rtsp socket timeout not working

Reported by: sporn Owned by:

Version: git-master Keywords: socket timeout windows

Analyzed by developer: no

Description

Summary of the bug:
Stream does not connect. In code I get an error -138 (socket timeout) after about 20 seconds even though I have set the socket timeout to 60 seconds. It looks like ffmpeg isn't setting the windows socket timeout correctly.

VLC connects and displays this feed correctly (it takes about 22 seconds to start playing)

How to reproduce:

% ffplay rtsp://kcanda.onthewifi.com:554/onvif1 -stimeout 60000000
ffmpeg version windows 4.0
built on ... 2018-04-24
