Subprocesses are a pita to support and maintain in a cross-platform
project. This approach would just open up a whole new can of worms to
achieve something that FFmpeg can already do with a pipe, multiple
inputs, and -map_metadata.

Since your project already uses FFmpeg, perhaps you could use it to
encode the output and keep the metadata as well. Or provide a simple
script that would invoke FFmpeg with the correct parameters.

Regards,
Ramiro
