Hello,
I would like to use ffmpeg and ffserver to stream to a flash player using
the way explained in :
http://ubuntuforums.org/archive/index.php/t-665607.html
So here is my ffserver.conf :
---------------------------------------------------------
Port 8090
BindAddress 0.0.0.0
MaxHTTPConnections 2000
MaxClients 1000
MaxBandwidth 1000

</Feed>
<Stream test.flv>

</Stream>

</Stream>

----------------------- END OF ffserver.conf -------------------------------
I run ffserver as root, and there is no error message, all seems to be OK.

Tue Mar 30 18:12:34 2010 FFserver started.
-------------------- END OF ffserver output ----------------------------
Then, I run ffmpeg with the following command line (as root) :
sudo ./ffmpeg -r 15 -s 320x240 -f video4linux2 -i /dev/video1 -f flv -r 15
http://127.0.0.1:8090/feed1.ffm
As soon as ffmpeg is running, I have got the following message in the
ffserver's shell :
------------------- BEGINING OF ffserver output ----------------------------

-------------------- END OF ffserver output ----------------------------
All seems ok... but, there are two different errors when I run ffmpeg (in
the ffmpeg's console):
ERROR A :
===========
Some times, ffmpeg write it :

What is this negative time stamp ??? I try to force timestamp help to the
option -timestamp XX, but result become "invalid time stamp XX" !
But if I try to re-run my ffmpeg command two or three times, this error
disappear, and the problem will be "the error B" described as follow.
ERROR B :
=========
I try to run ffmpeg with the following command line :
a...@hp1:~/Sources/ffmpeg-0.5.1$ sudo ./ffmpeg -r 15 -s 320x240 -f

And nothing more happens....
I read somewhere that this error message seems that ffmpeg can't open the
destination file (http://127.0.0.1:8090/feed1.ffm)
So here is my question : What am I doing wrong ???
