[FFmpeg-devel] [PATCH 3/5] avformat/mxfenc: prefer to use the existing metadata

[lance.lmwang at gmail.com]

From: Limin Wang <lance.lmwang at gmail.com>

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.
