[FFmpeg-devel] ffmpeg for CentOS 7 tutorial is broken

[grady player]

do you have a opus build?
on my build system opus.pc is in the root of opus-1.1
if that is the case for your system you should be able to set:

export PKG_CONFIG_PATH=/path/to/opus then rebuild

if you have multiple paths for pc files you can separate them with a colon `export PKG_CONFIG_PATH=/path/to/opus:/path/to/other/thing`

you can also build ffmpeg without opus if you dont need it.
