How in looks in VLC (it's wrong)
and how it should look ideally

>>107580379That's not what it is at all, it's downsampling, and the issue is gamma correction, or lack thereof. And the correct result isn't arbitrary for optical reasons, as in that's how it look in a camera.
>>107579641>is there any media player that does this correctly?MPV. linear-downscaling option is enabled by default.
>>107580396What a camera does is completely different from what downsampling algorithms do. Of course you can use these alternating pixel patterns to check whether your monitor has the correct gamma settings, but linear downsampling isn't always the preferable choice for real-world content. It's easy to implement, but in many cases, bicubic or Lanczos filtering produces more aesthetically pleasing results. But they don't produce the kind of output you're testing against with that video.
>>107580412Based, thanks. What's the best frontend (Windows)?>>107580465You sound very confused. This topic is about getting overly dark averages of pixels from doing pixel math without taking gamma into account, as in, you average as many white pixels as black pixels together and you either get a 127 or 128 average (which is incorrect) or a 187 or 188 average which is correct. Which averaging method is being used is not relevant.
