This breaks rtsp

example:
./ffmpeg -itsoffset 2 -re -i matrixbench_mpeg2.mpg -acodec libspeex -ar 16K -ac 1 -vn -t 3 -f rtp rtp://127.0.0.1:19745 > speex.sdp </dev/null & sleep 1 ; ./ffmpeg -protocol_whitelist file,rtp,udp -i speex.sdp -y -t 0.9 out.wav

segfaults but i think this is not specific to this one case
