Hi,
I'm currently doing the parrot drone 2 research and at this point we are conducting a series of test. I am using Ubuntu 12.04 and the current version of ffmpeg we are using is as per below.
Once connected to the drone via the wifi. Our first aim is to get a live stream of the video so we execute this command on the terminal.
ffplay -f h264 tcp:192.168.1.1:5555
It opens the video stream then it freezes and we are left looking at a frozen movie image with the following notifications (see immediately below). I have tried adding the time duration option -t, but this didn't work. Can I ask if anyone else has had this issue before? What did you do to fix it?
