Hi,

Can you please explain the difference between these two YCbCr-to-RGB
conversion functions?

The result, if it is now black, seems to match what MPC-HC's subtitle
renderer does, which was recently (a year or two ago) updated to work
more according to the HDMV graphic stream specification.

I think wm4's primary concern is that the change is not backed by any
explanation regarding why it is incorrect or if this is even the right
place to fix the issue.

Best regards,
Jan Ekström
