function missing

[238-699]

I'm at https://docs.rs/ffmpeg-sys-next/latest/ffmpeg_sys_next/all.html?search=av_bsf_get_by_name I found this function, but actually I use ffmpeg_sys_next and it does not have this function. Does this need to be specially built? Cargo.toml ffmpeg-sys-next = { version = "7.1.0" }
