Most likely, we need to adapt one of the non-signature parameters.

Note that this is our age-gated test video. Maybe we need to tinker on 2c57c7f again?

[jaimeMF]

We extract the sts parameter from the video webpage now.

[phihag]

Great!

I am also using this video to test VEVO + age restriction and I noticed that something changed today. This video is no longer protected with a ciphered signature, its detailpage returns use_cipher_signature=False so we can extract the streams directly from url_encoded_fmt_stream_map without bothering with the js player.

You can use video pZ12_E5R3qc instead which is both age restricted and signature ciphered.

[jaimeMF]

That may be temporary, I get use_cipher_signature=True in the details page.
