How do I get 1440p Youtube videos to actually play?

Posted

Whenever I try to play a video on Youtube that is higher than 1080p, it won't play. The player will just show me the loading animation and never start. If I wait a while, this message appears for a short time before disappearing again: "if playback doesn't begin shortly try restarting your device". Switching to 1080p, the video starts immediately and plays just fine.

These high res video's have never worked for me. In older versions of FF I had the video play garbled, with the top of the video showing an artifacty mess, and the rest of the screen showing a frozen picture or black. In newer versions of FF the above mentioned behaviour of eternal loading.

My monitor is 2560 x 1600. In windowed mode I view video's typically at 1080p, but if I then switch to full screen, Youtube automatically tries to give me the 1440p version of the video when available. And subsequently stops and shows the loading animation.

This isn't a bandwidth problem (120 Megabit connection).

I've tried FF safe mode. I've tried disabling hardware acceleration. My Nvidia drivers are recent. Disabling SLI didn't help either. My plugins are up to date, including Flash, even though Youtube had been serving me videos exclusively in HTML5 for a long time now. But just to be sure.

I would really like to watch video's in 1440p, or even 2160p in the future on a new monitor. What can I do to fix this?

Edit 1: I've added a screen shot of a video's 'stats for nerds', when trying to play at 1440p.

Edit 2: Setting "media.mediasource.webm.enabled" to true didn't help. Youtube's youtube.com/html5 page shows me seven blue checkmarks.

I don't think that there are many (or any) users around here you have a similar configuration like you have and play a video with that quality, so no one would know how to answer your question. Maybe you should ask this on a YouTube (Google) oriented forum.

There must be a few people with 1600p or 1440p monitors. Especially the latter. Youtube will try to serve 1440p to those machines if it's available and when viewing a video fullscreen. I'm not running anything exotic. SLI doesn't seem to affect the problem either, so single GPU users could have the same issues. It says at the top of this page that at least two other people have this problem, so it's not unique.

Are there any things I could try that I haven't tried yet? Tips?

I just tried playing a 4K video on my laptop (Linux Mint) 1366x768 screen it plays a little slow but it still plays. Have you tried another site such as Vimeo? To see if you have the same problem. Because if you do it might be a hardware issue.

I tried playing this video in 1440p (2K) and 4K: https://vimeo.com/93003441

Everything up to and including 1080p plays fine, and then 2K and 4K load but won't play. Just a black screen.

Downloading the 1440p file and then playing it with VLC or MPC-HC also works fine.

I'm running the latest version of Firefox and Nvidia 361.75 drivers (also the latest version). And Windows is up to date.

OK this is really weird. I haven't changed anything in the last couple of days, but I just tried some 1440p and 4K video on Youtube again, and they play!

Stats for Nerds confirms that I actually get 1440p and 2160p video. And it's now VP9.

Although one some videos it shows up as 1350p and 1351p respectively, it looks great.

I'm real happy, but I don't understand. Same FF, same drivers. Maybe Youtube tweaked something on their end (Webm/VP9-related?) I hope it'll keep working. If so, I hope Vimeo will follow suit.

Ok, so today I encountered a video that won't play. And the only difference is that it is served as AVC 1.640032 instead of VP9/WebM. Just like the screenshot in my opening post.

I haven't made any changes to my browser (no auto-update) or graphics-drivers, or anything like that. So I'm going to assume that the problem lies in AVC vs VP9.

Is there a way to force VP9?

To be clear: up to and including 1080p in AVC plays just fine. 1440p and higher doesn't play at all. But when it's VP9, it works.
