Nvidia Tegra K1 video cards and Hardware Accelerated Video Decoding produces pixelated video, even when run on local machine (without networking errors)

Reported by ahti.a...@playmoregames.com, Sep 22 2017

Issue description

Chrome Version       : 60.0.3112.114
OS Version: 9592.96.0

     IE 7/8/9:

What steps will reproduce the problem?
1. Using a specific Chromebook. Acer Chromebook 13 CBS-311 and some HP Chromebooks will do the trick; one feature common is Nvidia Tegra K1 video card.
2. Then finding a video, which is encoded with some specific encoding; not sure which one. This one has the encoding, which will result in reported issue: https://www.youtube.com/watch?v=gEJdd1a1cKA&t=9s
3. If you have Hardware Accelerated Video Decoding enabled, the video will be pixelated, no matter how good your network is; I work for Dized and the video gets pixelated when I run it on my local disk.

What is the expected result?

The video should be decoded as it is decoded when the Hardware Accelerated Video Decoding is disabled: without the messy pixelation.

What happens instead of that?

The pixelation happens.


Please provide any additional information below. Attach a screenshot if
possible.

I have a possible fix for the issue, but I am unable to implement it, because it would require building Chrome by using this hack: http://elinux.org/Tegra/Downstream_SW/Linux4Tegra/WebBrowsers/Hardware_Accelerated_Video_Decoding

I believe this bug is reproducible in a traditional Linux environment also. I think that by looking at this hack, your engineers could patch the Chrome OS to use similar fix, when running on a Chromebook, which has Nvidia Tegra K1 video card.
