Monitor stream of a webcam

[appost]

Hi all, I installed Zoneminder 1.28 on Ubuntu server, it works good with IP cameras and it is a very good software.
Instead I have problems to add a stream of a laptop's webcam. I don't find what is wrong:
I send the stream with vlc:

Code: Select all

Port 8080
Path /
Activate trasconding disabled
encapsulation: mjpeg
only video enabled
result: :sout=#http{mux=mpjpeg,dst=:8080/} :sout-keep

on ZoneMinder console:

Code: Select all

Source Type: Remote
Function: Monitor
Remote Protocol: HTTP
Remote Host Name: 192.168.122.1 (the Ubuntu server is a virtual machine of the host which is Debian, the host is the laptop with the webcam)
Remote Host Port 8080
Remote Host Path /

I obtain only a blue screen with timestamp

Any idea?

sorry about the problem isn't zoneminder but vlc.
Anyway I will post the solution if I solve it

There are some "extra" packages you need to install to use libvlc. See the easy how to in the WIKI for Ubuntu. Some of us have also had issues with libvlc locking up or delaying images.

Thank you bbunge,
the problem is on the host (Debian testing), to be sure I installed anyway the packages libvlc-dev libvlccore-dev as in the wiki, but the problem remains the same.
EDIT:
The correct command is:

Code: Select all

 cvlc -vvv v4l2:///dev/video0 --sout '#http{mux=avi,dst=:8080/}'

but I still get the blue screen with timestamp

ok, I generated the stream with vlc with these options:

Code: Select all

:sout=#transcode{vcodec=MJPG,vb=800,fps=1,scale=Auto,acodec=none}:http{mux=mpjpeg,dst=:8080/} :sout-keep

and I get the blue screen with this informantion in the log:

Code: Select all
