 2>/dev/null &
#
# ffmpeg -i rtsp://tovis:tovis@172.16.3.2/mjpeg -an clip.mjpeg
ffmpeg -v verbose -i rtsp://tovis:tovis@172.16.3.2/mjpeg -an -vcodec copy
clip.mjpeg

There is an old command for openRTSP which I have used earlier, it is
work, good for lookup.

Output file #0 does not contain any stream

Messages not so much informative for me, seem to be ffmpeg does not

Any suggestion?
