FaceRecog and Selfie : Streaming error



  • Hello Everyone !

    I have installed a PiCamera V1 on the mirror and it is a lot of fun.
    I started by using MMM-Selfie, worked great. Then FaceRecognition-DNN, worked great, impressive stuff.
    However, now that both camera modules are installed, MMM Selfie can’t access the camera anymore, instead it gives the error below:

    [2020-10-07 17:18:00.325] [LOG]    [SELFIE] Error: Error: Command failed: fswebcam -q  -r 3280x2464 --jpeg 100  -d /dev/video0   --no-banner   /home/pi/MagicMirror/modules/MMM-Selfieshot/photos/201007_171800.jpg
    Error starting stream.
    VIDIOC_STREAMON: Invalid argument
    VIDIOC_DQBUF: Invalid argument
    

    My guess is that FaceRecognition is blocking the access to the camera for other module. Anyway to disable to send a notification or force the module to be temporarily disabled in order for MMM-Selfie to access the PiCamera ?

    I haven’t come across any similar topic on the forum, any pointers will be appreciated !

    Thanks and have a good one !



  • @ZeFX no… none of the modules implement resource sharing



  • Thanks for your answer… I’ll try to think about an other way then.
    Cheers
