DeckLink Quad - FMPEG - Output not interlaced
Posted: Thu Aug 09, 2018 9:32 am
Hello,
I have a problem with my Decklink Quad Card. I need an 1080i Output but it only sends out an progressive Output. Did anyone else had this problem and solved it? I use the following Command:
ffmpeg -i rtmp://127.0.0.1/3/$name -s 1920x1080 -r 25000/1000 -vf scale=interl=1 -ar 48000 -ac 2 -pix_fmt uyvy422 -f decklink "DeckLink SDI (3)"
My Input is an non interlaced RTMP Stream which should be converted in an interlaced Output. If i do the same thing with the Resoulution 720x576 it worked fine.
I use the following FFMPEG and SDK (Ubuntu 18.04):
ffmpeg version 4.0 Copyright (c) 2000-2018 the FFmpeg developers
built with gcc 7 (Ubuntu 7.3.0-16ubuntu3)
configuration: --disable-yasm --enable-nonfree --enable-libx264 --enable-gpl --enable-decklink --extra-cflags=-I/$home/Blackmagic_DeckLink_SDK_10.11.1/Linux/include --extra-ldflags=-L/$home/Blackmagic_DeckLink_SDK_10.11.1/Linux/include
Thanks!
