Ytrailers stopped downloading trailers

[adminExitium 355]

It looks like the ytrailers plugin has stopped downloading trailers for some time now. I am not sure of the exact date but it's been more than a month since the last trailer that was downloaded on my server.

It just seems to throw error like the following:

This is on Emby version 4.9.1.80 with YTrailers version 1.9.3.0.

Hey @radeon. I hope this find you well. As of a couple days ago, ytailers has stopped downloading trailers. I checked the logs and I get the same error that I see a page back in the thread. Is there anything I can do to fix this or does the plugin need an update? Thanks in advance once again for your help!

Same as reported here:

Any chance you will also get the time to add the "Trailers" folder option so any trailers get downloaded into that folder?

Certainly! I've updated the plugin but not released as I'm getting a 403 forbidden when I hit the aud and vid files. Watch this space

[adminExitium 355]

Thanks.

Mine doesnt work either. Redownloaded the DLL, reinstalled, entered serial key from email, and ran the scheduled task.

I would suggest sending a PM to @radeonin the event that he doesn't see this.

any update for the trailers plugin as i haven't got an update since you posted, that you haven't released it.

Are there bigger problems?

[radeon 755]

Yeah, unfortunately a much bigger problem, there’s been a major set of changes rolled out by YouTube that have impacted pretty much every tool or system that previously allowed third-party access to trailer content. These aren’t minor tweaks. They’ve fundamentally changed how video data can be accessed, which means anything relying on that method has been affected, pretty much across the board.

At this point, it’s not about the plugin itself but the wider "ecosystem" catching up to those changes. Once things stabilise and there’s a reliable way forward, I’ll look at options for restoring functionality, but until then, there’s nothing meaningful that can be done without chasing constant breakage.

In short, it’s not abandoned, just paused until there’s a solid technical path that won’t fall apart a week later.

 

[Painkiller88 248]

Not sure if this helps but while the plugin is not working i am downloading the trailers using JDownloader and it is working.
Don't know what they are doing different but maybe you can figure out something or know some of the devs.

 

[adminExitium 355]

That's probably luck. The breaking youtube changes have not rolled out to all accounts and regions yet.

JDownloader has it's own thread for tracking similar youtube problems: https://board.jdownloader.org/showthread.php?t=48894&page=196

[Painkiller88 248]

Any updates here?

Still using JDownloader without problem, but having the plugin is way more comfortable

Thanks
