nginx audio track for hls module installation - linux

Question

I started to configure a setup with nginx audio track module and I encountered a few problems.
First of all, I started from the official documentation.
I followed the requirements and installed ffmpeg.
As far as I can see, the available libs are:
/usr/lib/x86_64-linux-gnu/libavformat.so.58
/usr/lib/x86_64-linux-gnu/libavutil.so.56
/usr/lib/x86_64-linux-gnu/libavcodec.so.58
When I run make install the following output is generated:
/root/dev/nginx-audio-track-for-hls-module/ngx_http_aac_module.c: In function ‘ngx_http_aac_extract_audio’:
/root/dev/nginx-audio-track-for-hls-module/ngx_http_aac_module.c:156:5: error: ‘av_register_all’ is deprecated [-Werror=deprecated-declarations]
156 | av_register_all();

This is only a short sample, there are many with the same error message.
