Maybe I got it, but not sure...?

Just trying to make sure I get this right in the compile as I have not added things before.

If I add    libklvanc \    to

sudo apt-get update -qq && sudo apt-get -y install \

like this:

sudo apt-get update -qq && sudo apt-get -y install \
  autoconf \
  automake \
  build-essential \
  cmake \
  git-core \
  libass-dev \
  libfreetype6-dev \
  libgnutls28-dev \
  libmp3lame-dev \
  libsdl2-dev \
  libtool \
  libva-dev \
  libvdpau-dev \
  libvorbis-dev \
  libxcb1-dev \
  libxcb-shm0-dev \
  libxcb-xfixes0-dev \
  libvorbis-dev \
  libklvanc \
  meson \
  ninja-build \
  pkg-config \
  texinfo \
  wget \
  yasm \
  zlib1g-dev
  sudo apt-get -y install \
  nasm yasm libx264-dev libx265-dev libnuma-dev libvpx-dev \
  libfdk-aac-dev libmp3lame-dev libopus-dev




I get:
Note, selecting 'git' instead of 'git-core'
E: Unable to locate package libklvanc

Same if I try just:
sudo apt-get update -y
sudo apt-get install -y libklvanc

And
sudo apt-get update -y
sudo apt-get install -y libklvanc-dev

Sorry, new to this, what am I missing?



I will have "--enable-libklvanc" to the ./configure line once I get to that point..

Thanks!  - Matt

So the vast majority of those args are unnecessary given the file.
Assuming you've properly built with libklvanc support it should play
just fine including captions using:

ffmpeg -i /home/matt/VideoTests/1080i_TS_SampleFileCC.mpg-pix_fmt -f
decklink -vcodec v210 "DeckLink SDI 4K"

Did you add "--enable-libklvanc" to the ./configure line?  That is
needed for the libklvanc library to be included in ffmpeg.
