Is your client on the same network of the camera? Is there any firewall
in the middle? Or do you have a windows firewall enabled, which blocks
the UDP traffic?
What's probably happening is that ffmpeg asks for RTP over UDP, but
something is blocking the UDP traffic... VLC solves this problem by
switching to RTP over RTSP if no packet is received after a short timeout.
Can you try to change the "protocol_mask = (1 << RTSP_PROTOCOL_RTP_LAST) - 1;"
line in libavformat/rtsp.c (around line 1061) in
"protocol_mask = (1<< RTSP_PROTOCOL_RTP_TCP);" and see if this helps?
