In this case, we need some more information. Does this happen on every video? And also please convert your error report and post it below.

[duergrim]

Yes, it happens on every video. This is what it says:

[xim]

Same stack trace, same error conditions, same OS/app version, happening as of recently. Using content language GB.

[zsoltherpai]

It's the second time in the past month a youtube change - I assume - breaks this..

Have you considered making parsing not hardcoded in the application? Then it could be fixed without an app release.

[Dlnvtl]

Exact same here. Most recent version. Some videos do play but most don't. Have reported via email.

Edit: I'm also Danish but phone and app is set to GB

[theScrabi]

Maybe something special in denmark?

[infinitytec]

Same here.
US.

[duergrim]

Nope, it's not something special in Denmark. As you can see, a lot of people from different countries have this issue

[duergrim]

When do you think the bug will be fixed?

[fhchl]

Same problem here. DK but language set to GB.

[bobdenardd]

same here, french settings. got the same error with axet/vget, looks like youtube changed the html5 js code, so you'll have to change the guessing of the name of the signature function....

[TomasEkeli]

Same here, Norwegian. Seems to be all videos for a few days now, I've had to go back to the (horrible) default player.

[duergrim]

Seems like it's fixed now

[duergrim]

Thanks for the fix, I'll close the issue now

[stonerl]

@duergrim Why did you close this one? Nothing has been fixed, yet.

[duergrim]

Are you sure? It works for me now, but I'll reopen it

[stonerl]

The problem is that these errors can't be pinpointed to a specific video or location. Some videos crash the app and hours later can be played without any problems. Maybe I have a different error...

[theScrabi]

Yra thats not the decrypt error

[stonerl]

The I'm sincerely sorry.

[TomasEkeli]

This intermittency is probably because youtube are doing A/B -testing. This may be very hard to reproduce. The error has gone away for me as well.

[infinitytec]

Gone away for me also.
