Any chance to get this regression fixed for 7.0 one way or another?
For remembering:
./ffprobe -f lavfi -i yuvtestsrc,setparams=color_primaries=bt470bg:color_trc=smpte170m:colorspace=bt470bg,colorspace=bt709:range=tv,scale,showinfo 2>&1|grep color_space
Current code:
color_range:unknown color_space:bt470bg ...
Release 6.1: (expected values) [or current code with my proposed patch]
color_range:tv color_space:bt709 ...

Thanks
Nicolas
