Cannot parse keys from audio adaptationset

[lwerdna]

Shows up as:

Traceback (most recent call last):
  File "/path/to/Downloads/web-dl/./web-dl.py", line 49, in <module>
    main()
  File "/path/to/Downloads/web-dl/./web-dl.py", line 35, in main
    video_keys, audio_keys = decryptor.extract_keys(args.url())
  File "/path/to/Downloads/web-dl/modules/decryptor.py", line 129, in extract_keys
    selected_adaptationset_audio_idx = adaptationsets_audio[0][0]
IndexError: list index out of range

since adaptationsets_audio is empty. The audio adaptationset element doesn't contain "lang" in my case, so the loop in decrypt.py passes over it and doesn't pick up the keys.

Here's the offending dash manifest: stream.mpd.zip

Got the same error, how to fix it?

[] AdaptationSet #0: (?)
[] AdaptationSet #1: (audio, \x7f\x7f\x7f)

Hello, thanks for commenting on the issue! From what I remember, there are some fields in the manifest which greatly vary between instances, and I couldn't find any common specification on how the structure should be for these kinds of media.

If you're able to attach the manifest file, it'll help a lot to adapt the implementation and try to make it more robust.

I'm currenly working actively on some other projects, but eventually I'll come back to this one and try to resolve all posted issues.

Thanks again for the contribution and for your interest, it's very much appretiated! 😄
