I'm on CentOS 7, using ffmpeg.
When I tried to do the "go get" for the first time, I got
In file included from src/github.com/socketbind/drone-control/decoder/h264dec.go:9:0: ./h264_decode.h:4:32: fatal error: libavcodec/avcodec.h: No such file or directory #include <libavcodec/avcodec.h> ^ compilation terminated.

Then, I typed
sudo ln -sf /usr/include/ffmpeg/* /usr/include/
and "go get" again.

However:
h264_decode.c: In function ‘h264dec_new’: h264_decode.c:11:12: warning: assignment makes pointer from integer without a cast [enabled by default] h->pkt = av_packet_alloc(); ^ h264_decode.c:17:47: error: ‘AV_INPUT_BUFFER_PADDING_SIZE’ undeclared (first use in this function) h->inbuf = (uint8_t*) malloc(INBUF_SIZE + AV_INPUT_BUFFER_PADDING_SIZE); ^ h264_decode.c:17:47: note: each undeclared identifier is reported only once for each function it appears in
