Thanks for the update, and your quick answer.
I guess the free version do not handle vimeo HLS links then. I get the error “video not found”.
I followed your instructions to embed my HLS links.
The link from Vimeo looks like :
https://player.vimeo.com/external/153*****7.m3u8?p=high,standard&s=9130ded6d9341a9e03d32241a20240cc48f547db
I tried it with no luck
I also tried a sort of “short version” of it :
https://player.vimeo.com/external/153*****7.m3u8
still no luck

– I tried with both visible and invisible on Vimeo Pro
– I tried with domain restriction of vimeo pro (only my domain)

but maybe I must buy the premium player ? if the answer is yes, I buy it right now. I really need to serve my video with HLS to that people stop downloading my links.
