Comment:

 I'm adding the full command line output in an attempt to make this a valid
 ticket, although for this specific case it shouldn't really be needed.
 Anyone who has ever seen an SDP message ever, knows that starting with
 "SDP:" is not valid.

 Test command:

 {{{
 ffmpeg \
     -re \
     -i video.mp4 \
     -an \
     -c:v copy \
     -f rtp \
     -sdp_file video.sdp \
     "rtp://127.0.0.1:5004"
 }}}

 Generated SDP file:

 {{{
 SDP:
 v=0
 o=- 0 0 IN IP4 127.0.0.1
 s=No Name
 c=IN IP4 127.0.0.1
 t=0 0
 a=tool:libavformat 58.29.100
 m=video 5004 RTP/AVP 96
 a=rtpmap:96 H264/90000
 a=fmtp:96 packetization-mode=1; sprop-parameter-
 sets=Z0LAH9kAUAW7ARAAAD6QAAu4CPGDJIA=,aMuMsg==; profile-level-id=42C01F
 }}}

 Offending line:

 {{{
 SDP:
 }}}

 Expected SDP file:

 {{{
 v=0
 o=- 0 0 IN IP4 127.0.0.1
 s=No Name
 c=IN IP4 127.0.0.1
 t=0 0
 a=tool:libavformat 58.29.100
 m=video 5004 RTP/AVP 96
 a=rtpmap:96 H264/90000
 a=fmtp:96 packetization-mode=1; sprop-parameter-
 sets=Z0LAH9kAUAW7ARAAAD6QAAu4CPGDJIA=,aMuMsg==; profile-level-id=42C01F
 }}}

 Tested version: latest available as of right now in John Van Sickle's
 website: https://www.johnvansickle.com/ffmpeg/

 Full, uncut console output generated with '-report' and provided in the
 attached file.
