$ lsmod . . Bus 001 Device 004: ID 0ac8:3420 Z-Star Microelectronics Corp. Venus USB2.0 CameraThe device is supported by UVC driver.
ls /dev/vid* /dev/video0So, we have '/dev/video0' as our webcam.
Let's install some required packages.
On a RPi, I have faced multiple issues trying to install packages without first upgrading the system to the latest state. So, let's upgrade the system first.
$ sudo apt-get update && sudo apt-get upgradeAnd, some requirements for MJPEG-Streamer
$ sudo apt-get install subversion imagemagick libjpeg8-devNow, let's download the latest source
$ svn co https://svn.code.sf.net/p/mjpg-streamer/code/mjpg-streamer/ mjpg-streamer $ makeWhen it finishes, it leaves "mjpeg-streamer" binary to the folder. This may be added to path variable. Now, let's stream. 15fps with hardware MJPEG Compression
$ ./mjpg_streamer -i "./input_uvc.so -d /dev/video0 -f 15 " -o "./output_http.so -w ./www"If you get the error like this:
The input device does not supports MJPEG mode You may also try the YUV mode (-yuv option), but it requires a much more CPU power Init v4L2 failed !! exit fatal i: init_VideoIn failedThen we need to add '-y' argument to fallback to software mode.
$ ./mjpg_streamer -i "./input_uvc.so -d /dev/video0 -y -f 15" -o "./output_http.so -w ./www"You can access the web interface at http://<ip>:8080/ where 'ip' is the IP of the Raspberry Pi server. The frame rate can also be changed by specifying the custom value instead of 15. To stream at different resolution with 30fps:
$ ./mjpg_streamer -i "./input_uvc.so -d /dev/video0 -f 15 -r 960x720" -o "./output_http.so -w ./www"The best part of MJPEG-Streamer is that you can also use VLC or any other streaming player to watch the stream and you are not limited to a web interface.
