Webcam doesn't works ?

Hello,

I'm french and i build my first 3D printer, i have chosen repetier server to work on Raspberry Pi 3 and Repetier Firmware on Pibot V2. All works great except the webcam. 
I activated the pro trial version, when i connect the webcam on raspberry, it is detected on video0 and by repetier server. 
I set 320x240 and 15 fps, assign parameters and restart server but it doesn't works.

The repetier server log is:

I used your Raspberry image 0.80.3.

Thanks a lot for your help.

    The problem lies here:

    May 25 17:11:23 RepetierServer startAllCams[3457]: Webcam does not support MJPG - using slower YUYV instead!
    May 25 17:11:23 RepetierServer startAllCams[3457]: Best resolution: 0 x 0 at 0
    May 25 17:11:23 RepetierServer startAllCams[3457]: /usr/local/bin/mjpg_streamer -i "/usr/local/lib/mjpg-streamer/input_uvc.so -d /dev/video0 --fps 0 -q 85 -r 0x0 -y -r 320x240 -f 15" -o "/usr/local/lib/mjpg-streamer/output_http.so -p 8080 -w /usr/local/share/mjpg-streamer/www" -b

    as you see the webcam does not support MJPG. Also you can get away with software encoding, it will eat so much CPU that you do not really want that solution. So best is to use another webcam.

    Next problem is that the script concludes best resolution is 0x0 with 0 frames which makes the final problem. YOu need to correct mjpgStart in /usr/local/Repetier-Setup/bin

    before the last line add
    BEST_WIDTH=320
    BEST_HEIGHT=240
    BEST_FRAMERATE=15

    that should fix the missing params from detection process and override it with values that hopefully work.

    I have tried to modify mjpgStart without solved the problem.

    I will buy a PiCAM, it is a good idea ? What is the best webcam for compatibility with Repetier Server and cost saving ?

    Thanks.

    Picam 2 works for me but also different Logitech models work. Picam has a short cable only so you would also need a cable extension in most cases. You can also google for "compatible webcam raspberry" and find lists of compatible webcams (hopefully also mentioning mjpg function which is a important part to have no extra load).

    Hello, 
    I have buy a Picam 2 and its works very well and out of the box ! ;)

    For a long cable i use this version: https://www.tindie.com/products/freto/pi-camera-hdmi-cable-extension/

    Thanks a lot for your support.
