The VideoLAN Forums

I am using VLC to play Youtube videos. Many Youtube videos play fine. Occasionally I encounter some videos which vlc cannot play smoothly without stuttering. I am running v3.0.17.4 (64 bit) however I have tried both the 32-bit version and the previous version of vlc (3.0.16) with the same results. I have tried many setting changes which are supposed to address the problem of playing videos smoothly on youtube without any difference. To isolate the problem here is one video which causes issues on vlc playback https://www.youtube.com/watch?v=-AvjkQtP_U8 . I have also tried these alternate URLs of the same video https://www.youtube.com/embed/-AvjkQtP_U8 and https://youtu.be/-AvjkQtP_U8. I have made the following settings changes: I have disabled hardware-accelerated decoding for the Input & Codec Settings, I have increased the file cacheing and network cacheing values to 1500 each. I have unchecked Cookies Forwarding for the HTTPS input for Action Modules. Other that that, the settings are the default. I am using a updated copy of youtube.lua. If I disable the video output in VLC settings the audio runs smoothly.

Can someone please try this video and see if they have similar results? Any help resolving this issue would be appreciated.

Here are the debugging messages when I run the video: https://pastebin.com/GWTnRqrB

Youtube is throttling the bandwidth for third party programs, so it works more or less for resolutions up to 480p but not for HD:

Thanks for responding. Did you try this video and did it show the same symptoms for you as it did for me? For me on playback, the stutters ALWAYS happens consistently in the SAME spots in the video. In addition I have tried this video on other 3-party programs (NewPipe for Android) and it does not have the same playback issues. It is possible that the other app is not playing the video in the same resolution as vlc.

the stutters ALWAYS happens consistently in the SAME spots in the video.

And where exactly ?

Please open Tools -> Messages (set Verbosity to 2) before you start the playback, and then paste the full resulting log here or on Pastebin.com or Justpaste.it if it's too long.

I can't tell you anymore because ALL youtube videos have stopped working for me. I'm not sure if it is because of setting changes I've made or something Youtube has done which requires an update to the youtube.lua script. From memory, the first stutter happens at 2s, there are additional stutters which happened at consistent times.

Yes I anticipated this would be needed and so I added the log in my first post. Here it is again:

Yes, same for me. That's what I got:

I'm afraid they have the protection scheme once again so there is not much we can do but to wait for an updated LUA script or to use the YT-DLP workaround:

OK. I guess we'll hang tight and hope for an updated lua script. Thanks for checking.

Thank you so much! it worked instantly! I've had the same problem and had been looking so far for a solution.

doesn't work for me

I can confirm this works now (for the most part - one video didn't work?). Make sure you move old unused/backup luac files out of the playlist directory, don't just leave them in there.

that's after I put this Lua file that you talked about, I don't know if it is something I did or if this script doesn't work, but as it is in the image, it didn't work and on my VLC, youtube does not work

Thank you!!! I wonder why I had to manually replace it, you'd think it should be automatically replaced upon updating.

I tried this one and it didn't work, still has the "Couldn't descramble YouTube throttling URL parameter" problem

youtube.lua redirect https://www.youtube.com/watch?v=-AvjkQtP_U8 to Which streams 50kb/s

Other program redirect it to Which streams 5Mb/s

It seems youtube.lua redirects slow links, Something seems needs to be modified on youtube.lua to redirect fast link
