#4353: DNxHD 444 from Blackmagic Resolve decodes first frame only

Summary of the bug:
On a fresh pull from git ffmpeg will only decode the first picture frame
of a DNxHD 444 mxf from Davinci Resolve and ignore the rest of the frames.
I'm simply trying to transcode DNxHD 4:4:4 to Prores Quicktime but
anything would suffice, even a sequence of jpeg files. All output types
fail the same way.
Sample file with colour bars is uploaded, filename is
ffmpeg_decodes_first_frame_only.mxf
How to reproduce:
