How can I get audio key?

[staniel359]

Hello.

From my console I try to call session.audio_key().get_audio_key(track.gid, file.file_id) but after some time it returns _queue.Empty.

What's the problem?

Please provide debug logs according to README.md.

As a general troubleshooting, could you please check if the music is restricted by country or account type, or if it is available in a different codec?

[staniel359]

@kokarare1212 It's not restricted as session.content_feeder().load() worked. If I run it, I see that file_id is c04e355b9f4606b21f94b2a4de5db26aeca0163f (for .ogg 160). Also track's spotify id 29d0nY7TzCoi22XBqDQkiP converts to 46982c56ce8f4470a377026e2fe1ac2f global id.

[kokarare1212]

Ah, I missed something important. The argument passed must be bytes, not hex.

[staniel359]

@kokarare1212 But I pass it as b'id_value'.

[kokarare1212]

No, it is not.

session.audio_key().get_audio_key(b'F\x98,V\xce\x8fDp\xa3w\x02n/\xe1\xac/', b'\xc0N5[\x9fF\x06\xb2\x1f\x94\xb2\xa4\xde]\xb2j\xec\xa0\x16?')

[staniel359]

@kokarare1212 I see. How can I convert them to these values?

[kokarare1212]

You can use this: https://docs.python.org/3/library/stdtypes.html#bytes.fromhex

[kokarare1212]

No, it's Shannon Cipher( https://www.cantorsparadise.com/shannon-ciphers-and-perfect-security-d70c10379ac2 )

@kokarare1212 Thanks!
