Comment (by FranceBB):
By going on with the tests, I realized that this:
{{{
ffmpeg -thread_type slice -i "20210429WiganvHullFCX_C921h25m29s09.mxf"
-c:v v210 -vf "format=yuv444p,format=yuv422p" "test.avi"
}}}
Fixed the decoding problem, so not only -thread_type slice is required,
but also a conversion, despite the original file being yv16 (4:2:2 planar
8bit). If you don't put that in there, it will display green fields.
