avformat/rtpenc_rfc4175: support for interlace format
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
copy and create sdp file test.sdp
ffplay -buffer_size 671088640 -protocol_whitelist "file,rtp,udp" test.sdp
