Videos That Formerly Played No Longer Do

[MeanLauraJean]

Youtube videos that used to successfully play via the plugin no longer do. An example would be:

Any thoughts on why this worked and now no longer does?

Thanks,

The issue is signature decryption on certain copyrighted videos. This has been an issue in the past.

My logs are showing this error:
ERROR (video:258) - Cannot decrypt signature: 'NoneType' object has no attribute 'group'

@kolsys was able to come up with a clever fix last time. The details of how youtube signature decryption work are outside of my wheelhouse.

Well, signature decryption is a bit beyond me, but thankfully the folks at youtube-dl already have it fixed. I copied the regexes they use to pull out the signature decryption function and it's working again. You can pull from my fork at https://github.com/mddepew/YouTubeTV.bundle
There is an active PR to pull the fix into the main repo. #55

@mddepew looking good now, thank you :)

This is occurring again. Videos that used to play successfully no longer do. Same example:
