In github here is the file I THINK (if it was me attempting this) you would have to modify- https://github.com/OpenHD/Open.HD/bl...t_functions.sh

I cannot tell you what to do from here. This is not enabling some setting or turning something on. You would have to change some code to make this work the way you want.

Some things to consider-
- You are probably running openhd at 1280x720. So I dont think taking a higher resolution screenshot will give you a better picture. It will just be bigger and take more space. What resolution is the screenshot the system captures?
- You could increase the resolution of the transmitted signal but you can only go so far before your airpi, bandwidth, latency, and general performance will suffer.

The ultimate fix I think is described here-

It is possible and I have done it but it is experimental and not well tested. It is a feature I would really like to see. I think picamera library and using a splitter might be a good solution to this problem.

As far as recording to sdcard on the groundpi that became broken when the distributed image became read only again. If you try sdcard recording you see on your sdcard a new partition is created and video file. However no videos get recorded. This should be fixed soon as the next image should be back to read/write

>That is the boot partition. You need to mount the root partition.

The files you do not see on the sd-card are on a second partition with ext4 file-system
Not possible to mount with Windows

If you want to see this partition and files you can use a free programm named Linux Reader.
You can download here:
https://www.diskinternals.com/linux-reader/

Supported is read ext4, ext3, ext2, ReiserFS, HFS(+) and exFAT.

Thnx Guys.

I will start with this even if I do not have a slightest clue about Linux, programming, code et.c - but you know every journey has a starting point

Just tested one more camera Wide View 2.8mm Lens H.265 IPC Board 1080P Hi3516E CMOS sensor DIY CCTV IP camera module, worked perfect on OpenHD with Pi0 using external USB to LAN adapter.
IP board 1080p camera based on Hi3516E also working perfect with OpenHD (3 min 45 sec)

Hi,
I designed case for rpi zero and AR9271HP WiFi card, maybe would be useful for someone

Multiple senders


Just wonder if two openhd drones transmitting at the same time nearby would interfere each other causing receivers to receive all frames from both wifi transmitters?

It seems a great solution!!
You have used an adapter lan <> usb becaouse you use a pi zero, do you have tried to connect directly the camera to a raspberry with a lan port through the lan cable?
