hello, I'm using ffmpeg with following command:

ffmpeg -threads 2 -y -i rtsp:// 
-f flv xx.flv 
-f rtp -an rtp://>xx.sdp

the second output does not work.I test it by ( ffplay xx.sdp ), it print
"xx.sdp: Invalid data found when processing input"
is there any mistake with the command?

if i use ffmpeg -y -i rtsp: -f rtp -an
only one output, then ffplay this file(xx.sdp). it can work.

please help me,thanks!
