Subject: Use a single --sout-rtp-proto string rather than multiple silently
X-Git-Tag: 0.9.0-test0~2392
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=b669af272da01fb5522d78547f5fdb42860f0330;p=vlc

Use a single --sout-rtp-proto string rather than multiple silently
conflicting booleans to select the RTP transport protocol.
