I've made this streaming video system where the backend is a blossom server. I have a script which splits the video up into "segments" (I'm using HLS for adaptive bandwidth) to allow easy-ish uploads ...
Yes I had seen your project … still have to check out your code. I have not fully included HLS in Nostube yet. Trying to figure out what is the best codec compatibility vs. space requirements and thinking of adding AES encryption to the blossom blobs. I have a DVM that runs a similar HLS conversion… but will have a look at your script.
