Please check metadata with below command:
./ffmpeg -i ../fate-suite/mxf/Sony-00001.mxf -c:v copy -c:a copy out.mxf
./ffmpeg -i out.mxf
company_name : FFmpeg
product_name : OP1a Muxer
product_version : 58.65.101o
=>
company_name : SONY
product_name : eVTR
product_version : 1.00
So need to update fate-mxf fate test.

In my opinion the MXF identification set should contain data about the
application that wrote the current version of a file, not some previous file
version.
The example command shows what's change for the fate testing, if you want to
update to use your own product version, please use -metadata
product_version="xxxxx".
It looks wrong that a MXF file that is muxed by FFmpeg pretends to be
written by a SONY application. I see that with "-codec copy" you can
avoid re-encoding of the video and audio streams, and thus might want to
indicate the A/V encoder software info somewhere separate from the
container format writer software. But this patch overrides both information.

Tobias
