Youtube black point in Chrome

[markanini]

I'm getting a raised black point on youtube video in Chrome on my system: Win10, AMD HD7700 w/ v16.9.2 drivers
Anyone else getting this?

Here's a good video for seeing the problem https://www.youtube.com/watch?v=GT3vhcy3XaQ

EDIT: Here's a great video for detecting video output levels: https://www.youtube.com/watch?v=ikXK4YtBEVI If 0-255 it will be all black. Use it to check if your system handles HTML5 video levels correctly.

Heres a solution I found https://chrome.google.com/webstore/detail/disable-youtube-html5-pla/enmofgaijnbjpblfljopnpdogpldapoc

You need to specify that video does not have full range samples (if you're encoding). There's a checkbox for this in Avidemux in the x264 config, so I assume it's an x264 option as well.

Full range samples off (good): https://www.youtube.com/watch?v=7lwvXSMBMcE
Full range samples on (bad): https://www.youtube.com/watch?v=tgYZizkYhHo

Edit:

I just tried that video you suggested in Chrome and Firefox, and both looked fine. So maybe it's something else. A graphics card thing?

Whats your system? On my system the full range clip in HTML5 looks simmilar to the 16-235 clip in flash.

Windows 7, Nvidia Optimus graphics (Firefox and Chrome running on Intel integrated graphics).

Apparently browsers, graphics APIs and display drivers are talking past each other. Firefox used to have this issue but managed to fix it, Chrome is lagging behind on some setups.

Nah, it's solely browser fault. Media players never ever had such problems, while HTML5 video in browsers still barely works.

Anyone have experience with reporting bugs on Chrome?

EDIT: I made a bug report from Help>Report and issue...

Same issue in Opera. Not surprising as it's based on Chrome. Firefox, IE and Edge handle this fine.
If you see any grays in the test clip, linked below, in Chrome or Opera it would help to get the devs attention if you make a bug report.
