FFmpeg does not detect Prores in Avid MXF automatically

[Steve Dierker]

Hello,
I have a file which is Apple ProRes wrapped in MXF.
If I do not specify the codec on the commandline FFmpeg is not able to encode the file, but if i specify '-c prores' it encodes the file properly.
Sample ca be found here: ​http://dl.flavoursys.com/samples/mediainfo/prores.mxf

thanks,
steved

How to reproduce:
