THERE IS NO AUDIO IN THIE VIDEO FILE.
But when you use VLC and use command
udp://@:5000
there is no output of the video, and if you use "Tools"->"Statistics" and you will see there is NO VIDEO PACKET coming in instead of AUDIO
LINUX version is ok but it only happened in WINDOWS version
followups : windows version mpv is ok but not VLC.
