    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • FFMpeg access AVFoundation usb subdevice camera on OSX Mojave

    20 août 2020, par Retiarius

    I Have a dual USB camera for VR : two cameras, one usb connection. On linux, this appears in /dev/video0 and /dev/video1 and I can capture using ffmpeg -i /dev/video0

    



    On Mojave, I can see both devices in the USB hub :

    



    USB 2.0 Hub:

Product ID: 0x0101

    Extra Operating Current (mA):   0


    



    But when I list devices, I can see only one [0] :

    



    ffmpeg -f avfoundation -list_devices true -i ""
    [AVFoundation input device @ 0x7fae5b501a80] AVFoundation video devices:
    [AVFoundation input device @ 0x7fae5b501a80] [0] Stereo Vision 2
    [AVFoundation input device @ 0x7fae5b501a80] [1] FaceTime HD Camera
    [AVFoundation input device @ 0x7fae5b501a80] [2] Capture screen 0


    



    capturing from this device captures from one of the cameras.

    



    How can I get ffmpeg to detect the second usb device as well ?

    


  • How to access builtin webcam from a docker container using ffmpeg ?

    1er novembre 2020, par philippos

    I have wrote my code that captures videos by my builtin webcam of my MAC using ffmpeg.

    On local machine, the code works fine. However, I built a docker container of my code, and tried to run it, but I got the following error :

    


    error: Command failed: ffmpeg -f avfoundation -framerate 30 -i "0" -target pal-vcd -vf scale=640x480 -flags +global_header -f segment -segment_time 10 -segment_list ../out.csv -segment_format_options movflags=+faststart -reset_timestamps 1 -strftime 1 %Y%m%d-%H%M%S.mp4

    1. as far as what I understood from this log, is that the docker
container doesn't have access to local devices.
      According to
this discussion Docker - a way to give access to a host USB or
serial device ? , I need to use the --device flag to pass my
device's location.
      However, according to this answer,
that is not possible ?

      2. 


    2. In addition to what I've mentioned
above, I couldn't get my webcam's path at the first place. what is
a correct path for macbook webcam

      3. 


    


    My question is : How to access my MAC's builtin camera to record from a docker container ?
