Enable libopus

[Classsic]

Hi, I tried to enable libopus on your Dockerfile adding this:
yum install -y libdrm libdrm-devel opus-devel.x86_64
and
--enable-libopus \
on configure, but get this error:
``libavcodec/libopusenc.c: In function 'libopus_encode_init':
libavcodec/libopusenc.c:337:9: error: implicit declaration of function 'opus_multistream_surround_encoder_create' [-Werror=implicit-function-declaration]
enc = opus_multistream_surround_encoder_create(
^
libavcodec/libopusenc.c:337:13: warning: assignment makes pointer from integer without a cast [enabled by default]
enc = opus_multistream_surround_encoder_create(
^
cc1: some warnings being treated as errors
make: *** [libavcodec/libopusenc.o] Error 1
Any idea whats is wrong?
thanks.

Sorry, I have no idea...

But in my experience, weird errors related to lib** on CentOS6(or 7)+ffmpeg often comes from version mismatching. I defeated them by installing newer version of lib**.
So installing newer libopus manually might solves your problem.
