Could be something peculiar to Nvidia GPUs, or maybe it’s just Firefox, but I never see this colour anywhere else, only when something causes a glitch in the rendering of video content. Sometimes it’s not just the video player that goes green, but the entire viewport of the browser window. I’m mainly curious why it’s that colour, rather than just black or white or something like that.

  • HEX: 004d00
  • RGB: rgb(0, 77, 0)

    Not an answer to your question, merely an amusing anecdote, but Windows used to use a green screen (different shade though) to render videos.

    “The media player program didn’t render the video pixels to the screen,” … Instead, Windows would render a green screen (or a different color, depending on the version), then “render the video pixels to a graphics surface shared with the graphics card.” The final step was to “tell the graphics card that whenever it sees a green pixel about to be written to the screen, it should substitute a pixel from that shared graphics surface.”

    –Windows used to secretly use green screens to render videos, which is how you could trick MS Paint into becoming a video player

    I recall seeing such green on screenshots of DRM protected video on iOS (back when I still had Netflix installed)

    I assume that this is DRM protection as well, probably the same, as those streaming apps are mostly just JS these days anyway

    Trees appear green because they absorb red and blue light while reflecting green light. Maybe your TV is photosynthesising ¯\_(ツ)_/¯ I just wanted to add to the list of unhelpful answers

    I haven’t seen this exact screen, but since there’s very little help in this thread so far, I’ll speculate.

    I’ve seen plenty of single solid color screens that turned out to be “fuck you i didn’t like something, have a plain color instead of your image” from some piece of Digital Rights Management software.

    If it is DRM, the two approaches I’m aware of are:

    • Try to guess what pissed off the DRM, while being treated as an enemy at every level and step of logging and debugging.
    • Turn to the clear, communicative, well documented piracy community for help. Note that their solutions may not be strictly legal, but they tend to actually get me access to the thing i already paid for.

    This happens when I try HW decoding on VLC on an old AMD card, the video has extra letterbox bars of this color (can be cropped manually by pressing C). At first I thought it’s some default in the ITU-R BT.709 (YCbCr) colorspace used in most video codecs but those RGB values map to an uneven 55, 106, 100…

    My calculations say that YCbCr(0, 0, 0), which is presumably the default state of the video framebuffer, will become RGB(0, 73, 0) after ITU-R BT.609 colorspace conversion and gamma correction. Not exact but very close, the video might just be using a slightly different color profile from the standard. Or maybe I made a miscalculation.
