Description

The currrent yt-dlp only can specify --ffmpeg-location and the other downloader need to same path of yt-dlp or need in the PATH. This issue propose a new option --dependency-path that can extend --ffmpeg-location for another downloader or another dependency.
Example :
--dependency-path ffmpeg:<FFMPEG_PATH>, aria2c:<aria_path>, AtomicParsley:<atomicparsley_path>

We can even make this even further if we include plugin.Example:
--dependency-path plugin:<plugin1_path>,<plugin2_path>
