Quote from CroqueMr

Nice we can continue our discussion here I sent you a mail but I will past my answer here also :

I use YCbCr inside the RGB 8bit tunnel to avoid unnecessary conversions and rounding and help small GPUs. I send the matching YCbCr to RGB and RGB to LMS matrices for the TV to handle the conversion in TV-Led mode, following ETSI specs

For your comparison, do you need IPT PQ c2 inside the RGB tunnel, like the earlier Yblod build? Just tell me what output and tunnel format you need, I can adapt the Master Reference circuit to match your need. Other circuits deliberately modify the signal and aren’t intended as exact references and I think do not deserved to be deeply analyzed

Yes, to ensure 100% accuracy in the analysis, I need all players to use the same color space. Otherwise, I’d have to convert ITP to YUV or vice versa, and that isn’t a lossless process—I need a lossless process without any color conversions.
I’m testing on an Intel i3-12100 (UHD730)—it seems to be sufficient for 30 fps tests.

Hi, I joined your project over a week ago.
I have a question for the developers of these two projects, CroqueMr and dangerouslaser
The first releases sent an 8-bit RGB signal in ITP color space through the tunnel, just like all players with DV do, but starting with a certain version, I see that YCbCr is being sent instead.
What’s the reason for this? I know that both options are considered acceptable, but I’m curious to know why.
I’ve already tested the ITP option and compared it with other players, and it worked great; I’m still testing the new version. But since the color representation is different, it’s not possible to perfectly align the signals for comparison with other players.
In the YCbCr tunnel output mode, are all the necessary RGB-to-LMS conversions being performed?
