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.

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.
