widevine-license/v1/audio/license 429

[damingchuanqi]

When I download many songs, the request "widevine-license/v1/audio/license" returns an error code 429.

Same error:

and it doesn't distinguish between a premium and a free account.

[cynthia2006]

That's the problem. Spotify is ratelimiting licensing requests to Widevine, but it's not ratelimiting Playplay. I had no luck decrypting with unplayplay @glomatico linked.

See GladistonXD#12

[GladistonXD]

In addition to needing to log each request using the websocket method, you also need a pause between each request. In my fork, I added the --safemode option for infinite requests; it takes a while, but it was the only safe way I found.

Does your patch also work with my problem?

This should solve it.

The fork only uses the Widevine version, the .dll method had a bug in the glamatico code when generating the OGG ID, which caused this error in some songs. I haven't seen if it's been fixed. What's your usage pattern?

Thanks a lot, it worked for all songs I couldnt download right now. You should really put a pull request.

Do you got experience on how rate-limited spotify is with .dll and premium account without widevine?
I want to download 8000 tracks (each 1:50, its an audiobook):
What delays, what settings i should be aware of?

Ty in advance!

I'm not sure, but since PlayPlay hasn't changed its request verification process yet, I don't think it needs to generate delays; in theory, it uses the same method as downloading tracks offline.

[cynthia2006]

So, the Playplay support is finally in? And yes, Playplay is unrestricted when it comes download tracks offline, regardless of account being premium or not.

[GladistonXD]

In fact, PlayPlay still needs to receive two types of keys from the server in addition to the id_ogg, which are the obfuscated_key and aes_key, and the .dll performs the conversion to the key. Currently, it only supports Windows DLLs, but there haven't been any changes to the request method, so it's unlimited.

I only get a too many requests error when putting delay to zero seconds. I never got errors putting it to five. We need a function that automatically pauses downloads on error, and retries them when x-seconds are passed. Like an automatic/variable time?

In this case, the problem is in the generation of the tags, not related to the decryption key. You'd have to add a rule to retry if an error occurs anywhere in the code, because this can happen even with packet loss at any point in the process. You have to study the code, and that takes time, which I don't have. XD
