Did you choose RTSP in the settings of the OpenBot app?

Yes, I know that there are WebRTC and RTSP in Stream mode. And I set it to RTSP.

@izivkov any ideas?

izivkov commented 2 years ago

I think unfortunately, some phones are just not compatible with the "cv2" library we are using in the Python program for video. There is no easy alternative, since this is the default official Python library. At one time we tried to replace with VLC library, but AFAIR it just invoked a separate VLC player. So here are some suggestions:

  1. Try a different phone, something more close to standard Google phone, like Motorola or Pixel. Mind you most phones should work.
  2. Use VLC program for video streaming. Run the Python program without the --video flag.
