But unfortunately I am getting the famous "streaming stopped, reason not-negotiated (-4)" error message as seen below.
I have tried changing some of the parameter when launching the gst-launch-1.0 but it is always ending the same way.
Can someone give me some advice on how to get the system to work? Even if it implies changing the montor type or camera or software upgrade or downgrade. After all, all I am instrested in is to see the H264 compressor work with a live stream.
