Sorry guys to disturb you with like this but I'm stuck


I have to 4 usb webcam stream (from 4 different machine)  embed to a website

I read and try adobe flash media server (and it likes to work on linux ) but
unfortunately the encoder witch "stream" the webcam to the server is
available only windows :(  (of course no linux version yet someone use wine
to use but I think this is not the best solution )

I looked for any alternatives I found red5 and an article about how to use
the local flashplayer plugin publish the cam ( http://ptm.fi/?p=29 ,
http://ptm.fi/?cat=6 ) but I dont really know how to start

Is it worth to try usb-server to use remote cams as local device?

If anybody had experiences about like my problem please help my to give
some  info and manual link

of course I don't insist the adobe product and solution I just want to work
:)

thanks your time and help

have a nice day

Z.

I may have misunderstood your question.

Last summer I was looking to stream my webcam to flash.  I think I
looked at the red5 product but decided against it.  There's also some
web services that will do it but I didn't want my webcam hosted on
another service.

So I ended up using a vlc script.  vlc is cool because not only can you
stream to flv but just about any other format.

script will look something like this:

WIDTH=320
HEIGHT=240
BITRATE=512
BITRATE=1024
CODEC1=FLV1
AUDIODEV="/dev/dsp1"
DEV="/dev/video2"

vlc  \
    -I dummy \
    v4l2://${DEV}:width=${WIDTH}:height=${HEIGHT} \
    :input-slave=oss://${AUDIODEV} \
    --sub-filter time \
    --sout \
'#transcode{vcodec='${CODEC1}',vb='${BITRATE}',acodec=mp3,samplerate=11025}:std{access=http,dst=127.0.0.1:8082/stream.flv}}

I'm not sure this is what you are looking for, but
'zoneminder' is very cool, although I'm not sure it
works with mp4 containers. You have to research the 
encoding format details.


h.264 is very bandwidth efficient, but requires relatively
large processing resources to encode, but requires
relatively light processing resources to decode.


PS, the VLC solution the other guys have mentioned looks
very doable on a web-server.....


hth,
James

cool for observing home things and more

yes the h.264 codec is very usable and vlc looks can serve my  web-streaming
(yes the main problem is find the right the bandwith and the CPU and memory
usage)

have a nice day and thanks your time and help
