[FFmpeg-user] Default RGB to YUV conversion

[Florian Friedrich]

Dear Carl Eugen,

Before looking into the source code (I¹m not a professional programmer and
it¹s hard to follow the route of the pixels), may I ask this question
please:
Is there a way to influence the initial RGB->YUV conversion, picking
either 601 or 701 or something else?
I got the impression that there is no parameter and the initial conversion
always follows 601 equasions.

Thank you in advance,

Florian
