FFMPEG: OPEN_INPUT: Error number -138 occurred

[Tim Tim]

Hikvision camera using ispy.

On one computer it works on the other I get FFMPEG: OPEN_INPUT: Error number -138 occurred

Ispy v7.2.1.0
rtsp:/userassword@192.168.0.139
TCP

Any idea what's going wrong?

Should the RTSP port 554 be in the URL ?

Also compare ffmpeg version on each computer, maybe a different version is causing the error.
