Hi everyone,

Today I would like share info on enabling smooth 4K Youtube Playback on Chrome browsers, I know most of you have high-speed internet connection but when you try to play 4K videos in youtube using the Chrome browsers the video stutters or lags a lot. The solution to this problem is to enable the GPU video decoding in your Chrome browser.

Steps:
1. First, go to advanced settings of your chrome browser and enable hardware acceleration. After that exit and reopen your chrome browser.



2. After that to verify whether are your chrome browser is using GPU video decoding or not, type chrome://gpu in the address bar of your chrome browser and you should see like shown in the pictures below.



And in the video acceleration information section you should see this:



3. And now try playing 4K youtube videos and you should get smooth playback without stutters or lags.



Thank you.

Good tips. Thanks. Now I go oc my Riva tnt2 32mb with opengl . Hopefully can go 4k 60fps smoothly

i use firefox and 4k play is smooth.
the only thing that i concern were downscaling 4k to a small windows is a bitch (the downscaling aliasing is obvious), so I keep on using 1080p settings.

Thanks!

No problem. I believe Riva tnt2 32mb with opengl is not powerful enough to decode 720p/1080p or 4K videos

So basically just turn on hardware acceleration?
The chrome://gpu serve any purpose other than confirming videos are decoded using hardware?

chrome://gpu shows all the info that the chrome browser is getting from the GPU such as what features it supports.

Quick note, this will not really give you smooth playback is your gpu doesn't support VP9 Hardware decoding(playback) (Unless you only watching AVC encoded youtube vieos )

ironically AVC give better quality thanks to higher bitrate.

Yup, Google introduced VP9 video codec to save internet bandwidth that are used by video streaming services.

But my monitor 1080p jer, even phone also got higher res

bookmarked

Park

just tried to run 8k youtube, smooth af
but i only have 2k monitor

thanks to YT shitty compression...is always better to watch videos at higher reso..if available..

1080 yt nkt same with blueray rip 1080 i download. So download > utube

Higher bitrate doesn't means better quality, VP9 supposed to be 40% more efficient than AVC. But compared to AVC, VP9 doesn't have a optimized encoder, the vp9 reference encoder(libvpx-vp9 )is really slow, and have a bad Psycho-visual optimization. There is one company keep bragging about they what so called 'The world's best VP9 encoder' to consumer but its just a commercial video encoder.

Anyway let's hope the same thing didnt happend to AOMedia Video 1 Codec(AV1)

Dont worry couple more year youtube will change to AV1 completely (Currently they started encode most popular video with AV1 Codec (Probably with the crappy reference encoder(libaom)Currently*, for resolution 720p and lower, the codec still in testting tho)

but youtube decision to use vp9 were to save bandwidth, not to provide better video quality lol.
but for 4k, yeah vp9 is a needed evil.

YouTube already stop encoding 4k video with AVC since more than couple of years ago.

All the newly encoded video with resolution higher than full HD are done with VP9 since then.

When AV1 encoding is mature enough (it is still slow now) , most likely all the video beyond 4k will be encoded with AV1 only (of course there will be AV1 versions too for those with lower resolution) .
