[FFmpeg-user] Protocol whitelist and SDP files

[Ben Barker]

Ah...OK it seems the solution was the addition of:

-protocol_whitelist file,udp,rtp


(in my case the SDP points at RTP video transported using UDP)

This only seems to be an issue for any input that needs to access a
remote video source...? I don't have to explicitly add a whitelist if,
for example, opening a local video file. I assume that is the
intention behind the change...?
