I tried to install the av package on centos7 server with R 3.5.3 but am
receiving an error. I installed ffmpeg and ffmpeg-devel on centos 7 as below
and then followed the instructions of specifying LIB_DIR and INCLUDE_DIR for
installing av.
any help would be appreciated. Thanks
```
> install.packages('av', configure.vars =
> c("LIB_DIR=/usr/lib64","INCLUDE_DIR=/usr/include/ffmpeg"))
