Research direction

The issue requests conversion of Bilibili .m4s video files to MP4, but names no source files or tests. Start by reading the project’s existing video conversion entry points and checking whether they support .m4s; the issue says the sample file could not be uploaded. Done means an unencrypted .m4s file from Bilibili can be converted to MP4.
