    • RE: Getting voxl-streamer running

      Our dev repo is very active and occasionally we end up with some dependency mismatches in it. I fixed the problem with voxl-streamer. Can you please start with a fresh install of the system image and follow the instructions in this thread to try again? It should all be working now. Thanks!

    • RE: M500 Camera Feed Upside Down

      That's correct, QGroundControl has no way to change the video orientation. And yes, voxl-streamer does have an option to rotate the video 90, 180, or 270.

    • RE: Example to stream video via ffmpeg

      Can you please send us the output of "ls -l /dev/frame0", the output showing hello_hal3_camera, and also ffmpeg?

    • RE: Stream the video data via WIFI

      @Ruijie-Geng Yes, you certainly can. However, using WIFI usually results in local IP addresses which are not routable over the Internet. For someone to connect to your WIFI video stream from the Internet you will need to make your IP address visible to the Internet. There are different ways to accomplish this but we usually use a VPN for this purpose. We have some documentation on VPN use with Voxl here: https://docs.modalai.com/voxl-vpn/

      Also, you have to start the camera application that creates /opt/frame0 before starting the docker. Otherwise the docker will create /opt/frame0 itself as a directory and not as a pipe. If this happens, exit the docker, delete /opt/frame0, start the camera application, then start docker.

    • RE: M500 Camera Feed Upside Down

      How are you viewing the video? In some viewers, such as VLC, there is a way to rotate the image.

      Okay, so don't do the auto download and install of packages after flashing system image 3.1.0. And don't run any of the voxl-configure-* scripts. See if you can just flash system image 3.1.0 without any other packages and then run the steps.

      If you try to build from scratch on the master branch you will have a version skew and see these errors. You need to be using the dev branch if you are building from source. I would recommend, however, before doing that, to try using our prebuilt binaries from our package repo to make sure everything is working properly. First, reflash system image 3.1.0 on to the board. Then, on target, follow these steps:

      1. Setup Internet access (e.g. WiFi), then reboot
      2. Verify Internet connectivity
      3. Edit /etc/opkg/opkg.conf to uncomment the last line. This will give you access to our dev package repo at http://voxl-packages.modalai.com/dev/
      4. opkg update
      5. opkg install voxl-camera-server
      6. opkg install voxl-streamer
