title_body: How to Simultaneously View and Record GoPro Content While Flying I want to be able to remotely take pictures and start and stop video using a GoPro Hero 9 Black while it's attached to a quadcopter. The pictures will need to be saved to the GoPro's internal memory card.
  I'll also need to be able to simultaneously view a live video feed from the GoPro so that I'm able to properly align the camera for taking pictures.
  I have never used a GoPro before but I've read that it has a wireless live video stream feature built in where you can see a live video feed from the camera on your phone using the GoPro app. If this is true does this work well while the drone is moving around. The drone will be used for surveying land. It will not be used for FPV racing if that has any relevance.
  Ideally I would like to be able to connect a Nvidia Jetson Nano or alternatively a Raspberry Pi to the GoPro and use something like OpenCV in combination with the &quot;unofficial&quot; GoPro API project on GitHub to automatically take the pictures and while I view a live video feed from the drone. That's the main goal but if this isn't possible then can I do it manually using the GoPro app on my phone? Any guidance or suggestions would be greatly appreciated. Thank you.
  UPDATE
  Perhaps this will help clarify my objective. I'm basically wanting to make a DJI style controller with the phone screen that let's you see where you're going and to have a feature that lets you take pictures manually or autonomously using AI/OpenCV.
upvoted_answer: I don't have any experience with that API, but I read through the documentation so I will try to give the best answer I can based on this and the comments below the original question.
  I would recommend using an either an Arduino or Raspberry PI pico. If you do that you can use the arduino library based on the goprowifihack API (Arduino libraries works for the Pi pico).
  The only downside I see to this is that it does not support live streaming, so you would need a separate solution for that. The best solution here would probably be to mount an FPV camera in the same direction as the GoPro and then use a regular video transmitter. You could also use the HDMI output of the GoPro I think, but I don't know of a way to transmit that video without adding considerable weight.
  To control the Arduino (or any other microcontroller of your choosing), the same rx reciever that you already have can be used. I don't want to comment on exactly how to do this as I don't feel qualified, but there are libraries for both SBUS (You can split the cable to go to both your flight controller and the Arduino, you just have to know which channels should do what) and PPM for example.
  If you then for example set up your transmitter so that a switch corresponds to channel 8 and then program the Arduino to activate video recording, the switch on the transmitter will work as a start button for video. You could also set it up so that video is on when the switch is in one position, and that it turns off in the other direction. Repeat this for all the functions you need and it will be as close to a DJI drone as possible. As a bonus it will be a lot more flexible than a DJI drone.
  This shouldn't add too much weight if you use a lightweight microcontroller (just remember that you need WiFi as well, either built in or a separate board).
