Thanks Devin! I will recompile with libklvanc but I am a bit new at compiling, I have been going off of this guide- https://gist.github.com/afriza/879fed4ede539a5a6501e0f046f71463
Would I just add- sudo apt-get update -qq && sudo apt-get -y install \ autoconf \ automake \ build-essential \ cmake \ git-core \ libass-dev \ libfreetype6-dev \ libtool \ libvorbis-dev \ libklvanc \ pkg-config \ texinfo \ wget \ zlib1g-dev sudo apt-get -y install \ nasm yasm libx264-dev libx265-dev libnuma-dev libvpx-dev \ libfdk-aac-dev libmp3lame-dev libopus-dev Then- cd ~/ffmpeg_sources wget https://ffmpeg.org/releases/ffmpeg-4.1.3.tar.bz2 tar -xvf ffmpeg-*.tar.bz2 cd ffmpeg-*/ PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \ --prefix="$HOME/ffmpeg_build" \ --pkg-config-flags="--static" \ --extra-cflags="-I$HOME/ffmpeg_build/include -I$HOME/ffmpeg_sources/BMD_SDK/include" \ --extra-ldflags="-L$HOME/ffmpeg_build/lib" \ --extra-libs="-lpthread -lm" \ --bindir="$HOME/bin" \ --enable-gpl \ --enable-libass \ --enable-libfdk-aac \ --enable-libfreetype \ --enable-libmp3lame \ --enable-libopus \ --enable-libvorbis \ --enable-libvpx \ --enable-libx264 \ --enable-libx265 \ --enable-nonfree \ --enable-libklvanc \ --enable-decklink I have been running these lines, both play fine but I think I am a little confused on defining the file and defining the output.. Maybe I should be defining the output to be the same as the file type? ffmpeg -i /home/matt/VideoTests/720ts_6DK01H_tru720og.ts -ar:a 48000 -pix_fmt yuv422p -f decklink -s 1280x720 -r 60000/1001 -a53cc 1 -map 0 -vcodec v210 "DeckLink SDI 4K" ffmpeg -i /home/matt/VideoTests/720ts_6DK01H_tru720og.ts -ar:a 48000 -s 1280x720 -r 60000/1001 -pix_fmt yuv422p -f decklink -a53cc 1 -map 0 -vcodec v210 "DeckLink SDI 4K" Thanks for your help and happy new year! -Matt ________________________________ From: ffmpeg-user <ffmpeg-user-boun...@ffmpeg.org> on behalf of Devin Heitmueller <devin.heitmuel...@ltnglobal.com> Sent: Monday, January 3, 2022 9:48 PM To: FFmpeg user questions <ffmpeg-user@ffmpeg.org> Subject: Re: [FFmpeg-user] 608/ 708 Closed Captions output with ffmpeg and Decklink On Mon, Jan 3, 2022 at 3:00 PM Matt C <asp...@hotmail.com> wrote: > Have tried these lines, they all play fine out the SDI but no captions show: I haven't tried your actual files, but there are two likely issues here: 1. Your ffmpeg build needs to be compiled to make use of the libklvanc library. That is necessary to produce the SDI VANC data that makes up the CEA-708 captions. https://github.com/stoth68000/libklvanc 2. You must use the v210 codec. If you use "-pix_fmt uyvy422" that puts the decklink output into 8-bit mode, which won't work with 10-bit VANC (as required for CEA-708).
