java.lang.NullPointerException when opening an age restricted video

[Duvio]

• I am using the latest version - 0.21.7
• I checked, but didn't find any duplicates (open OR closed) of this issue in the repo. HOWEVER, i think that All types of age-gated videos don't get loaded #6403 might be a duplicate, but i am unsure!!
• I have read the contribution guidelines given at https://github.com/TeamNewPipe/NewPipe/blob/HEAD/.github/CONTRIBUTING.md.
• This issue contains only one bug. I will open one issue for every bug report I want to file.

Steps to reproduce the bug

1. Search for "https://youtube.com/watch?v=6-Q2NTYM3SM" in the NewPipe app search bar
2. Open the video
3. See the error

Actual behavior

It's shown that an error happened and the video doesnt play

Expected behavior

There should be no error and the video should play normally

It was one of those videos that YouTube wants you to verify your age for

Reproducible on LG G6 running Android 8.0.0.

Edit to add: This was on a video that was scheduled for a premiere.

[FTC55]

Reproducible on Samsung S20+ running android 11

[coggy9]

Reproducible with a OnePlus 7T on Android 11, AOSP based custom ROM.

that video requires authentication, with either OAuth Authorization header or Cookie headers

It's not just that video, it seems like all age restricted videos face the same issue.

[iiSnewoNL]

Will the bug be fixed in the next update or?

[AudricV]

Can you try the APK in AudricV#1? You should be able to watch age-restricted videos with this APK, except the ones for which playback on other websites has been disabled by the video owner (there is no solution found for now which doesn't require a login to a YouTube account for these videos).

[vehosah]

I can't even extract it

[AudricV]

@vehosah Did you enable Show age restricted content in Settings, Content and did you read carefully my comment? We are not able to extract the streaming URLs for all age-restricted videos right now.

[vehosah]

I can't even extract the zip

[AudricV]

@vehosah Sorry, I didn't understand you. Here is the direct link to the APK: https://github.com/TiA4f8R/NewPipe/suites/3378370309/artifacts/79610287. You need to decompress the APK to be able to install it. If you can't, please try an other browser to download the APK (you need to be logged on GitHub to download Artifacts).

[AudricV]

For users who have bugs with the APK you have downloaded, here is a reupload of it: app.zip

The apk is working well indeed. I hope it will work for a long time though. Thanks! 😀

[infinitewaveparticle]

@TiA4f8R Does this apk also include the fixes for buffering?

Well I don't have any issues concerning buffering, but what helps for me is reloading the video and playing it again. 👌

[AudricV]

The crash has been fixed for all age-restricted videos (and unavailable videos) with TeamNewPipe/NewPipeExtractor#604. You will be able to watch age-restricted videos (except the ones for which playback on other websites has been disabled by the video owner) in the next release.
