Mjpeg Streamer

Thu Jan 22, 2015 9:58 pm

Hello!

When I installed Mjpeg-Streamer and start the streamer I get the error message below.
I'm using a Pi Noir camera (the one with the cable directly to the Raspberry B+).

What I would like to do is stream the camera to a website to see it remotely.
What is going wrong? With other things (VLC stream or Raspistill) the camera is working fine.
So the camera works.
So just get the stream with a simple thing on the web, thats all I need..

MJPG Streamer Version: svn rev: Unversioned directory
i: Using V4L2 device.: /dev/video0
i: Desired Resolution: 640 x 480
i: Frames Per Second.: 5
i: Format............: MJPEG
ERROR opening V4L interface: No such file or directory
Init v4L2 failed !! exit fatal
i: init_VideoIn failed

Code: Select all

sudo modprobe bcm2835-v4l2
The V4L2 driver isn't loaded by default. Raspistill doesn't use V4L2 hence no errors. Don't know about VLC.

How did you install mjpeg Streamer?

Code: Select all

sudo apt-get install subversion libjpeg8-dev \
imagemagick libv4l-0 libv4l-dev
cd ~
svn co https://svn.code.sf.net/p/mjpg-streamer/code mjpg-streamer
cd mjpg-streamer/mjpg-streamer
make USE_LIBV4L2=true clean all
sudo make install

That is the trick! Just load the driver with sudo modprobe bcm2835-v4l2 !
Thanks!
When I now load the driver, Motioneye is detecting the camera automatically.

R-PI with rpi camera has blank image, though raspistill gets a nice image,
on the other hand on a USB camera works fine.
