[FFmpeg-user] uncompressed RGB within MXF

[Kieran O Leary]

Hi,

I see that uncompressed RGB is not supported within MXF. I know that
Resolve can create 10-bit RGB but only at HD resolution. I didn't see
anything relating to uncompressed RGB in the UL list in mxfenc.c and I
don't have an SMPTE account to get beyond the Paywall that would let
me know what RGB pixel formats are possible within MXF in a general
sense.

I'm assuming that there isn't some option that I'm missing out on
here, it just isn't supported?

$ ./ffmpeg -f lavfi -i testsrc -pix_fmt gbrp10le -c:v copy out.mxf
