    v4l2: Fix 4K colorimetry · 4f7fefe7
    Nicolas Dufresne authored
    Since 1.6, the transfer function for BT2020 has been changed from BT709
    to BT2020_12. It's the same function, but with more precision. As a side
    effect, the V4L2 colorpsace didn't match GStreamer colorspace. When
    GStreamer ended up making a guess, it would not match anything supported
    by V4L2 anymore. This this by using BT2020_12 for BT2020 colorspace and
    BT2020 transfer function in replacement of BT709 whenever a 4K
    resolution is detected.
