_static_decrypt_signature function in youtube.py

[RealDeviil]

Are you guys no longer updating the decryption code for each signature length in the '_static_decrypt_signature' function in youtube.py?

I noticed that the code for signature length 83 (in that function) is no longer working?

If you are no longer updating this code, or you're phasing out this method in favor of automatic signature decryption, could you kindly explain how I can continue to manually generate the signature decryption code found in _static_decrypt_signature?

Thanks!

We are phasing out static signatures, but we simply hadn't noticed the 83 change, fixed. Internally, we use the --youtube-print-sig-code flag to generate the static signature code. However, we make no guarantees that that flag will continue to exist, or have any kind of stable output format. There are only a couple of URLs (most prominently, the age restricted ones, see #1495 ) that fall back to the static signatures.

Thanks a lot! Where can I find the code that handles that flag: --youtube-print-sig-code ?

I've written some PHP software that does a lot of what youtube-dl does, and I'd really like to learn how you guys were doing manual decryption code updates (prior to introducing the automated signature decryption). I'm still doing manual decryption code updates for my software -- for now.

Perhaps at some point, I might try to translate your "automatic-signatures" commit code from Python to PHP. But I need to learn some more Python before I attempt that. ;-)

The --youtube-print-sig-code implementation is pretty boring.

If you port the automatic signature exctraction to php, please drop me an email with a link to the repository. We'll find a way to link to it then - this is a forum about youtube-dl, and we'd like to keep off-topic discussions off.
