This fixed the problem with XAVC MXF 4096x2160. With an XAVC MXF 3840x2160 pixel size
this is not recognized and default back to 'avc1' but when using -vtag iavx this file plays
correct in all Quicktime players.

I assume it needs an extra line to detect this format in movenc.c 


Thanks for fixing this.
