I don't get how it works.

Wouldn't YouTube just compress/re-encode your video and ruin your data (assuming you want bit-by-bit accurate recovery)?

If you have some redundancy to counter this, wouldn't it be super inefficient?

(Admittedly, I've never heard of "fountain codes", which is probably crucial to understanding how it works.)
