The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
At least for MKVs, you can use MKVToolNix's header editor to add a name to the audio tracks, which most Plex clients will pick up on (e.g. in the web app: https://i.imgur.com/awhU0Z6.png). For MP4 containers, I think MP4Box can do this (one of their examples is "replace the label on an audio or subtitle track"). Other containers probably have their own methods, but I'd probably just throw them into MKVToolNix to move the streams to an MKV and edit the audio track names at the same time.
