install AV fails - libavfilter not found

[mbmott]

Hello,

I have ffmpeg-devel installed, I have a libavfilter.pc in my PKG_CONFIG_PATH and pkg-config is in my PATH, however, the install still fails complaining about libavfilter not found. Is there something obvious I'm missing here?

Thanks in advance.

Please include your operating system and install output.

RHEL6

• installing source package ‘av’ ...
  ** package ‘av’ successfully unpacked and MD5 sums checked
  Using PKG_CFLAGS=
  Using PKG_LIBS=-lavfilter
  ------------------------- ANTICONF ERROR ---------------------------
  Configuration failed because libavfilter was not found. Try installing:
• deb: libavfilter-dev (Debian, Ubuntu 18.04 and up)
• rpm: ffmpeg-devel (https://rpmfusion.org) (Fedora, CentOS, RHEL)
• csw: ffmpeg_dev (Solaris)
  For Ubuntu versions Trusty (14.04) and Xenial (16.04) use this PPA:
  sudo add-apt-repository -y ppa:jonathonf/ffmpeg-3
  sudo apt-get update
  sudo apt-get install -y libavfilter-dev
  If libavfilter is already installed, check that 'pkg-config' is in your
  PATH and PKG_CONFIG_PATH contains a libavfilter.pc file. If pkg-config
  is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
  R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'

Which version of ffmpeg do you have? You need at least 3.2.

Ahh. That's going to be the problem then. Thanks for your help.

Yeah all stock packages on RHEL are super old, it's a common problem :( I guess you need to build ffmpeg from source.
