Lightning Talk - Native Code from Elixir
summary
Shows calling FFmpeg C libraries from Elixir via NIFs, using load_nif plus C functions like enif_get_string and enif_make to convert Erlang terms, and an example that extracts a format long_name from libavformat/libavcodec (ffprobe style). Notes real problems: long C work can block the BEAM scheduler (reductions ~2000) unless run on dirty schedulers, and a C crash kills the VM. Recommends using Rust/rustler for memory safety as an alternative.
