FFMpeg unable to generate VP9 Full Range videos ?

Description

Summary of the bug:
I don't understand how to produce VP9 in full range mode (0-255). Regarding the WebM documentation it is possible to use the "full swing (0-255)" mode but unfortunately all my attemps in FFMPeg have failed. The "color_range=2" flag produce the exact same file than "color_range=1".

Of course the gbrp pix_fmt is working correctly and produce a true RGB24 file but not interesting in my case as my player can't decode true RGB.

The yuvj420p pixel format is not supported by VP9 :(

Is there a special trick I am missing ?

Thank you for your help!

yuvj420p pixel format is not supported by VP9 :(

It is deprecated. So not supported at all in any format.

But see https://patchwork.ffmpeg.org/project/ffmpeg/list/?series=9123&state=*

ok! Very intersting ticket. So if I understand correctly, we don't have workaround to get full range in VP9 files correct for now?
