ronlin99,
I think your issue is the code you're using. The quote and -o in particular. Paste the correct url within here
HTML Code:
livestreamer "hlsvariant://" best -o name.ts
remove the character in front of http if needed, and try again. I tried and copied your code string from your post yesterday and it gave me those errors for a different game. SO i re-wrote the line and the quotes and -o were the issue.
Give it a try.
