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. - -Upstream-Status: Backport -Signed-off-by: Nicolas Dechesne <nicolas.dechesne@linaro.org> - ---- - sys/v4l2/gstv4l2object.c | 7 +++++-- - 1 file changed, 5 insertions(+), 2 deletions(-) - -diff --git a/sys/v4l2/gstv4l2object.c b/sys/v4l2/gstv4l2object.c -index 61244455f..aae2c55e7 100644 ---- a/sys/v4l2/gstv4l2object.c -+++ b/sys/v4l2/gstv4l2object.c -@@ -1960,7 +1960,7 @@ gst_v4l2_object_get_colorspace (struct v4l2_format *fmt, - case V4L2_COLORSPACE_BT2020: - cinfo->range = GST_VIDEO_COLOR_RANGE_16_235; - cinfo->matrix = GST_VIDEO_COLOR_MATRIX_BT2020; -- cinfo->transfer = GST_VIDEO_TRANSFER_BT709; -+ cinfo->transfer = GST_VIDEO_TRANSFER_BT2020_12; - cinfo->primaries = GST_VIDEO_COLOR_PRIMARIES_BT2020; - break; - case V4L2_COLORSPACE_SMPTE240M: -@@ -2062,7 +2062,10 @@ gst_v4l2_object_get_colorspace (struct v4l2_format *fmt, - - switch (transfer) { - case V4L2_XFER_FUNC_709: -- cinfo->transfer = GST_VIDEO_TRANSFER_BT709; -+ if (fmt->fmt.pix.height > 2160) -+ cinfo->transfer = GST_VIDEO_TRANSFER_BT2020_12; -+ else -+ cinfo->transfer = GST_VIDEO_TRANSFER_BT709; - break; - case V4L2_XFER_FUNC_SRGB: - cinfo->transfer = GST_VIDEO_TRANSFER_SRGB; --- -2.14.1 - |
