Sorry about that - don't know why it fails like that. Hopefully it'll work better now.

Onion site down again? Error: Onion site not found.

Seems to be down again.

NTA, but you're an idiot. SP and Erai release untouched official video, they don't encode anything, and official video is encoded with the software encoder x264. In the case of amazon they sometimes used a hardware encoder, but it's an exception rather than the rule.

Both of these are x264, which is a software encoder ran on CPU. The settings aren't necessarily that good, but streamers give it lots of bitrate so it works fine.
