Add More Resolutions

Can you also add higher resolutions than 1080p, H264 can play 4k videos

Sorry, this is not possible. Youtube removed the 4k and 1440p h.264 streams a few months ago. 4k streams are only available with VP9.

Maybe you could update the extension with a fix to bypass that, H264 codec does support 4k videos https://en.wikipedia.org/wiki/H.264/MPEG-4_AVC

H.264 does support 4k but Youtube does not encode video in h.264 4k anymore: http://www.streamingmedia.com/Articles/News/Online-Video-News/YouTube-Stops-H.264-4K-Encoding%3B-Will-Apple-Get-on-Board-115970.aspx

It is not possible to bypass, because the 4k h.264 video does not exist. The only 4k videos on youtube are vp9 encoded. This is disappointing because many users don't have the hardware to properly decode vp9.

As a possible workaround, you can try downloading the 4k vp9 video using youtube-dl https://rg3.github.io/youtube-dl/ and playing it offline with something like MPC-HC or VLC.

Offline video players may give you better performance than Chrome's built in decoder.

Buy maybe you could add the 4k video quality on YouTube with the extension

And also you could add the color correction for the H264 codec like the VP9 codec has

This would be great if you could find a workaround so that we can play H264 videos in 4k

Hi erkserkserks, could you please make the h264ify extension switch to VP9 when streams higher than 1080p are available? Thanks for your great work btw!

He doesn't work for Youtube. He cannot make Youtube provide this.

This would be great. Force h.264 only for resolutions where it is available but still allow and display VP streams for resolutions it isn't. However it's likely that the extension simply tells youtube that it doesn't support VP decoding at all so youtube controls the list of resolutions available. Adding this feature would be a significant rewrite.
