Hi

I am having trouble configuring ffserver + ffmpeg to do a live stream from a 
bktr capture card.  The same setup use to work with freeBSD 5.3 and ffmpeg 
ffmpeg-0.4.8, but I cannot get it running since I upgraded to 5.4.

Problem with ffmpeg-0.4.9
I can start ffserver (using the default ffserver.conf file)

As soon as I start ffmpeg 
(ffmpeg -ad /dev/dsp0.0 -vd /dev/bktr0 http://localhost:8090/feed1.ffm)
 then ffserver will write "Floating exception" and do core dump.
ffmpeg will write:
Could not read stream parameters from 'http://localhost:8090/feed1.ffm'

Problem with ffmpeg-devel-0.4.9.c.20050528
ffserver works file, but ffmpeg gives the following message:

ffmpeg -ad /dev/dsp0.1 -vd /dev/bktr0 http://localhost:80/feed1.ffm
ffmpeg version 0.4.9-pre1, build 4755, Copyright (c) 2000-2004 Fabrice Bellard

  built on May 29 2005 21:01:46, gcc: 3.4.2 [FreeBSD] 20040728
Could not find video grab device

I also see from the Makefile:
# video captuure is not working as of yet
WITH_VIDEO_CAPTURE=no

Does this mean that ffmpeg-devel does not support live video streaming ?

Regards
Johann
