1. Connect equipment

Connect equipment as neccessary such that the encoder laptop is receiving a 1080i25 signal with embedded audio on a Decklink card.

Connection schematic as follows:

2. Set up encoder / recorder

./vlc -I dummy \
-v decklink:// vlc://quit --live-caching 3000 --sout \
'#duplicate{dst="display",dst="transcode{height=720,vcodec=h264,vb=3500,acodec=mp4a,aenc=fdkaac,ab=128,deinterlace}:std{access=udp,mux=ts,dst=192.168.0.24:6666}"'  \

-cluster_time_limit 5100 \
-content_type video/webm   \
-c:a libvorbis -b:a 128K   \
