why would these auto generated subs be the apps purview? wouldn't it be YT platform doing all of this work and providing a CC button if the data is available. i can't imagine this being done in real time and not just some post process that is run against new content at time up upload processing.

It could as well be done the few secs after one uploads to the time it becomes available, and the same applies to all translations (to all languages).

It is one of those things I don't care (at all) to know how it is technically set up :)
