Below are steps how to test on your local host:
wget --no-check-certificate https://samples.ffmpeg.org/MPEG2/interlaced/burosch1.mpg

1. interlace format:
ffmpeg  -re -i ./burosch1.mpg  -c:v bitpacked  -pix_fmt yuv422p10  -f rtp  rtp://239.255.0.1:6000
copy and create sdp file test.sdp
ffplay -buffer_size 671088640 -protocol_whitelist "file,rtp,udp"  test.sdp

2. progressive format:
ffmpeg  -re -i ./burosch1.mpg  -vf yadif -c:v bitpacked  -pix_fmt yuv422p10  -f rtp  rtp://239.255.0.1:6000
