Comment (by Balling):
>color space gets incorrectly set to bt470bg instead of bt709 when not
explicitly specifying a pixel format.
Pixel format has nothing to do with colorspace/primaries/transfer. It is
completly unrelated, well, besides xyz12 and rgb stuff, where colorspace
is set to 0. E.g. pixel format P010 may be SDR 10 bit.
It is expected that BT.601 is default matrix in most situations. There is
no bug here, you have to force bt709 matrix or bt2020-ncl matrix if you
need it.
