1080p keys for this (FREE) Youtube movie?

[angrybanana]

After reading through the forum for a long while, we finally managed to figure out how to get the keys for youtube free with ads movies.

Using yt-dlp with this movie, it finds 1080p tracks but it looks like keys do not work:

--key cc9b1f83db9a5bb5bb10763032add8ae:bceafe9bf24f10f0db5483dd9dacba1c
--key bc05655fb98e5d509dac6656ee9c51f0:5ae64cc0a30645b18fd3599e01d49df7

Is someone able to get the keys for 1080p? We would really appreciate it!
Thank you.

Out of curiosity, how do you "force" youtube to play 1080p for this movie? Is it just by pure chance?

I have seen the occasional 1080p in browser, but for the majority of titles, I believe HD/FHD is only available through the app API. Which is why yt-dlp is able to find it.

Interesting. Thanks for the answer. Wonder if it's about some endpoints used by specific devices and not the browser.

I think the endpoint is the same for all, but each client (web, android, ios etc.) will have different headers and params.

Another fun fact is that you can use the same PSSH and license URL for all videos:

You don't even need one. "====" worked for me.

The request headers and request body for the Android app are shown below:

The headers that are not shown in the screenshot are just hash data and the whole request body is Protobuf encoded (with a sample not revealing too much cdm info below).
