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