[FFmpeg-user] gbrpf32le in filter_complex

[Mark Filipak]

I make two statements below regarding the core of the filter_complex.
I'd be grateful if you'd point out statements that are wrong.
(Of course, anything more you'd like to contribute is welcome, too.)

In the core of filter_complex, pixel format is always gbrpf32le.

It is possible to convert bt2020nc/bt2020/smpte2084 to bt709/bt709/bt709 via zscale, only.

Thanks! -- Mark.
